SLP 402 numbers
 

Here is the mods:
Iron block
JE pistons (11.3 comp)
Eagle rods 6.125
Eagle Crank 4"
Comp Cams 232/242 598/609 112+2
Patriot Stage 3
LS6 intake
BBK 80mm
85MAF
28# inj

Ok and the numbers:
First run is with stock heads could not wait to put the motor together with the patriots. 461hp/476tq
Second run with same mods just with the cut out open 485/494
Two weeks later the third run which was 505/502 thats with the patriot heads and the cut out open.
Fourth run 516/517 run took place with the cut out open and some tunning with HP tuners. Most of the tunning was with the AF ratio. But there you go I will have the dyno slip posted soon. Just wanted to throw that out to you guys and see what you think...

I take it these are engine dyno numbers, not rear wheel?

if thats rear wheel, i'm sold !!

i hope not. if that is engine #'s i would be sick.

It sounds like it is rear wheel since he's running with open cut outs, if it was an engine dyno he'd most likely be running open headers anyways.

sounds nice, post some graphs and more specs on the driveline. Also whats with the 28# injectors? that thing needs more than a 28 pounder.

sounds potent...good numbers. That cam looks almost like the g5x2 specs.

how is the tq staying so close to the hp. with all of these 40x combos it seems like the tq is a little lower than the hp. just my observation. any thoughts?

Sorry guys it was on a Dynojet 224X dyno the drivetrain is a 6spd, 4:10 setup, and the motor with the exhaust closed was making some sad numbers with the patriot heads and all it only put about 492/476 but that is threw a flowmaster cat back. The dyno sheet should be up today.

Damn good #'s man esp. through 4.10's !!!

i'm with Brandon man a set of 42# injectors & 90/90 on top would be insane right there :devil:

peace

those numbers sound excellent. are they SAE?

Mike you are the only one i seen post an slp 402 dyno numbers good deal u know im over seas now but its ok mo money mo parts mo power!!!! But any way cant wait to see it at the track and i know somthing coming later but i wont tell!!! Well my car should be done by the time i get R.R so i will come by to blow up your dyno LOL going big now im adding nitrous afr's, T-70, an 12bolt hey by the way umm smoke kenny bell and when u do leave some for me!!! and post the vid see u soon man and sorry i dident get a chance to come by i had 3 days to get ready but its ok 2 more years an im done last thing tell shawn an kevin i said whats up joes car looks good an tell juan i said takito taco bell!!!!

like brandon and bad95 said, slap a fast 90mm intake and throttle body and some bigger injectors on that beast. i bet youll gain at least 20 more horsepower with the 90/90. i would think the 28# injectors would be maxed out now, for peace of mind i would put some 36# in there

I said this because the numbers are almost unbelievable. 460 rwhp through stock heads? Then 515rwhp with Patriots, small cam, and a LS6 intake? I've seen cars with AFR 225's, bigger cam, and a FAST 90mm make a bit less than that with the same cubes. Not doubting the numbers, just stating why I said that.:)

I built a 408ci for a customer awhile back that had stock, 241 LS1 castings on the motor. It made 470rwhp/470rwtq through a LS6 intake, 1 3/4 Hooker headers/y-pipe, and all the normal bolt-ons. It really isn't that unbelieveable in my opinion.

Nice #s!

Wow, I didn't have any clue that it could be so easy. Seems that for the longest time 408's struggled to hit 500rwhp. I know most are knocking down over 520 average now, but I wonder what was so hard 6 months to a year ago?

I Know mike and he dont bullsht he works hard on his car and others he took mine in two days put my motor in and i waited 4 months befor i had to get my car from anohter shop that just took his sweet azz time and piss me off i had all the parts within in a month and waited three more for nothing an he did it in two days and it looks like it came from the factory if you are near killeen check him out sunshine is cool so i know his numbers are not bs but facts he has nothing to prove but to kenny bell himself mustang boy

Damn, that took some work.:D

My 402 from scoggin dickey made 475 hp and 575 tq this weekend so i think those numbers are great i was hoping for over 500 hp but the torque was not expected but great to have

Nice numbers fellas!
