Im planing on playing around with the 2step, Im going to start at 10psi then add on from there. And still in the air where im setting the rpm's at im thinking around 6600rpm.

It all comes down to playing around with the settings once you car is tuned for everything else. Everything else is getting out the hole and getting the right suspension setting your gold.

Its when you setup to 45R is where you should start to worry about spraying off the line. I talk to david about this about a year ago. He made me change my mind from 45R to 42R.
I'mat 7950 with my 2step right now to get a good launch

Just remember how loosely the term "2 step" can be used. There is a difference between using a 2 step cut vs using the same with antilag.

hmmmm thats funny the same turbo as whats Norris design is using! lol

its the 42RS (or the 4202), the big bad one that the tuners are running.

Norris has proven, and im sure they like of AMS and Buschur are getting the same, that you will be seeing full spool by about 5K! thats not that bad form the graphs i have seen on here for 2.0s running 35rs!!

stop being a p*ssy and go for it!

Chris.

You're using a car for a comparison that runs straight meth and a dogbox. A 4202 off the bottle isn't going to hit full boost until 7200-7500rpm.

sorry mate but your wrong. norris, and im sure AMS and buschur, run race fuel not meth.

see this spec sheet for Norris's car. he is running VP import race fuel. gd know what this thing would be like on meth! lol

http://www.norrisdesigns.com/demo9.asp

if you are planning on running a GT42 you getting VERY serious! you are going to have to make compromises. if you want that much power and keep it as a daily drive, i think you have picked the worng car! try a viper.

can i ask where you got the 7200-7500rpm spool times from? it just i have seen an engine dybno vid that show Norris's Evo getting peak torque (normally when full bost hits) by 5000rpm! oh and thier motor is making 700+lbsft at that point!

see the 4th vid down to see norris's engine on the dyno to prove this. also there is a load of other vids that show you just how driveable his car (im sure Buschur's and AMS's Evos are the same) around a track.

http://www.norrisdesigns.com/videos-evo9.asp

AMS say very similar things. full spool on a 2.3 by 5000 to 5200rpm see here: http://www.amsperformance.com/store/...roducts_id=515

just shows you how good these cars really are!

thanks Chris.

7,950. You must not be using anti-lag. With my little 35R 5,500 two-step with anti-lag I" leaving at 1.3 bar. You don't need "juice" to spool the turbo it's not that big, good luck.

I'm talking about 2.0l applications. My numbers come from the experiences I have had personally watching a few 42r cars on the dyno and seeing the sheets. Seeing as how the thread starter has previously put up his dyno graph of his T67/Ptrim and peak torque happens around 6k or so, I think that he realizes his power band is going to continue to shift to the right with an even larger setup.

Again, it isn't worth arguing. I am a realist and only trying to help him out. It seems like he felt some grief in his other thread about expenses concerning his Tilton clutch. Things like 10krpm and antilagging are only going to make things worse financially. That was my only point.

O i know i can use anti-lag but ive got this crazy mechanic that wants me to learn how to drive by modulating the clutchHes afraid of carnage if i use the anti-lag and 20-30psi of boost off the line. I'm running full slicks and cutting 1.52 60ft times. With the ant-lag i could cut 1.4 60ft but i could see myself shocking the drivetrain

hey mike 99gsx, sorry didn't meen any offence. i must have read something wrong sorry mate, thought he was talking about strokers. your right thought, the 2.0ltrs do seem to have to spinn the nuts off to get these things spooled! and your very right about the money thing! people seem to forget about all the cost that come with power. there is no cheap way in the end i guess.


ifarted2, go for the anti-lag! lol. sorry i got it worng (agian! lol) about AMS. dam it! lol

are you looking to go stroker or keep it 2.0/2.1???

Chris.

The turbo you are getting will work fine. And a 2 step will be fine for getting the car moving.

That turbo is not a regular GT4202R (74mm wheel) ! This turbo uses 76mm wheel compressor with GT42R turbine.

You will NOT see full spool by 5k. Lets not be rediculous again on this forum.
With that said it will be very laggy for the street, but I DON'T see you needing a shot of nitrous to spool the turbo up. It will do just fine once you get it going thru the AEM 2 step.
