Well since the GM bash in OH the weather was about 30 degrees colder, I had somewhat of a better tune, and also running the meth injection for the first time so that kinda threw things off a bit

I'm still running the 75mm pulley, only getting 91% duty cycle, about 20.6PSI

The dyno was on a dynapack dyno thats the kind that your wheel hubs bolt to, no rollers

Laid down 282.7hp and 254.8 tq, keep in mind this is on stock timing and at 11.3AFR, so theres some room for improvement

I'm strongly considering moving to the 80mm as many have stated to do so for a car thats running a stock motor.

Some good things, NOT one touch of knock at all in the entire run and IAT2 never exceeded 135, weather was in the 60s today with light rain

slowswap

Play with the timing already!!!!!!!!!

Congrats dude. I've been waiting to see some decent numbers. Got any videos of it at all?

hmmm i would of expected alot more... but im sure your just getting into it as your tune sounds a little "rough around the edges"

when you say stock timing do you mean stock stage 2 timing or STOCK timing... i assume your running a stage 2 tune with only the injector table modified for 60's? ohh and anything over 80% idc is not good...

ralliartist

What's up with the low numbers from the tvs cars? Go hit the track up, I'm more curious about trap speeds than I am your dyno numbers.

hungryhip-ccp

iTrader: (2)

ehh its all in the tune... i mean you can squeeze another 40hp out of that set-up with a aggressve tune

slowswap

Yeah, from how he described it, I'd say you're right.

ralliartist

I'm still wanting to know his trap speeds at the track. Dyno numbers don't really mean much of anything to me, unless he has some before and after numbers.

shoot for a 11.9 richening to a 11.7 after 6000rpm and it will ease up on the injectors a tad! 11.3 is way conservative

R&C_rallySS

Congrats Matt!!

I see 300hp in your future...

Plastic

282.7hp seems kind of disheartning, almost makes me want to give up on a future tvs and just put the car on the bottle after the motor is built.

But then again dyno #'s are pointless, every dyno is different. But like ralliartist practically said, track times are what matters

ralliartist

well, I dunno how good of a driver he is. Considering that no one has went 12's with the tvs, it doesn't look promising. I'm just curious about the trap speed. If he traps well over 110mph, then I would be happy if I was him.

With a trap speed that high, he SHOULD run 12's easily though, but once again, why hasn't anyone else?

JimzSS

I ran 104.5mph in my ss/sc...any hp guesses? I am getting dynoed and tuned the 25th. Sorry for the thread jack. Those are promising #s.

Tennpenn83

thought there was a tvs somewhere that went only 13.9 but @ 110. easy to say no traction... but 110mph trap speed should be good for high 12's

Blown 4-banger

This is exactly why I'm not doing the TVS. There have been many M62 cars running like 18 psi, that have made more than 282 whp.

slowswap

But there's a difference, he can swap pulleys, make a more aggressive tune and surpass what the M62 will do. And the M62's making those numbers are far more modded then what this guy has I'm sure.

The tune is far from aggressive I know theres alot to be picked up in it. Ive added alot of new things so its going to take some time to set up.

I'm sure theres M62 cars running 282whp but I can almost promise you none of them are doing it under 134 IAT2 at 7000rpm

i have a fujita intake, 60s and zzp header, downpipe and exhaust all 3 inch and leaking

im sure with a head and cams id pick up a bunch too and run the 75mm more effectively

Sorry to disappoint but the track isnt happening until i get rid of this 9100 credit card debt because i need axles clutch and drag radials thats not happening anytime soon. Maybe in a year or two

zinner

When I did my dyno test with the M62 with a 2.8 I only got about 10 extra hp when I bumped up the timing. You might be able to get it over 300hp.

im optimistic i can do it (more timing) even with the 75mm on, im not sure what the big reason is why ppl feel they can make better power with the 80mm on

Deathscythe

I don't remember reading anything about your cooling mods in the past, but I'm sure you've heard all about that by now. I'm getting almost everything possible for cooling, so I can benefit from more timing in the long run. I have the 80mm on mine, so you might be dealing with the chokepoint on the intake side of the head because of the added airflow.

Timmay

if he or anyone else traps 110 mph and gets a 13 second pass, that just means they had a crappy launch. wheel spin, hop, etc

Steven Flit

Who cares about DR, and axles. Roll out of it, and see how you trap. I drop the clutch at 5k, but then again I have full motor mounts.

Problem with doing that is as soon as I shift into 2nd at 7000rpm I spin the **** out of 2nd, if you let off the throttle then your wasting your time even being there.

A 13.9 at 110mph with gross 60fts would mean absolutely nothing to me

ralliartist

It would mean that you suck at driving to me. LOL. I've seen as gross as 14.4@118mph. Stupid SRT owner. LOL.

JANNETTYRACING

Next time your on the dyno turn the meth off you will see some nice gains, contrary to popular belief LOL.

Zach06CobaltSC

The above will do one of two things.

Prove that you don't have a tune for methanol injection.

Or it will create so much knock that you will cry. I am guessing the 1st since your tune isn't aggressive. However, the iat2's will be much higher. If you add more timing, the methanol really comes in handy.

I hope to hell that's what he is talking about, because if I ever run out of methanol and im at full boost, it will be a sad sad day for my car.
