Default TWE tuned.. 14.3 unconfirmed tho..

Granted, there's no timeslip, and it IS on their website and stuff, but if its true, pretty impressive.

not really impressive, more expected. If you got equal length headers, exhaust, cams, and porting, I hope you're pulling a low 14 sec 400m.

I believe those numbers. I talk with Keith quite a bit and totally believe that their handwork could build a car pulling those #'s. I will be truly impressed if the guy pulls 13's, but as mentioned 14.3 isn't super fast for an NA build...

Yeah, i guess so . I am goign to maintain the fact that the intake manifold is a huge power restriction, I was able to pull a 14.10@95.5 as my best so far, with 17" speedlines. The welding of the manifold is probably going to start next weekend, but everythig is in that we need, except the velocity stacks. Then we will see if my bottom end work will show through.

Seems, like the manifold will keep us out of the 13's no matter what we have (except nitrous).

It's still not considered impressive even though it's an N/A AWD car pulling these numbers?

I know there are probably boat loads of them but can someone post other car makes that run 14 seconds or less in the 1/4 mile with AWD? I'm curious!

Oh yeah and wistful, that Techworks time is impressive.

If you got equal length headers and exhaust you can break into the 14s(according to brullen at least). With cams and the basic bolt ons you should be running mid to low 14s. So these reults are pretty typical in my book, cool but nothing unexpected.

Dan, those 17" Speedlines are slowing you down, bro. What do they weigh, 17-20lbs each? Try some Kosei K-1 wheels, the 15x7.5 et45 weigh 12-13lbs each, move a lot of rotational mass towards the center, and should allow more sidewall flex for your drag start. If you want a ton of cornering grip, that's what max performance tires are for.

To those who say they won't fit, my car had 17x7.5 et40 wheels when I bought it (used), they fit with 215/40R17 tires with no rubbing. I switched to stock 16" wheels, the gain in acceleration was very noticeable.

Yeah, i know, i just didnt have time to swap rims before I went to the track. Earlier in my build, i went with my 17s on and then with my 16s on with winter tires. My times were more than .1 seconds faster, so i was not happy with myself, i just didnt plan the day out, i decided to go at the last minute.

Dan

Thanks for the rim reccomendations though, i am looking into rims for tracking my car and the 1/4 track. Ill look into them!

I believe Gary Sheehan uses Rota Subzeros on his race car.

They weigh in at like 14 lbs a shot for 15's and only cost $550 or something for the pair.

Not exactly volks, but talk about cheap!

Id need 16" for my brakes, are they much more expensive? my speedlines weighed 21lbs I think without tires.

My comments were taken out of context. Someone had expressed skepticism that that car was even capable of putting down the numbers it did. I was giving props to TWE and whoever owns the car and said I fully considered them legitimate. I went on to say that 13's would be TRULY impressive and never meant to imply that 14.3 wasn't impressive.

Sorry Matt! I honestly didn't know if it's impressive or not anymore. I get all giddy when I see any non-WRX subaru hitting the 13-14 second range, be it turbo'd or not. I'm still leaving in the past when the 14 second range was the, 'oh-sh**, that subaru is blazingly fast' range.

I'm just trying to play catch up since more and more N/A scoobies are in the 14's and touching on the 13's. Don't mind me!

Kevin,
No worries. I just wanted to make sure I was understood. I wasn't completely clear that while I don't consider low 14's that fast, they are still impressive for an AWD NA vehicle. But when Dan gets his clutch replaced and runs on 16's and breaks 13, like I know he will...that will be TRULY impressive.

And of course when his manifold project is done, I'll be knocking on his door to make me one so I can have a "13 second RS" too,when I am done with my build. Dan already sent me an e-mail telling me I better not beat his time with my build. I told him he had nothing to worry about because even though I am building a 13 second capable RS, I am not a 1/4 miledriver and highly doubt I could get it to run 13's. Maybe I just need to find a ringer to drive it for me so I can truly, with a time slip claim that I own an NA 13 second car.

