Dyno Results!!

[Zydis]

Had the car on the dyno this weekend. The first pull produced 283hp/275tq @ 20psi no tuning. The session ended with a best pull of 325hp/319tq @ 22psi tuned. All runs were on 94 pump gas. The car gained 42hp/44tq on 2psi and AFC tuning!!! Check my profile for all mods, but I have a 56 trim ball bearing Garrett turbo and stock engine internals that have 97k on them. Just want to get some feedback to see if this is where the car should be on pump, or can I get some more power. Can't wait to go to the track and fill'er up with some C-16. WOW.

I have seen cars with 50-trims pull 400 whp on pump gas, so you should be able to squeeze some more power out of the car.

What kept you from turning the boost up even more?

What kind of timing advance were you seeing at WOT?

What type of boost are 50trims running to get 400whp? Are they generating more hp/tq at the same boost (22psi)?

The shop did not want to go past the 22psi w/o c-16 and I had 1/2 tank of 94, so they would not mix.

Did not have my logger with me, but the hp/tq curves look like no timing retard was happening. The fuel pressure was set at 32psi due to 660 injectors. I feel I can turn up the FP and boost w/o any detonation.

I would be curious to know what kind of timing etc you were getting. I think you can get more out of it on pump gas, but thats easier said than done. I know what I made without tuning, so that's what I'm basing this off of. Nonetheless, 325 to the wheels is nothing to sneeze at on pump gas , but like I said, I think you can do alot better.

You didn't give enough information about your turbo to make an accurate opinion.

Please post the trims, both hot and cold side and the housings. My gut says your hot side is starting to choke.

Do you have the SBR GT-12 or the full garrett turbo? I saw that you have a garrett manifold? But that doesn't fit with the GT-12 (mitsu turbine housing).

You can count on 1 hand how many people are making 400hp on pump gas on a 50 trim. I can only think of one off the top of my head. Most people that do those types of numbers on a 50 trim are VERY good tuners with all the “right” supporting mods and most importantly they use a standalone. You just cant expect that your average guy off the street is going to be able to recreate that with a safc and a 2g MAS ESPECIALLY with no cams.

Especially considering that Garrett doesnt make exhaust manifolds for Mitsu cars or any other cars to my knowledge.

Zydis: Those are great first time numbers. I do have a few questions. Can you post the chart? I have a few friends that are going with standard GT56s I would like to see what effect the ball bearings have on spool. Did you log you’re a/f ratio on the runs? If so what was it? Did you try cooler plugs?

You say:

If you really want to prove us wrong: Call up Jegs and order 14in welds and 25in tall slicks, Go to the track and with a little practice hit your goal. Its that simple. The people that say its impossible or hard aren’t committed enough to go with the “right” solution. Hitting 11s on 17in street tires with a 45 series sidewall is next to impossible but if you go with slicks or a radial with plenty of contact patch and sidewall it becomes MUCH easier.

I think we both know that I meant a manifold FLANGED for a garrett turbine housing.

Keep in mind, there are a few different "56 trim" GT compressor wheels.

Here is the dyno graph. I just ran the car tonight with AFC settings from the dyno and the timing is down to 10-13 Knock is as high as 19. Looks like more power is to be had from the car with some tuning.

My booties are Nitto 555R drags 225/60/16. I just might give Jegs a call if they don't give me the traction

The turbo hits hard at 3500rpm. Boost is almost instantaneous. Even with LSD I get torque steer. Not much lost between shifts.

 

[DELTA_Rotary]

Those are good numbers. Put some high octane in and crank up the boost. I only dynoed 333whp with my L3R on 20psi pump but put down 393whp on 26psi and 110 octane.

You can run 11's in a FWD. I did it with slicks, eibachs, and some kyb adjustables. I think I am going to go with bigger slicks now.

Good luck and nice numbers!!

Richie from NJ recently ran 11.80@115 in FWD with a small 16G and slicks.

And Richie is going to be putting on the AGP RS49 on his car shortly.

This is some good info guys...
Zydis your numbers are very similar to what mine were. I did 321awhp/302tq on the dyno w.my GT-12. I was running ~19.5psi on 91octane.
Mods are all in my profile the way I did this. This was the first time I went and basically just bolted on 16psi and crap tuning ai did ~270whp. I was having many problems on the dyno however that were worrying me. For one my intake temp sensor blew the threads out of my TB elbow and boost immediately went from 19 to 13psi... The only way to fix this sorta was to thread lock it stick it in and put my T Bolt clamp holding the coupling (for the uip and elbow) slightly over the temp sensor to hold it in....needless to say it only jumped back up to about 17psi, so I turned her up again:laugh:

My the greddy type-s was starting to leak a little bit at this point so I tightened it up as much as it would go and didnt look back, didnt care to (I was really pissed off). So anyway we started tunign like this, I was being conservative considering what was happening, and I settled on a ~11.1 A/F ratio. I had my logger with me and was having some knock issues as well. I was getting about 12deg of timing steady, it hit hard and dropeed timing badly at abotu 3-3.5k which definetly had an effect on my TQ numbers (not to mention overall power/a/f curve). Anyhow I think its a pretty capapble turbo if 110+ is used. I think maybe another 30whp can be had out of my settup on pump, but thats not where it matters... I would be willing to bet this turbo can do BIG number on some c16 with/tools, dyno time and patience

damn, the torque starts dropping off early. pretty flat hp curve.
need to get some cams and an intake mani. and slicks; stupid traction.
