This dyno run was in my 1999 impreza 2.5 RS with an 07 STi Limited swap. The transmission is the stock RS 4.11 5 speed, and the motor is running stock ecu, air filter, exhaust w/ cats, etc. No power mods at all.

Here it is...

almost forgot... Thank you East Coast Swappers!!!

wow.
lucky you

dyno pack?

ECS rocks, no doubt about it.

XX_Chris... I have a feeling you will be seeing me and my car sometime soon, just need a downpipe for my 3 inch exhaust to be complete...

dyno pack?

Dynojet... I don't know if they're the same. ICS performance in Stamford, CT

270whp! damn that dyno reads pretty high.

Who wrecked an 07 Limited already? Poor fool.

270whp! damn that dyno reads pretty high.

275whp on a bone stock baseline! Just a tad high :lol:

I was thinking the same thing!

Who wrecked an 07 Limited already? Poor fool.

There were "older" (04-05) STi's with Turboback exhausts and such there that day, they were putting out 250-255 which is right where I would expect it to be. I know the 07's are putting down more power than ever, and maybe my lower gear ratio 5 speed had something to do with it... or I dunno. Maybe I got lucky with this motor. Thanks for looking though!

270whp! damn that dyno reads pretty high.

Cough... 275 (jk)

Nice numbers! I bet that GC flies!!!!! :devil:

Gears have nothing to do with HP ratings if the software is set up correctly.

Interesting... I did specify as the car was going onto the rollers, that it had the stock RS transmission, and I do remember specifically saying 4.11. Regardless, if you are a non-believer, stop by sometime and I'll take you for a drive... = )

I would assume less drive train loss through the 99 2.5RS tranny and drive train. Smaller axles, smaller brakes, different diffs., ect. That is probably why you are seeing more power than a normal STi would on that dyno. Congrats on an awesome swap.

275whp on a bone stock baseline! Just a tad high :lol:

:lol: gives me a whole different perspective on the gains of al's tunes.

That's crazy! I went there too at around 1pm. I put down 285whp on a Cobb OTS St. 2, Cobb SRI, Cusco DP, Buddy Club CBE, Fujitsubo Super EX mani, and a Hyper Force system. Just out of curiosity, is your car a 2Dr?

edit: This is an 05 STi

yeah, 2 door... I don't think I saw you there, I left around noonish...

Just curious how easy it is to smog a car after a swap? Or do you not have smog laws in them there parts.

I live 5 mins from ICS, their dyno is a bit high

I picked the car up from East Coast Swappers, and passed emissions on my way home that same day. So I'd say, it's pretty easy!!! and yes, we have smog laws in CT.

That's awesome!

XX_Chris... I have a feeling you will be seeing me and my car sometime soon, just need a downpipe for my 3 inch exhaust to be complete...

Sounds good.. But I will warn you, we are doing our own baseline when you get here.. :D

We should have the guys from ECS down when you tune.. good guys, great work, tuned a lot of their setups... Paul is awesome and probably the only guy on the planet I would let do a swap on a GC if I ever get one.

Either way, nice setup, sleeper, and I love sleepers.

270whp! damn that dyno reads pretty high.

My 07 STI reads 242 AWHP, so it dosent read high, it must be the factory transmission not robbing the horsepower.

So what if the dyno reads a little high- that car friggin rocks!

Nice job and you might want to start looking around for a spare tranny. With that much power yours might not last very long. Mine lasted 2 years with significantly less power and fairly constant abuse. :)

Sounds good.. But I will warn you, we are doing our own baseline when you get here.. :D


You should do the baseline with the car exactly how it's setup now, for comparo. It would be interesting...Then install the DP and tune.

nice car man, sucks ass though you bought an 07 Engine with that time bomb of an engine. Good luck, get that bitch tuned Asap

Kick ass car man. I love it. I would leave it alone. But WTF is up with that ICS dyno reading a stock STI drivetrain at 270whp?

Its Barry Bonds' car

Thanks for all the kind words guys, and sarcastic jokes too... = ) I'm sure the dyno might read a little higher than some others. I know that I was paying attention to the 11 cars that went on the rollers before mine, and the numbers were not sounding high at all. They seemed to be right on with what I and others expected. Anyway, as soon as I get a downpipe and some cash, I'll be making another visit to a tuning shop, and then posting up the results.

I think exercising a little skepticism here is a good thing. I remember hearing about how a temperature reading could be thrown off and corrections can become ridiculous on a dyno. Or how the corrections in general can be played with. We're just going with what's more likely. If XX's dyno corroborates, then it may get a little interesting.

