I'm going to need dyno sheet proof of that

 

it's at church, so he might pushing 450-470 at a dyno jet, that's sick for a SC already...
nice work John

 

I was tuned at Bisimoto Engineering and his Dynapack reads lower than Church's

 

On the current setup only since May and about 2500 hard miles. I always fill up with fresh gas when I take her out. I change the oil at 2-2.5 months regardless of how many miles because the car sits around a bit. I wouldn't track it to 8500rpm...more like 7200-7300 which puts me at 400rwhp.

 

Why wouldn't you track it to redline? It's not like you're stressing the valvetrain at 8500rpm.

 

...
good to know.. and sorry for my mistaken.

by they , what exhaust r u using?
because i am using 70MM TP and exhaust for my 10psi, and my tuner said, that i got some flow restrict, and it cause not making boost over 12 psi.( i have a asp 3.8 pulley)

thx

Leo

 

No. A better flowing exhaust will show less boost for that exact reason...less restriction means everything is flowing better and the pressure gets from the intake manifold, through the block, and out the back faster. A more restrictive exhaust yields higher boost pressure but less peak HP (but possibly a bit more torque).

Who's your tuner?

 

Evans-tuning tuned my car

here is my mods..
my 2007 s2000.
K-pro dual ecu
Vortech v3-sci
ASP racing 3.8 pulley that's about 12 psi.
1000 injectors
walbro fuel pump
sos 3 bar map sensor
t1r v3 single 70mm tp and cat back

stock header ,bone stock engine..

 

I run a 70mm test pipe and the stock exhaust. I haven't found an exhaust I like yet.

 

your still running the stock exhaust o man!!! so now your numbers are even more impressive. if you like the car the way it sounds now but don't mind a little little like 10% more noise then you might enjoy the invidia v4. i had that for over a year and it served its purpose for being 70mm and being almost as quiet as stock
