hey guys,
im looking for a ncie turbo to use on my street car. I dont plan on useing race gas all the time. We have 94 octane here so thats what he have to work with. What are you guys running for rwhp on pump gas what turbo? what port? and hows your spool time? lets say when do you hit 10-12psi? thanks guys! I just dynoed my ported engine with a 60trim and layed down 350rwhp and 270Tq. I want more

at 17 psi on a stock port motor i made 427rwhp.

i should be around 475 with my t61 and 20 psi now

 

what's your dyno look like? got any more detailed specs on your turbo?

 

yeah hey i shouldve posted more specs. Its a T4 that has been rebuilt so i am not sure all teh internals now. It has a .96 a/r with a 60mm front wheel. 350rwhp was @ 13psi. My tuner didnt want to go higher. He felt that the octane wasnt there. My other friend has bought a Super T70 off ssautochrome on ebay and @ 11psi on a slightly smaller port made 380rwhp and 320Tq hes getting full boost @ 3800. I am getting full boost at about 3300. Im running 4 x 720cc injectors

NYT you running 20psi on pump gas?

 

93 octane

 

intense
when do u guys figure you are running out of octane? do u tune till it gives a little then back off a bit? what size injectors are your running? I am guess bigger injectors and mroe fuel would do nothing if the octane is not there?

 

p.s what are the specs on your turbo nyt ?

 

<--- Pump Gas / Blow Through Holley.

 

generall 93 octane is on the limit around 22 psi in a rotary (from my experience).

i just tune to 11:1 and use safe timing (13advance/10split @ 20psi).

 

i had a gt40 50 trim that was too small and couldnt provide the boost i needed up top, now i use a pt61 with to4s cover and .96 a/r p trim turbine.

 

I hit 413rwhp at 1.1bar with my RX6 turbo. Running 100 octane pump gas.

 

NYT is certainly breaking the conventions of how much boost on pump gas. Steve Kan told me 17 psi on 93, when he tuned my car. Most Forum experts say 17-18psi (maybe they mean 91 Octane, but I doubt it).

Maybe I will follow my Wolf3D brother into 20 psi land, we got Sunoco 94 up here in Canada

 

I dont know many people running over 18psi on pump gas, 94 is not a huge difference from 93.. seems like you are really pushing your motor and what the gas can withstand for a few ponies...

 

bastard =] the sunoco near me only has 93 =[ and only single handle per pump. i hate that ****. i fill up on 93 from the exxon near work most of the time.. havent had a problem with their gas..

 

ive done it for years? i had a street ported fd with a to4s, ran 20 psi all the time. fun fun fun.

and i beat the **** out of my car also. did a few 3-4 gear pulls today on the way to work.. boostn7 runs same thing. read hos post "10.8? on pump gas blah blah" hes running stupid fast on it.

 

stock port 13BT or RE?

 

stock s5 13bt

 

wow 427rwhp is pretty freakin good for a stock port S5 @ 17psi

 

i switched to the pt61 though and am running 20 psi throughout the entire rev range now. i will dyno again soon. expect some serious numbers =]

 

As my daily setting, I run 1 bar which made 380 whp on the dyno (while running 110) so it is probably actually a bit more than that.

 

some of you guys are lucky to have 100 octane at the pumps

 

if i had 100 octane at the pumps.. it'd be 30psi all day =[

 

^ Let's say you have a safe tune to 17 psi on pump 94.

Are there any guidlines as to how many more psi of boost you can run and degrees of timing you can add with 100 Octane.

I can get it at the pump here

 

its all in the tuning... 25 would be safe on a full tank of 100 provided the tuning was good and nothing else in the motor lets go =] you gotta realize thats a lot of power =]

 

Water injection.