J

so does this have the stock 2nd and third members?

Tranny and diffs etc etc?

I hope I read something wrong.

If not good luck.

love the swaped gc--i will be starting mine very soon.

dave

sick car. i wish my GC had that kind of power

so does this have the stock 2nd and third members?

Tranny and diffs etc etc?

Not sure what you mean by members, if you mean crossmembers, yes. The transmission is the original 5 speed, and it's crossmember, and the rear diff and it's crossmember are all stock too. You didn't mis-read. Thanks for the good luck, but even better, I have common sense, and I don't plan on abusing the car by going to the drag strip, etc.

Glad you guys like it, GC STi FTW!!!

I think your numbers sound just right given your significantly lighter drivetrain/powertrain.

Enjoy it, i heard mine fire up the other day... :devil:

nice car man, sucks ass though you bought an 07 Engine with that time bomb of an engine. Good luck, get that bitch tuned Asap
Please elaborate. Or maybe you meant a time bomb of an OEM ecu map.

How many cars have you tuned again? Remove your mouth from the haterade bottle...

way nice man! congrats!

THis guy has no idea what he is talking about. THe 07 is a strong engine. Its the idiots that Dont understand the ECU.

Clark

represent sleepers....that must be stupid fast! have you upgraded the braking system yet? suspension? she'll need it BT

Good numbers, actuallly very good numbers. Grats.

Lighter/smaller wheels, tires, brakes, axles, etc. cause less loss to the tires. A stock 07 would undoubtedly read lower on this dyno regardless of how this dyno compares to other dynos.

Nice car!

nice car and big props to ECS they built 2 of my swapped cars and are building me a drag race gf wagon ECS FTW:D :banana:

javier

Thank you all for the compliments. I agree with you innovate tuning, I think the completely different drivetrain attached to the motor, that's lighter, and geared lower is obviously not going to yield the same #'s. I'm glad I was able to get one of the first dyno sheets up here of an 07 swapped GC. As soon as I go Stage 2, you'll be hearing from me again = )

Javier... I think I saw your car there on monday. Did you have those huge chrome rims on your wagon? You're getting a built motor and such from what I heard... Congrats, I'd be very excited.

Not that it makes a huge difference, but viewing the plot with no CF or smoothing bumps the peak numbers up a bit.

Either way, the difference between that power in a GD and the same power in a GM chassis is huge. I'm looking to get mine on a dyno soon.

take it to the track.. trap speed is a better measurement of how much power its putting down.

Clark I wrote in an earlier post that my first 07 STI made 248 WHP. There is nothing wrong with my dyno. This car does not have the 07 trans or differential. It could very much have less drivetrain loss than all STI's. Someone should do some research on the RS drivetrain rather than look to blame the dyno. :)

There's a lot of margin for error in that as I went from 112 to 115 with nothing but practice.

Better start saving for a tranny...or dont got WOT in 3rd....you will break it quick :)

4.11 final drive contributes a lot to this number.

Who wrecked an 07 Limited already? Poor fool.

not sure what you're bragging about here?

a high reading dyno? yippee!

He is like 500 lbs lighter. LOL. He's gonna trap around 105-107.

Gotta love the haters . . Congrats on a nice set-up and a quick car!!

Who did your swap?

East Coast Swappers, as stated in the second post...

Thanks Aladdin, and Gabe, I'll let you know once I decide to take a pass at the drag strip. I haven't had the balls to beat on my stock tranny like that yet.
Nick

bump

don't kill me, i'm just excited about my own RSTi...it's a 2000 GM (i think? it's a coupe; i believe GC is sedan) with 05 sti motor

i won't drag the car at the strip since i plan on using the RS 5spd for as long as i can...

i will try my best to put my RSTi on Harman's dynojet here in socal; stock Evo 9's put 250-270whp on that dynojet so it'll be a good reference point.

the GM already weighs 450lbs lighter than an Evo/STi...if due to less/lighter drivetrain components the motor puts down more power...that is double win. can't imagine what my RSTi can do to a stock Evo/STi in a straight line (wish i still have my evo 9 for a quick comparo :D)

cheers.

