50 Trim Dyno Results...torque monster?

[ItsStockOfficer]

I dyno'ed my car. The setup is a PTE 50 trim w/ 76 trim turbine, 272's, magnus manifold, race core.

I got a ungodly amoutn of torque, for some reason I'm not sure about. Cam alignment appears to be on. My MBC was a home depot special made the ngiht ebfore, so it hade large spikes, but not ones that aligned with peak torque, and torque was maintained

All in all, im satisfied. This dyno was on 2/3 c12 and 1/3 91. My best 1/4 mile to date is 11.77@121 on a 4/5 c12 mix.

Here's 3 images. My best with a/f ratio, my worst to show my torque curve, since the rest all have a/f, and my chart for my best pass. You will also note that between 62 and 64 my HP starts to go back UP despite my falling boost, and that Im make over 380 hp over 7k with only 23 psi....I need to hold 26 to 8 grand....

Numbers look good. Props Its been a while since Ive posted looks like everyone is doing Ok.

Thanks, I was hoping for something north of 400, bt I suppose I got close enough to keep me happy for now.

Hey - Is this a everyday driver? I was thinking about getting the 272's instead of the 264/272- Is it a harsh idle- I'm running it with a green - Its a 99x and a everday driver- Would you suggest the 272's???? I hope to pull some numbers like you- I'm at 295 now with a 16g

Yeah, it's my only car and the cams are straight 272's. they're perfectly fine for a daily. I recomend them.

 

[NewB2dsm]

just so you know to get those number to a dynojet readings there is a 17% correction factor. The dyno dynamics reads the lowest of ALL dynos but is the BEST for tuning the car.

So on a dyno jet or a mustang dyno you should expect around 464awhp.

if you dont belive me do some reaseach on the dyno dynamics dyno. Nice numbers man

 

[kpt4321]

I wouldn't use an exact number like 17% as the correction factor, as it varies all over the place. However, he surely is making somewhere around 450 whp in terms of dynojet numbers.

Well done!

i can agree but also disagree since the dyno dynamics dyno i use, the owner said he got the 17% from the rep that comes to keep the dyno up to date and load new stuff and for first time users teach the owner a few tricks. So i would think that if a rep from dyno dynamics says 17% is a pretty safe number it has to be close. But your right its not 100% correct but gives you an idea. None the less great numbers!

 

[ItsStockOfficer]

It's hard to say really, this is the same dynamic dyno that Vishnu uses, model and all, and dyno dynamics claims 2% consistency between their dynos, but the dynos read more like 6-10% apart. This dyno is still lower then a dynojet....but any correction factor is +- 5% in my book, it's impossible to nail down.

Neways, thanks guys! I still have plenty to work out, my ignition timing is terrible, but with just an afc it's hard to do much.

 

[Wicked99GSX]

Hey the numbers are not really all that big a deal- Get the 1/4 mile slips - Anywhere around 400awhp is great - I can't wait until all my parts are ready to go on- What upsets me is that on a 16g I made 295AWHP and now people are telling me that with the green I will probably only make 350- I was hoping for 400-

 

[nanokpsi]

Nice numbers What kind of ignition advance are you seeing? I wonder if you are having trouble holding boost because of the wg or if you are flowing on the limits of the turbo. Hmmmm Intenal or external?

Wicked 99- You are going to need about +-25 psi with cams on 2g hardware (head/intake mani) for 400awhp. A little less if you are on the 1g head/intake mani.

 

[Wicked99GSX]

I wanna run at 22psi - I have the 1g intake mani and tb- No 1g head and I'm looking for some 272/272 cams- A 1g head will be too expensive of a job- I can't do that myself-

 

[nanokpsi]

22 psi with cams *should* put you around 42lb/min on the 2g stuff. I don't think the 1g mani will be a big gain if it isn't port mached to the head. The mismatch could certainly create some turbulence in the flow. Depending on tuning/timing that should be anywhere from 350-370 awhp.

 

[Wicked99GSX]

How about with a venom intake manifold on the 2g-???

Im seeing between 26 and 33 degrees advance. I think boost falls becuase my MBC sucks actually, it was a home depot special i made the night before, spiked like a mammajamma. I got it to hold 24 psi till redline but it wad to hit 32 psi during the spike to do so and it broke up.

I wanna run at 22psi - I have the 1g intake mani and tb- No 1g head and I'm looking for some 272/272 cams- A 1g head will be too expensive of a job- I can't do that myself-

Run as much boost as you can, why limit yourself? Is this 400awhp goal for race gas or pump gas? On race gas it won't be hard but you'll wanna run 25 psi or so. no reason not too.

 

[Wicked99GSX]

I wanna hit 400 on 94 octane and I don't wanna run 25psi because I don't want to do any damage - So a 1g intake mani will hurt more than it will help- Is it an expensive job to machine the head to fit it up-

 

[RDS]

Firsty nice figures, i run the same turbo on my car so thats incouraging The only thing that ive noticed is the air fuel ratio is around 12.5:1 for the duration of the power run. Do you not think that is a little on the lean side? It would explain why you made such good power figures anyway. Please correct me if im wrong but I would expect to see AFR's at 20psi+ boost in the region of 11.5:1 and lower. Not knocking the figs just curious about the AFR

 

[Blk_99gst]

I think the rule of thumb would be to shoot for 11.5:1 on pump gas, and then 12:1 or 12.5:1 on leaded race gas.

 

[ItsStockOfficer]

The wideband was slightly odd due to exhaust leaks, for instance I only got 4 counts of knock at 13:1 which is frankly impossible when measuered accurately at my o2 housing. its seems to be .4-.7 off.

 

[btrux06]

stock block?

 

[Staytuned]

You brought this thread back from the dead to ask that? Try PM'ing the guy instead.

 

[DSMTurboEclipse]

Well now that its back, congrats ItsStockOfficer, awesome numbers and I love your car.

 

[btrux06]

ya so what. im sure there were lots of others like me wondering if it was done on stock block .

 

[Staytuned]

So send him a PM, problem solved. No need to bring back 5 month old thread.

 

[btrux06]

better to have it in the thread so everyone else that reads through here wondering if he had engine internals or just stock block would no too. stop argueing now and well wait and see.