Low 14ís on the stock intake manifold is impressive no matter what. That said 14.3 @ 93 was done about 2-2.5 years ago. I am not trying to detract from the new guys in any way, but it is not a milestone that is new and is what should be expected with head and cam work. However, knocking a couple of tenths off and hitting 14.10 @ 95 is impressive, especially since there is likely the least more in the car as it sits now judging by the MPH.

Hey Josh,
You wanna pilot my car to try and get some 1/4 mi. numbers once it is done? Afterall you guys are building the thing...

1st step would be to drive it down to sea level Matt you ain't hittin 13's up here... with an N/A subie anyhow.

I am VERY curious as to what your P&P/cammed/bolt-on RS will do at Bandi though.... I predict 15.5 with a good driver, maybe lower (for the rest of the viewers - we live at 5500+ft above sea level)

I'm shootin for a 16.2 this spring with a new clutch and a Cobb MAF intake (soon to be released - for real this time ) I'd be happy with that.

Chad,
Don't forget this engine will also have 12:1 CR on a closed deck EJ257 block and *crossing fingers* engine management by Cobb/AccessECU reflash. I am still looking at several options to deal with the choked intake manifold. That is really the only piece of the power equation not figured out yet. But I haev talked to a number of people/tuners that one of them has to come up with a workable option.
And yes, the altitude does get in the way of fast times...But I am not building it as a strip car anyways. This is a rally/track build. But I will come out to Bandi just to see what a duffer like me can do, this summer once it is assembled...

I was told not to go with 12:1, otherwise I would have...did they tell you any downsides to doing that? Im curious to hear other opinions please. Thanks matt! And if the manifold does work, Ill send you my dyno sheets and you can see if you would like one. Its no problem making a few extras, although I bet yours will be prettier than mine for sure! Second time around is always better.

If they are sure it is safe then i wish i could sell my pistons, but I cant unless someone has the same block as I do, or bores it out the same specs. Oh well

On more than one occasion Josh has told me that they can do 12:1 CR pistons for me and it will run on pump gas for daily use. I would likely run higher octane when racing, which will be the primary use of this car anyways now that I have the Turbo Legacy project in the garage as well. He said for pump gas you would likely want to pull timing and lose a little power, but would be able to fully reap the benefit of the pistons with race gas. With your engine management you should be able to tune that bad boy. It will just require a daily map and a race map.

When I was talking about my build with Keith at TWE their new high CR pistons were just coming out. They now list their HO pistons as 12:1 in the products section, even though the press release from September talks about 11.2:1 pistons...

Also, what is your over bore? TWE's are available in stock and 100mm. And I wouldn't be surprised if either company could do them to spec for you if your is different...

Running 12:1 on pump gas is possible im sure, however, it couldnt hurt to put a little octane booster or race gas in your tank at the track.

As for the Rota Subzeros, 17 x 7.5 will run $550 for a set and they weight 17.5 pounds each. Thats three pounds more than the equivalent Volk-TE17 but also $1400 cheaper. See site below:

http://www.oakos.com/Merchant2/merch...gory_Code=1000

The 16 x 7's cost $488 for a set. These weigh 14.5 pounds apiece which is again 3 pounds more than the TE-37's. See site below:

http://www.prolightstar.com/wheels/rota_subzero16.html


Note: Im just infactuated with TE-37's Plus I see them as a good comparison for ultimate light weight wheels.


EDIT: Stock wheel weight is 16.5 pounds for 2000-2001 RS.

Matt Monson - it's quite unlikely to run 12:1 C/R on 91 octane pump w/o proper headwork (ie: redesigning the combustion chamber). Not to mention, that intake manifold becomes extremely restrictive quite early.

Don't hold your breath for the Cobb intake. He kept on telling my friend last year that it was going to be released on a certain date, then he pushed it back 2 weeks. Did that maybe 2 to 3 times and my friend said screw it, it's not worth waiting for. This actually was exactically one year ago. I don't believe anything Cobb says.
