hi all ..
im planing to install an APS TT kit on my 350z with 2.5" test pipe and 2.5" exhaust system , APS plenum.. so,,
1. what is the rwhp can i get with 8 psi and 98 octane?
2. is the 8 psi is the safe boost for standard engine at these octane ?
3. should i put 2,5" test pipes and exhaust or 3.5" test pipes and 3" exhaust to the best performance ?

1st do you have a unichip tuner near you?

1) approximately 400 rwhp

2) yes

3) see first statement. The 3.5 TP's and 3" exhaust will have you boosting at 10-12 psi. So you need a tuner with a dyno to set your boost for stock block.

yes i have an APS dealer near to me .. so he can tune my car

but i need the safe side boost 8 psi .. so can i use the 3.5" tp and the 3" exhaust or not or i will get a lose in the power and using the 2.5 tp and exhaust is better ..

dude 98 octane!!! On the street pumps?Lucky..I would say on 98 your good for 460whp.

telcom

yes 98 octane .. we have 3 kinds of octanes 93 , 95 , and 98 ..
but you didnt tell me about the test pipes can i use the 3.5" and 3" exhaust with out loosing power at 8 psi ..

the 2.5" set up will be fine for a stock motor.The 3.5" set up will make more boost and is made for built motors mostly..I made 530WHP on 100 octane with the 2.5"set up.

The 2.5" setup is more than enough for a stock block. It will flow to mid 500's. You can get the big pipes and exhaust if you like, but realistically, it won't make a difference other than sound/appearance. Your tuner will be the determining factor on what HP you will have. If you want more, just have him up the boost.

I think the comparison of gasoline overseas has been discussed. 98 oct that he is referring to would be comparable to our premium (92/93 oct).

i really hate arguing and convincing people...i went ahead and did a little questioning here and there..our 98oct is not like your 92/93 octane...our 98octane is actualy 98 octane..
thank you

I think 98 ron is similar to our 93 oct. With that I wish we had 98 oct.

The 3.5 and 3" exhaust will have you boost much higher with the stock tune from aps. The last car I saw that had that exhaust setup they had to turn down the boost because of it. The unichip will have to be tuned for that exhaust system right after install. I wouldn't drive the car before the tune. You can't go wrong with either exhaust system.

That right. Its the same in Europe. 98 Oct here is measured in Ron and in the States its R+M/2 so our 98 is the equivalent of your 94.
