My 2 mods lost to friend's GS-R

[jake98gst]

Man I can't wait until my car doesn't suck anymore...

I raced my buddy's 96 Integra GS-R moderately modded...same 'ol honda mods, but quite a few of them. Well anyway, I lost...from the start. But my only mods are intake and mbc (spools to 15 then falls to 12-13 from 3.5k on up). I thought I would at least take him off the start as his car isn't shit until vtec but I have zero top end right now. But I guess once I get my full 3" exhaust I'll waste him... I hope. I'll keep faith in my dsm and just wait for speed to come.

Don't feel bad man... the exact same shit happened to me... This GS-R's are quick, but once you get your exhaust you will have no problems

i dont get it i beat a GSR with I/H/E and all i had was intake, BOV, and catback. Does a catback make that much of a difference

FYI the next mod you should get is a 1G BOV then you can hold 15psi with no problem.

That's what I am saying... back when I only had exhaust I destroyed my boys GSR by like 2-3 cars from a 40mph roll to 90mph. On the highway I walked him even harder.


If he has I/E/H GSR integra's with a good driver can touch 14.9

 

[talonawd94tsi]

u need a bov for your next mod,

then you will see 15psi all the way to 6k or a little more

 

[jake98gst]

BOV's on the way...

BTW, it's not like he just had i/h/e...he has been dumping shit into that car for 2 years. Not sure on what. I know he's done some ignition stuff, other than that I dont know.

BTW, it's not like I got destroyed. I was at his quarter panel that whole time, he was just pulling on me slightly. When he shifted, I caught up...(A/T) but he pulled slowly again.

Thanks for all your comments...

You need a MBC and a Boost Gauge w/ a BOV that holds more than the 2g BOV.

Turn it to 19psi and then you win.

Are you kidding? A T25 at 19 psi!?!?

Your GST is automatic ?

that explains it why he was so close.

Turn up the boost and walk him next time.

Yeah turn it to 19 psi so you can hit fuel cut and have your timing pulled good idea. But once you get your bov you should hold 15 psi's then race him again and see what happens

So you have done this before

As per the secound rule in 'When replying to a discussion' I have done this. Matter of fact I ran it like that for about 4 months. Not once did I hit fuel cut. When I put the 20G in I checked for play in the T25 and found what would be expected from a 35,000 mile turbo. Very small at best.

I am not saying for everyone to run it like this all the time. But if you turn it up for a night and find your limit for your 'fuel cut' then do it every once in awhile. I ran it like that EVERYDAY in EVERYDAY driving. This is my daily beater and I don't plan on making it a JEWEL that is not to be pushed to the edge.

Here, this is what is on the board. He is not the only one to do this, just the only one to post an actual dyno. 210 whp will get you past that GS-R!

I ran mine at 19 for a year and a half. Never hit fuel cut once.

This is a great idea. If 13psi at the drop off didn't win, a simple holding of 15 is not going to get him anywere. It falls a 3.5 rpms and at about 5k in the rpm range it (THE T25) falls on its face.

He will still lose without any more mods. He lost from the start, it wasn't like he had him and then just lost.

 

[jake98gst]

Those who run 19 psi on a t25...What did your logs look like? How were your O2s?

Jake

 

[nine5raptor]

02's (which are worthless) stayed over .94

Timing increased steadily to 15 at the top of each gear (of course by then boost was about 11 or so). I ran a 14.6 at 91 in 100+ weather with track temps over 130 full weight like that.

With that being said, throw the T-2small in the trash and get something bigger.

 

[PieTSI]

19psi is way past the t-25's efficiency range. Why risk hurting the turbo or your motor, when at 16psi you get more power? And you say you ran a 14.6 with a t-25 at 19psi. Well I ran a 13.7@100mph at 16psi full weight also.

^^^^Exactly what I thought, until I saw you were AT. You can still take him I think with a little more boost

risk? what risk? I was logging it and everything was fine

when at 16psi you get more power?

I wasn't knocking and was flowing more air. You are making wrong assumptions

And you say you ran a 14.6 with a t-25 at 19psi. Well I ran a 13.7@100mph at 16psi full weight also.

Whoop-di-freakin-do. Good for you.

If you are hitting fuel cut on a T25 for any reason, you have some problem elsewhere on your car. The T25 flows 250cfm's at 15psi, so anything after that and its downhill from there. Run 15psi. If you had a huge front-mount, then 19psi would be fine, but a small 16G is going to outflow a T25 at any boost. Small 16G is going to put out 505cfm's at 15psi. With that you could easily walk him, and they only run 500$.

 

[nine5raptor]

Remember flow is based on pressure and density. You can throw a T-101 on there and it won't outflow the T-25 if your valves/tb/intake mani won't allow it.

True. Most DSM turbos on todays market are not hindered in that way though. You would need a turbo that large to start realizing restrictions elsewhere on the car.

GS-R puts out around 147 whp
GS-T puts down around 165whp.

However, put an intake and 3' cat back and you should be up around 180whp. Cat back can make up to 20whp in some cases especially if the cat is removed. Downpipes also can make a lot of whp. So yes it can!!

Quoted flow rates don't really mean anything. It is like buying a car. You buy hp, but drive torque.


Looking at compressor maps for the s16g and the 14b, at 14.7 psi and 17.2 lb/min, the 14b has a higher efficiency rating (78% vs 71%) thereby heating the air less and maintaining a higher density while still pushing against the valves the same (14.7psi). This means the 14b will flow more and make more power than the s16g at that boost/flowrate.

Look at the weight difference though. DSM's are porkers.
