most rwhp on a stock 3.8 auto?

tigerfan2771 · June 28th, 2008, 09:14 PM

hey guys what is the MOST rwhp that can be seen on a stock 3.8 block with an automatic transmission? i would like to see 230rwhp, but im being told that 220rwhp is the max. anyway here are the mods that i have done/ planning to do:

k&n air intake
65mm halfshafted throttle body
ported upper
ported lower with egr delete and imrc removed
cnc ported cylinder heads with comp springs for .600 lift
harland sharp 1.73 roller rockers
pushrods
comp 224/224 billet cam with a 112lsa and .548 lift
arp head studs
bbk shorty headers
off-road h-pipe
flowmaster dual exhaust
dyno tune
asp 25% underdrive pulley
screamin demon coil pack
livewires
autolite spark plugs

this is everything i think can be done performance wise without using long tubes. if im missing something please let me know. so is 230rwhp reasonable with these mods? ill also be looking to extend my redline and shift points over 6000 rpm and ill be using 93 octane. i was debating on a boost cooler but i dont know if it will help an n/a car like mine.

tigerfan2771 · June 28th, 2008, 09:27 PM

DeMello · June 28th, 2008, 09:27 PM

I would say 230 is possible, weird cam choice for an n/a 3.8L.

wow just was over at v6 power and this is the same post!
I could see 230 but look into longtubes if u want hp numbers, but i wouldnt buy them if u already have shorties.

joparrett · June 29th, 2008, 01:40 AM

I always heard 300hp???

you're probably right. I've heard the 300 number from somewhere, though.

What about running nitrous? 3.8 split sport stock is like ~185 hp at the wheels, getting a 125 shot of nitrous would put you at ~300 hp. 125 shot of nitrous is generally accepted as the maximum limit to run it safely.

V6 Stalker · June 29th, 2008, 04:14 AM

not on a v6. i wouldn't go over an 85 shot on our cars.

swap over to longtubes and a windstar intake and add an aluminum driveshaft and you could see probly another ~10rwhp easy

Avaric3 · June 29th, 2008, 09:53 AM

o ya, the limits of the 3.8l are pretty much about 220-240rwhp n/a. if you wanna go 4.2l or 4.3l than your limits more like 240-265. im givin a broad range like that cuz all things can effect the final output such as the tune, the cam choice, auto or manual, etc

also i dont see gears or t-lock in your mod list? explain

ESG-642T · June 29th, 2008, 11:54 AM

264/280 is the highest known N/A rwhp.

You can obviously get more out of F/C induction.

supermachone · June 29th, 2008, 12:10 PM

well if you are going to tune it on a dyno, you will find out there

I've read several times of people running 125 shot safely with no problems.

ESG-642T · June 29th, 2008, 02:18 PM

Safe: 100shot
Super safe: 85shot
Pushing it: 125shot

why is that a weird cam choice? hiposilver is running that cam and pushing for 300rwhp n/a. ill be doing forced induction hopefully by the end of the year. i just wanna get all that i can out of it for now.