Clean looking engine bay. Is yours having any of the hesitation problems other 07 STIs are having (sorry, it may have been asked already...just to lazy to read through all the posts)

Erick - Yes, my car shows the same symptoms as the other 07 sti's. I'm still driving the car completely stock, and boost it up regularly. It's amazing how fast the car is, and how well it runs considering how horrible they are tuned from the factory. I am anxiously awaiting the day I throw on my turboback and go get it professionally tuned.
Nick

Congrats, go stage 2 with it and get a protune..... My RSTi put down 325awhp with a 05 STi motor, stock tranny/diffs/etc., intake, cobb ap, and invidia tbe!! These RS's are super fast with the 4.11 final drive!! Anybody who doubts it, line up with one!:D These cars(near stock) will rape cars with thousands of $$$ into them. First thru third gear will wrinkle your clothes!!:lol: They're definately not the best on the interstate though.

holy dog **** 325whp...what was the torque?

i don't know man, my 3rd and 4th pulls pretty damn hard...and i'm still stock.

my Evo IX with bolt-on's and tune was trapping 112mph and the RSTi's 4th gear doesn't feel THAT much slower in comparison...but again my butt dyno ain't the most accurate thing either.

500lbs deduction in weight goes a long way IMO, even though as speed increases it doesn't play as much a factor - remember that the 2.5RS has a better coefficient of drag too (most likely due to less frontal area)

EVo/STi Cd is around .35 IIRC, GC8 is around .32. over 100mph Cd plays a big role, along with gearing.

the 2.5rs coincidentally has the exact same gearing as my Evo IX...every gear tops out at the same speed @ 7000rpm :D

How much does your car weigh with a stock swap? I was always curious how much weight a swap would add to a RS

i was told by Garage Tuning that the STi block will add 50-100lbs to the car...but the figure is closer to 50 lbs

2.5rs weighs 2825lbs or something, impreza L is in the 27xx...so around 2900lbs would be my guess for a 2.5rs + STi motor ONLY. it's still a good 450 lbs off of the STi (3350 lbs)

with a 6spd in the 2.5rs expect another 100lbs...so you're looking at a 3000lbs car.

nice car, looks clean

What octane are you running? I have not seen one post about that. Maybe he was running a 97 mix or some ish :)

How does the car trap?

wow..

I haven't weighed it, but I am going to soon. I drive past a truck stop regularly.

I've ran nothing other than 93 on the street or dyno. Once I could only get 92, and it ran ok.

I have honestly been too busy to enjoy the car, so I can't answer that yet. In 5 weeks I will be graduating college, and then it's playtime...

Thanks for the comments!

This is the SLOWEST '99 GC, '07Imprezza WRX STI Limited swapped car I have ever been in.

What did you guys do with the air pump, I mean how did you delete it?

Wow.... nice setup indeed!!!!

I would love to do an STi swap in an RS... such cool cars... Imma keep an eye out for your whip!

car looks good. We should try and get a meet together, never knew there were so many of us around hear.

Holy Shizzle pops! Clean and wow what power! That thing must rip!

Nice numbers dyno reads pretty high though.

What did you guys do with the air pump, I mean how did you delete it?

+1 howd you delete that pump?

My car wants what your car got. Lucky lucky car.

Anyone want to guess how long 2nd gear will last?

you take off the pump, plumbing, and plastic air chamber. then you put a block off plate on the drivers side head to replace where the air pump plumbing used to attach, pretty straightforward.
you need to keep the valve on the car and plugged in though specifically on the 07 otherwise your atmospheric pressure sensor wont work properly.

Gears have nothing to do with HP ratings if the software is set up correctly.

Drivetrain loss is less with a 5 speed than a 6 spd.

My car wants what your car got. Lucky lucky car.

Anyone want to guess how long 2nd gear will last?

mine was 5000 miles. stock '05 STi motor.

granny shifted no matter the circumstances, no launches, always lifted to shift, let the synchro's catch the gear etc....too much powa (torque) is too much powa, or the previous guy beat the hell outta the tranny...

Garage Tuning took apart the tranny, the 2nd gear plate looked almost circular :D teeth were all over the case...rest of the gears looked brand new though haha

I've done around 10k miles so far, beating the snot out of the tranny with no problems so far = )

hilarious TK!

Fo Sho!

I have about 2,000 post-swap miles on my RS trans with a few drag race nights. 2nd gear's fine, but 1st gear and the center diff are really noisy.

275whp on a bone stock baseline! Just a tad high :lol:

That was my basline running a Stage 2 with the COBB OTS map on 93 oct :lol:

Protune got me 304WHP/335WTQ on Stage 2 ( :rolleyes: soo long ago)

Well, the Dynojet/no CF/no smoothing boosts the numbers a little.

I've done around 10k miles so far, beating the snot out of the tranny with no problems so far = )

yea i'm pretty sure mine was just due to former owner abuse...

now i have the 6spd mated to a '95 open diff. r160 and axles..let's see how long these toothpicks hold up...any guesses?
