Finally got off my ass and went to a Street Meet. :yes:

R33 GTST, stock clutch, turbo and suspension, standard bolt on mods, 197kw @ 0.85 Bar

Front 235/45/17 Dunlop FM901s Rear 255/40/17 Potenza GIII @ 35psi, lowered to 33psi at the end

First couple of runs @ 0.7Bar

Run 1 - me:

60' 2.433

ET 14.971 @ 96.37 MPH

Run 2 - my bro

60' 2.733

ET 15.278 @ 97.22 MPH

Was misifiring (needs retune) so boost wound down to 0.65 bar

Run 3 - vijay

60' 2.221

ET 14.892 @ 95.55 MPH

Run 4 - my bro (vs GTShortie)

60' 2.343

ET 14.730 @ 91.19 MPH

Run 5 - vijay (vs GTShortie)

60' 2.107

ET 14.516 @ 95.78 MPH

- It was the first time ever at a drag, let alone competing- never seen the staging process or the 'christmas tree' until we were racing. Our first races we both staged 2nd and wasn't ready for the start. By the end of the night I was staging early and waiting to drop the hammer

- I can't do burnouts. Last one of the nite I tried to step onto the brakes but I think I did it too much

- Shifted too early, around 6500rpm

- Dropping stock clutch does NOTHING for launches. Tried it the 2nd time and tramped badly.

- Retune next month, so I can run on high boost

But it was the best rush! :) Definitely be back there soon...

Anyone got any advice from the results??

1. At a street meet it doesn't matter if you launch immediately after the light turns green or wait a few seconds then go, your ET will be the same (reaction time doesn't matter), so stage up, compose yourself, then go when you're ready.

2. Don't worry too much about the burnout unless you're using soft semislicks.

3. Try lowering your tyre pressure even more, with 255/40/17 i'd be trying to get more sidewall flex by going as low as 20psi, but its a matter of trial and error.

4. What mods exactly do you have? I would have expected 95-97mph from a car making under 150rwkw.

What rpm are you launching at? With 255 rubber on the rear (drop it to about 20-25psi) you would be dropping the revs from around 4000-4500rpm i'd think? If you can nail a 2.0sec 60ft time you will drop close to a second instantly.

Rev it out more before changing, up around 6800-7000rpm somewhere. You may even be able to hold 3rd gear across the line and should be doing up around 100-102mph.

Hi, i've got virtually a stock car running a 3inch exhuast, stock clutch stock boost etc etc, my first time at the drags got me from a 14.6 down to a 14.1 at 97mph.

1st run = 14.53 at 96.4mph

2nd run = 14.32 at 97.15mph

3rd run = 14.11 at 97.7mph

4th run = 14.23 at97.5mph

5th and last was 14.64 at 96.4mph ( stock clutch gave up the ghost and slipped from the get go).

It was a great night and i will be going again now that i've got a new clutch and boost controoler. Can't wait to see what it will run now. PM me when you go and if i can i'll meet you there! Lots of sau ppl go.

      It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.

      By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.

      There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again?
