Today i put my truck up on the dyno for a dyno day at a local shop, found some kinks that i got fixed and well it was worth every second of time.

first pull made 428hp/434trq @ 10.32 psi

found a boost leak at the carb hat to throttle body contact, fixed that and then went for it again,

first pull made 535hp/589trq @ 15.8 psi

pulled some timing on the BTM box, and richened it up on the FMU and went for one last pull

made 560hp/608trq @ 16.05 psi with a nice 11.8: afr then let out at 4800 because i saw 12.8: afr's so i let out of it.

here is what it has:

engine:
318 5.2 stock cubic inch
EQ non ported heads with 2.020/1.625 ss valves
206 210 .480 .500 112 lsa comp cams
fully ported stock barrel intake
fully ported stock throttle body
9.3:1 compression

turbo system:
72mm garrett .84 a/r turbine t4
OBX truck headers flipped
3 inch crossover pipe
4 inch thick front mount
al 3 inch IC piping
hks 44mm gate
tial 50mm BOV

ignition:
crane 6 box
crane BTM box
crane dizzy
crane coil
crane 2 step controller

fuel system:
walbro 400lph in tank pump
92 fuel rails
-6an feed line
3/8ths return line
stock injectors
adjustable FMU
vortech blower carb hat with aux 60lbs injectors kick in under boost

stock trans
spec stage 3 clutch
stock rear end
3.90 stock gearing

this was on 91 octane, 1.21 SAE correction, i live in denver colorado.
462.507 uncorrected if any body is wondering.

was wondering if this is some kind of record or are there guys making this kind of power from a single turbo? didnt expect to make that kind of power! :mullet:

Damn nice numbers. I've heard that the stock bottom end is way stronger then most give it credit for though.

yes stock internals, when i pulled the top end off to do the new heads the cylinders still had very noticable cross hatching, almost like it was redone, but the owner before me said its the stock motor never been out of the truck which means it has 170,000 miles on it.

i didnt put a dial bore gauge down in one to double check the bore size but the pistons seemed stock to me.

when my tax return comes in i will be getting injectors and having it tuned on E85 on 14 psi.

is there any way to run a 2 or 3 bar map sensor? im maxing mine out of course but when it hits 17 psi it starts to spit and pop and i know its the map going nuts.

You need to ditch the FMU and aux injectors and go SCT with larger injectors and a 2bar map. I believe SCTs limit is 2bar, so you'd need to limit your boost to keep a clean tune. Then you can actually get it tuned in right and not go lean on the top end.

I made 592rwhp with 18psi from a Paxton and a set of 24lbers, on a stock bottom end. Duner has run 10's with an FMU and 24lbers. It's doable, especially with a turbo.

I'm not buying either thats 408 boosted #'s and your a 318? Im 360 stock bore with P.I.E. dyno tune @ 7 psi putting down my number's with no cooler and a rear mount 68? Chris told me for around ever lb of boost I go up I might see another 30hp but the amt of Hp drops off as it go's up in boost.

He's running more than double the boost you are, with a larger turbo. If you throw 16psi at yours, you'll be making 550+rwhp. No guarantees for how long, but it'll make the power. :D

I think your little 68mm turbo has got your ass plugged up... For example, I went from a small turbine wheeled TC76 to a larger S400SX3-75 (75mm compressor) and on 2# less boost, I picked up 10MPH at the track, still short shifting 1-2-3 gears.

Congrats dude, enjoy for as long as she holds together, cause at that level, I would guess its not long from now it'll meet its demise.

