i dyno'd my 2002 ws6 tonight 6 speed
modifications: mahle forged short block
prc 2.5 heads -milled 30ths
tsp magic stick cam shaft
ls6 intake with stock throttle body
30 lb ford svo fuel injectors
pacesetter lts
ram power grip HD clutch
stock rear end

the car dyno'd tonight 440.9 rwh with torque at 406.1
so what you think about these numbers?
dyno sheet attached

 

pretty good, those are the same heads im looking at getting.

what kinda exhaust are you running?

looks like you could of ran it up another 200-300 rpms, and might of gained a higher peak #..... its also hard to read the a/f, kinda looks like its at 12.5 though towards the end, mgiht be a few more poneis if it were closer to 13 or low 13's. good deal though, bad *** to have a 440 rwhp all motor beast!

 

Nice!!!

 

Sound very damn good to me!! Nice job!!!!!!

 

Looks like the correction is in STD...makes it a tad higher. Not much though. Excellent #s either way.

 

Looks like ya need a ported TB , may get ya over 450

 

Nem rossz, kiraly...

 

Good numbers, you need to lean that thing out a touch and twist it on up there to 6800 or so

 

i'm running the pacesetter long tube headers with loud mouth exhausted without cat -
i no i no it to raspy & loud but my guys in the shop like it so much - so i'm going to leave it - so far no police ... yet !

 

I agree...

 

how much are those heads milled and how much flycutting was required - i wouldn't think you could mill .030 and run an MS3

 

that number was allright, id like to see what it did sae corrected.we did a car with the same exact setup and did like 435-440rwhp with the old tsp torquer cam .589 on a sze correction, i would think that ms3 would of went a little higher.

 

my heads were milled 30ths & it's 5.3 liter heads-- i have mahle forged pistons with -2 cc valve relief and i used 6.125 H beam rods. i don't have a problem with valve clearance - because i already had 2,000 miles on the engine & it was still running great
i also am posting my air flow ratio print out- i will try to get the ported tb & lean it out just a little bit - then i will check the dyno again.

 

Forged pistons have 2cc valve reliefs probably.

 

whats your CR?

 

Great results man! Get a TB from Bo!! I guess maybe those PRC heads do work

 

Expected higher sorry!!

 

Do you plan on spraying? i would only assume so since you said you have a forged short block...

 

would like to see it in SAE also. Still good numbers. No pulley either? Looks real good.

 

Should be higher than 440 rwhp. With the PRC 2.5s only giving you a gain of about 20 rwhp over cam only cars with the MS3 and 10 bolt, they aren't very impressive. It's probably just the tune though. Take Gomer's advice, lean it out a little and twist it up to about 6,800.
