Big 20g ~ 402hp & 397 ft/lbs.

slowscooby · 03-20-2009, 12:15 AM

I am pretty happy with this setup. I only have a stock EBCS though, so Scott recommended me getting a MBC to even out the boost in 5th in 6th, as right now it's erratic. Tell me whatcha guys think.

Here's my mod list:

Engine:
-FP 20g Td06h 8cm
-APS 525 FMIC
-APS 65mm Intake
-Samco Inlet
-Grimmspeed coated TGV deletes
-No coolant routed through manifold
-8mm phenolic spacers
-Invidia V3 DP, no cat
-HKS Carbon Ti catback
-Forge BPV
-Perrin radiator shroud
-Walbro FP
-PE 850cc injectors
-ACT HD clutch and streetlite flywheel
-Rerouted intercooler sprayer to FMIC
-Scott Siegel tuned to 400hp with AP v2

Dyno was at S&R in Tampa, I think it's called like a "land and sea" dyno or something?

If I do anything else power-wise I would probably upgrade to Grimmspeed manifold ends and crossover pipe, uppipe and a Grimmspeed 3 port EBCS.

Nice numbers/setup. what elevation are you at?

rexworx · 03-20-2009, 02:53 AM

Wow nice power for a 20G What kind of fuel was the tuned on?

kyo126 · 03-20-2009, 05:43 AM

ur car looks amazing...i guess is insanely fast huh?

WagonGGA · 03-20-2009, 08:41 AM

Nice power and Nice looking car!!

06njsti · 03-20-2009, 08:45 AM

the 400whp 20g tune, perfect for a street car in my opinon

C J · 03-20-2009, 09:18 AM

and to think I almost didn't want to order a 20g anymore, nice numbers!

irascible · 03-20-2009, 09:33 AM

Love the numbers and the power curve, also interested in type of fuel. Very nice man.

J. Steinbeck · 03-20-2009, 09:38 AM

Oh good Lord... your car looks so good it hurts. Very tasteful looking (and tastefully modded) with power that is bound to shock the Hell out of more than a few people. I would love to own a car nearly identical to yours, with nearly identical mods, at some point.

Hopefully you won't mind if I ask a few questions...

Just out of curiosity, what did Scott tune for in terms of target boost on a setup like this?

I'm guessing that the 850s on a 2.5 with a 20G are well matched. Any idea what kind of IDCs your car is running?

Finally, what brand of FMIC are you running? (EDIT- Nevermind... I now see in your post that it is an APS.)

Sorry about the questions. I'm just playing around with ideas of what I might do to my own car down the road, or what I might do if I switch to another vehicle. It's nice to hear from people experienced with what I *think* will be a path worth following.

Congratulations on a stellar vehicle and setup.

xsblack · 03-20-2009, 10:15 AM

Graph looks good. Any idea what a stock Sti will put down on this land and sea dyno? Also how much boost you running? on pump?

Dookoo · 03-20-2009, 10:20 AM

What fuel?

Steve.804 · 03-20-2009, 10:46 AM

Wow perfect power band!! I'm sure this is an incredible street car! I'm also curious what a stock STI puts down on this dyno

02h20 · 03-20-2009, 10:48 AM

Is there any benefit in removing the coolant flow from the manifold?

Reduced intake heat.

slowscooby · 03-20-2009, 12:22 PM

I am in Orlando, FL using BP 93 octane.

Not sure what a stock STi puts down on that dyno, I will email the shop and ask.

Steinbeck - I think my target boost is right at 20 pounds. Not sure what my IDC's are, I know I have plenty of room though.

Thanks for all the compliments guys

Slimsti · 03-20-2009, 01:04 PM

Thats some sick power for not going to crazy with the turbo or boost. Nice looking aswell. Good job looks like a blast to drive.

k04sti · 03-20-2009, 01:11 PM

I believe stock STI's are around 230whp on that dyno.

Nice ride!

slowscooby · 03-20-2009, 01:45 PM

Cool, thanks for the info.

klattery · 03-20-2009, 02:06 PM

400 whp on 93 octane for a 20G seems pretty high, even for a higher reading dyno. Also, you're still running 65mm intake, and not maxing out the MAF.
I don't really care absolute numbers, but I think a lot of folks will be unhappy if they expect 400whp from a 20G on pump gas (even 93).

Most important thing is it's a nice powerband and nice looking car.

godforbid67 · 03-20-2009, 03:14 PM

nice nice, car looks sick man. that seems like a lot of power for only 20 pounds on a 20g. you sure stock stis only put down 230 not 250-260?? must be a fun daily driver though.

checque · 03-20-2009, 03:26 PM

Super high reading dyno. My 20G with cams and headwork makes that kind of power at 25psi on 110.

My DW850s are at 88% on a built 2.5 with 264 cams and lots of porting. It's amazing how some people can run 850s with a GT35R . . .

slowscooby · 03-20-2009, 03:41 PM

I emailed the shop a bit ago and asked what a stock STi puts down.

It may not "actually" be 400hp, but it feels damn good

If they are running 850s with a gt35r then they are not using that turbo to its full capabilities at all.