NO! His truck isn't a bondo unibody! ROFLMFAO

i understand you guys dont believe me, i wouldnt believe this shit either!!!!
i wanted to see 380 thats what my goal was, but i kept cranking up the boost and it just wont die!!!

so to prove this shit is for real you want me to take a picture of the injectors in the truck i mean i can take a nice quick video of the truck and go over everything!


the trans has never been out of the truck along with the motor has never been out according to the previous owner when i bought it. i never intended on making this kind of power and i can assure you the dyno is correct and the stuff i said is 100% bullshit free!

what do you guys want me to do to prove this? tell me ill do it!
i shit my self when i saw the 500 mark had been broken, even the guys at the dyno freaked the fuck out!

ill post a video of it also.

dakotanash- yes i am just waiting for it to let go, the whole drivetrain will give up the ghost one of these days, but if it lived through 4 dyno pulls of over 500 wheel then all i can do is wait, beat on it, and find out eventually when the time is now for it to all let go, i will be honest im not easy on this poor thing, the track opens this april, i WILL be launching it off the 2 step on drag radials at 3300 rpm. :)

@ misfit- i will post the video as soon as i get home and chop it up there was a few other cars on the video before mine. but you will see this thing in action tonight!

yes, once my tax return gets here im going to 60#ers and having the guys that dynod it they are an sct tuning shop they said it prolly has a good 5% power in it if switched fully to E85. i want to safely run 520 wheel i know it will last for a little while.

who makes a 2 bar map for these? or do i wire in a GM 2 bar?

Trans is rated at 300ft/lbs, it may live a little while. Typically a manual will hold up to quite a bit more than rated if not abused. I'm at least 150ft/lbs over in my truck and have been for a long time.

I lost a ring and land on a roots blown 3.9 @ 12psi (modified eaton m90), and two @ 14psi turbo'd (twin '03-05 WRX turbos). Roots non-intercooled + h20/meth 11:1 93pg, Turbo a/a intercooled + h20/meth 11.3:1 93pg. Both 50/50 h20:meth and light on the timing. Any measuring I've done says that the 318 and 239 pistons are the same. I'm well-aware that unusual circumstances can yield unusual results. I've also witnessed some pretty freak results from factory components, such as a bone stock LS1 long-block surviving an entire hard season @ 16psi on pump gas. I would bet, however, that this sb isn't going to last long. I'd take the steps needed to get forged assembly ready for when it happens. At minimum, forged pistons.

He's got some miles on it, the ring gaps have opened up I'm sure. The 5.9 magnum bottom end will take 600+hp, the 5.2 shouldn't be much different.

And the LS motors will also make a ton of power on the stock bottom ends before grenading, an LS1 running 16PSI and living doesn't surprise me.

yes stock trans and i would assume stock clutch, i got it bone stock and have not done a clutch yet, im sorry to make it seem like a total pile of shit but facts are facts and i cant say anything but what i have done and thats the turbo system and top end. other than that i have to assume its all stock cuz it was a stock truck when i bought it.

I guess it could be done, however it won't last very long I give it 2-3 passes and Boom! Someone will be putting a bucket with all the little parts in his bed as the tow it away..

as far as the map goes hell if i fucking know, i have been running around on 8 psi for a year now with no issues so maybe there is a power enrichment table that goes with rpm that is doing something i have no idea, my dyno paper shows it at 16.05 psi that is with a stock map sensor.

i dont care how long it lasts, its the fact that i made 560 on a stock bottom end 318 is the cool part, and that it made over 500 wheel for 4 pulls!

if it goes tomorrow so what? if it goes at the track so what? its still the fact that it took 4 pulls at over 500 wheel and didnt show one sign of any issues other than the 13:1 afr at the end of the pull.

i bet i get at least 2 or 3 good runs and maybe one or two good 2 step runs before it goes, i dont expect it to live very long, like i said my goal was 380 but that didnt happen lol

ill get it tuned on E85 and see how long i can make it live it it goes ill post the carnage and then i guess its time for a decent stroker to go in it.

I had no issues with the stock map when I ran the Paxton, and I was running 10-15psi for probably 70k miles.

I mean it can be done so that the MAP doesnt freak out but typically you have to run a check valve or keep the MAP from seeing boost. I was hoping to hear the OP's solution to this other than "How the fuck do I know" :shrug:

I was running 5psi and it shut down when it got warmed up and hit 3-4 psi ???? Had to do a Duner Mod to Map to get it to run. So I'm still smelling 1053hp here....
