I just picked up an Evo a few weeks back. The car has an AMS GT30 turbo kit on it( says .60 trim on front, cant see the back side), with turbo back borla exhaust and GSC stage 1 cams, removed MAF intake and made custom 4" intake right to turbo, tune by me on the Fcon to about 342 Dyno Dynamics WHP at 25 psi(translates to about 380 on a Dyno Jet), stock motor, Exedy Twin disc...

My question is, with a full weight evo and my fat but driving, Im 290lbs, on that current pump gas tune what kind of 1/4 mile times could I expect? Im not familiar with launching the Evo yet and dont know what I should set the 2 step for either, but the Fcon has a really good 2 step.. I would leave at 10 psi in my Nissan 350Z off the 2 step

So...Being i am a fairly good MT driver and have hundreds of 1/4 mile passes under my belt in my Nissa.

What should I launch at?
What could I expect 1/4 mile time wise?
Do I want to powershift or would a WOT BOX shift be better?

Thanks for the advise,

Evo Newbie..

first off welcome to the community! sounds like your coming from a nicely boosted 350 which is a fun car, but you will def love the evo. cant really help you guess on what your times will b bc im not too familiar with that turbo set up, but coming from my personal set up my 2 step is at about 5900 rpms and works well. your clutch should be able to handle the power but just make sure you slip it otherwise you will be in the market for another t-case soon. again congrats on the switch and enjoy!

Julian

Yeah, the T-Case is already whining like crazy...Sending the tranny and Tcase to Shep soon for the rebuild..

Launch somewhere between 5800-6300rpms. It's going to be up to you to find the sweet spot between launch rpm, tire pressure, and the track prep on that particular day. Keep the clutch just barely out of engagement and as soon as you feel the clutch engage quick slip it as fast as you can, don't dump it.

As for shifting it's up to you but you will get the best results with power shifting the whole way down the track at wot. As for shift points, look at your dynograph if you have it and estimate what rpm you should shift to fall back into a good point of your powerband without running it out of your powerband up to.

Hello Julian, glad to see you on the EVO side!

If you made 340-350 correction less on the DD you should see around 117-119mph
If that was on a 1.1 I would guess around 116mph, 1.2 and you will be seeing 112-114mph.

I have to 2 guys on here with AMS/BR 30r kits. The one made 430whp on the turbotrix Dyno jet and trapped 123-124mph on straigh 93, the other made 500 on the DynoDynamic @ the shop with a 1.2 correction and trapped 129 on racegas.

My guess with some driving you will see some 11.6-11.8 passes.

You guys are very close to my house... I will have to check the shop out.

Julian

So the car should go mid 11's with a decent driver then? Now Im adding a meth kit this week..

Few more questions,
what would be the Evo Stock motor limit safely tuned on meth and pump??

What WHP do I need to go 10's at full weight?

Thanks in advance...

Evo Newbie..350Z pro..

Julian

Hi there Junior...Glad to see you still love me
The DD you guys have at the shop is an older version with a 20% correction applied then is what your saying?? So that 500whp car is a 400whp on a true Dyno Dynamics?? Not to bad, Stock motor??

We use a 13% or 1.13 on our Dyno and find it to be dead nuts with any Dyno Jet. The newer DD's will not allow a correction at all that the 342 we got compared to the previous tune.


Cant wait to work out my T-case issues and hit the track next year.

Hey Julian how goes the Fcon over your old tune hehe Im hopefully finally finishing up my problems with the Air Fuel bouncing all over the place.

Adam

Julian

Yeah, that was the same issue i was having.The reflash seemed as if it was a 10 minute cookie cutter flash, loaded in and several WOT pulls on the dyno and sent on their way. I was ready to get rid of the car after 3 days of driving it to and from work.The A/F was all over the place, the car would dump to the 9's if you gave it throttle while cruising, I was getting 12mpg with the old tune, and couldnt even drink a cup of Coffee while driving since the car bucked so badly. There was many drivability issues, misfire codes, O2 codes due to them not being able to compensate well enough for the fuel trims..
IMHO if your putting big injectors and a big turbo, you have gone pretty extensive to that point, why not just go the extra distance and put in a real ECU like the Fcon..But thats just my personal opinion...

I might try to get to the track tonight weather permitting, just to see what it traps. No hard launches as I hurt my T-Case.
