Stock 2003 Z06 plot below for comparison.

 

That's it, come on man, turn the boost up, you should be running 14psi at the lowest for a V8. Many honda's on here have more HP than that, take advantage of the extra 4 cyclinders, and turn the boost up. Still good power for a domestic at 9psi, if you run 16psi-20psi you should be well over 600hp, and with a 76mm turbo on the 331, it's not even being strand/used yet.

 

for real hahah stock bottom end b16's and gsr's have thrown down higher hp numbers! haha just joshin

 

It's odd how you went domestic talk on the displacement and injector size .

 

if its a stock block im sure he aint gunna go much higher than it is now. I see its a 331 but i mean the actual block itself.

maybe he's after more than just peak HP..it's making 250 wtq barely off idle...and the torque 'curve' if you want to call it that looks like a ******* square wave..something us honda guys will never enjoy

 

stock ZO6 has only 314 at the wheels? Whats the new ones have?

Only 314...

2003 Z06 = 405 @ the crank minus 20% drivetrain loss for manual transmission ~ 324 RWHP. But that depends on the specific vehicle and weather that day. We've dyno'd stock Z06's which range from 297 RWHP to 327 RWHP on our Mustang Dyno (P1Auto's dyno is a Mustang too, so it'll read slightly lower than a DynoJet).

The new C6 Z06's easily hit 420 RWHP with an advertised HP of 505 at the crank.

Those numbers are really low... I always thought the C5 Z06's put down close to 340-350 WHP considering that the LS1/LS6 tech handbook shows several LS6's baseline numbers being in that range. DynoJet numbers mostly.

20% driveline loss for manual is crazy... My Camry's auto loses about 22-24%... These Mustang dyno's read exceptionally low; hard to go by any dyno numbers these days except for before & after comparison purposes.

Really, I dont think so. Thats about right. My friends LS1 trans am dynoed 270whp at our elevation (3.5k) in stock form, with a few mods 307whp, which included, K&N, removed cats, WS6 throttle body, retuned ecu. I'm pretty sure that was on a mustang dyno too. Granted it was an auto too, but there are also alot more drivetrain components on a rwd; drive shaft, u-joints, rear end, then axles. I still thought it was 17% or less.

whats his timing like?? thats a little low for a 331 with a hellion kit.

is it a stock block with a stroke kit or like a D.S.S. shortie??

I'm interested in knowing how long that nonWC t5 is going to last behind that engine, those things suck even worse than WC t5's.

 

Looks good. Has the car been on the scales?

 

i'm just waiting for the follow up post of how his block split down the middle.

keeping it under 6k is smart...but, that's just way too much on a non-mexican block.

lots of power left in it though...shitty e-cam is killing him. even an f-cam would be better...... and trickflow upper and lower...even if it's the r-box its crap....spyder or similar would be awesome to see on there...and they're cheap....supervictor and intakeelbows.com elbow and you're set.

 

mustang dyno people, not a dynojet.

Remember this.

i hear the stock blocks are good to ~700-750.

i am currently looking for a fox body, or a efi lst/lt1 to boost.

good to see im not the only one on HT that like turbo v8 enough to build one

wow...um...no.. a stock 302, non-mexican roller is good for about 500whp...in small spurts...below 6000rpm. now, a mexican 302 might be good for around that...but not in large doses...although some have done it and stuck, but...it's just a fine line between cracked block and not.

if you do a fox body, do a 351w based engine, or an aftermarket block....or a bb. 351w based engines are cheap as hell to build (what i have) and you can get upwards of 450ci out of them. right now i'm going to start building up a 433w with a prosystems carb (only the best) on a vic. with some good aussie heads that are worked and a big shot on top with a c4/stall/brake. i'll be running mid 9's for the price it cost a honda to break into the 11's. and will still get 20+mpg

I want to do the same thing. except it would be easier to smog a honda.

 

mustangs are fun to tune... i havent got to do a turbo stang yet, just a few big vortec blown mustangs. ****, 650 on pump shouldnt be a problem for that setup

thanks for the info

i want to run 10s on street tires (M&H DOT bias ply )

im not brand loyal so ill take whatever chasis i can get my hands on cheap.
good luck with your car,
id like to see a video when it does run

 

a4block it!!!!!dynamic c4 also or at least a tremmec

 

tremec's are cool and all...but expensive. a t56 alone won't cut it with the 10spline input...at all. it couldn't even handle 618whp for us. you'll have to go viper spect t56 with a 26spline and steel forks.....or...tko600 or a modded tko900 would be nice...but, you'll still be giving up so much over a nice brake'd c4. you can get a c4 and 8" or so for fairly cheap

and 10's on radials can be done with a stock block, no problem. but.......go 351w and shoot for 9's on radials...also, not much of a problem.

90/10, 50/50, sfc, lowers and uppers, tq box bracing, and a few other small suspension things...and a mild 351 build will easily get you 10's on pump

buy a fox body.......then you have no smog worries.

 

One day I'm going to inject & turbo my 67 firebird, numbers like this would be fun. I know my mom's 02 WS6 is a blast to drive, so a boosted oldskool muscle car would be ****. Eventually I want to do some FI on a v8 just for fun.

I know I should poke my head outside of HT for this, but what sort of ecu mods do you do for a moostang, or does a larger MAF do the trick? The only one I know much about is boostang w/megasquirt.


btw your pix load like old people expletive

 

Nice work Jack, im sure Tony was going nuts over this one.

bah, the only aussie heads worth a **** are the aussie cleveland heads, you building a clevor outta that w?

I've seen several non-texmex low nickel production 302 blocks in the mid 600's. The blocks can handle it if prepped right, just dont shoot gobs of nitrous at the same time. If I remember correctly that's what that one guy was doing exactly in those famous pics of his block split completely in half.
