Hi guys hope every 1 is getting ready for the weekend I have a quick question, How many of u r boosting more than 1.2 and how many of u r sure that the block will handle?

I have it all... L19, ARP, race gasket, pistons, rods, ported and polished heads and intake, and so on....

 

people are boosting well beyond that. a couple people are boosting 23psi that are on this forum right now. bigBriguy & mraturbo to name a few

 

Thanx my man I hope i get thier feed back on that mybe we can share setups and then get to have some useful info out of them as well as I hope sharif will give me some input on that as well.

 

23 psi ! sure this is a 700whp car

i allso shoting for this, but i have 1 problem, the fuel system. i have the CJM stage 2, but everyone told me i have to get a twin fuel pump. my turbos are T3/T4 stage 3 from ultimate-racing turbo kit.

 

AAM makes a fuel pump setup here it is on Sharif's site

On pump gas, depending on the turbo system and supporting mods....16-18psi is about all she will take. With race fuel....the limits are much much higher. It's only a matter of time before true 800whp certified 350Z's are roaming the streets.

 

Sharif I have the greddy TT, I'm even modifying my HKS exhaust to 3"

 

sharif, what about water/alc injection? Could this also raise the boost potential?

 

Isn't 1.2 Bar about 17psi?

 

Water/Meth injection isnt a magic bullet, but its does allow for slightly leaner AF ratios, and a degree or two more timing...max. Probably good for another safe 20-30whp or so.

 

yes it's exactly 17.405 psi

 

Okay, I just wanted to verify. I saw a conversion chart and wanted to make sure it was right.

 

1.2 bar really does not say anything....its dependant on the snail pressurizing the air

1.2 bar on a K03 (stock turbo on an A4) is ALOT different than 1.2 bar from a GT42r

what kit are you running and what are your mods? That will give us a better idea as to how much boost you likely can run safely

 

Very good point. I assumed the poster was refering to the current crop of kits on the market....when making my statements about max boost pressure.

 

I hear ya - I assumed the same thing but just in case a newbie reads this or the thread is searched in the future

 

Its a Greddy TT kit and modifyed HKS exhast 3", Nismo HG, ARP main studs, L19 head studs, fule system, c2 cams, HKS limited addition boost cont., aris pistons, and eagle rods, ported and polished heads and intake.... i cant remmember what eles lol i just woke up and came to the office lol but i think thats it.

 

28psi on 1/2" studs and GT42R
