Alright, well we ran into a slight problem today on the dyno, we had a severe sputtering problem all day long that adversely affected our tuning. I later found that the spark plugs wires were bad and completely resolved the issue we had, too bad that was after the dyno tuning!
Anyways, through all of the stuttering it still managed 434 whp and 380 lb/ft of torque at about 25 psi on 110. Tune was very conservative due to the fact that RS motorsports wouldn't let me use their wideband with race gas! After solving the sputtering problem the car pulls much much harder. We have a pretty decent tune at 25 psi that I will be using for the shootout. Maybe when I get back we can play around with some higher boost levels ;) Off to the shootout baby! Chris |
Why not tell everyone of the other excitement?

Yeah it was an exciting night for us huh? After randomly driving to get a good tune, we stop by elite to bump up the boost and open the cutout. Well as we pull out of elite's parking lot I go for a second gear pull, which pulled extremely hard until the loud POP! I almost crapped my pants and shut it down. I hop out and someone points out that I am leaking pretty heavily.
Well as it turns out my drain plug for the T case worked itself out! The best part is that at the exact same time an intercooler pipe decided to blow off causing my car to shut down. Had I not pulled over for the intercooler pipe blow off the T case would have locked up and I would be screwed. It is unbelievable how lucky I got that nothing was damaged in the T case at all, and that the intercooler pipe blew off at the exact time so I would stop. So if you see a two block streak of tranny fluid on the street parallel to elite you know what it's from! What an interesting night, man oh man... Chris |
yeah, that sucked... But in the end, car is fine,and pulls very very very hard for 25psi.
|
i can verify that it pulls very hard. it scares me.
|
Very nice numbers especially being an AWD Dyno.
Congrats can't wait to see it at 30psi and a nice tune. :3gears: |
Gratz Chris!
|
Thats it?
|
So when are you going to dyno at Elite that way we can see where you stand against everyone else.
would that be about 468whp on Elite's Dyno? |
Chris could you post up your car setup?

Maybe Josh wants to enlighten everyone on his estimates for horsepower after we fixed the plug wires? Expect me to be on elite's dyno shortly after the shootout, assuming my tranny is in one piece ;) And the hell with 30 psi, we'll just jump to 35 and see if I can't get up to a respectable spot on that leader board! Chris |
Should have just dynoed at Elite in the first place. We actually let people use our wideband for some strange reason and we would have replaced the plugs after the first signs of misfire since that problem only happens about 95% of the time when you try to run high boost with leaded gas on used plugs.

Well my car only makes like 87 hp at the crank, so I was J/K.How's the spool and response with that extra .4 liter?
|
i thought it was kinda slow
|
jk :D
|
What's the advantage to running Teflon coated pistons? I've heard of ceramic coated pistsons and cryno treating pistons but never teflon coating.
|
Teflon just helps prevent scuffing on the skirts and reduces friction.
The plug wires were actually the problem on the dyno rather than the plugs, swapping the plugs wouldn't have changed it, the wires were pretty bad. The setup was far from perfect and a number of things could have been changed to improve the outcome, time and money right before the SO are limiting factors at this point. |
With the Eagle rods, did the ends require any resizing before use?
|
Since we were capping at 46lbs a min, and chris talked to a dsmlink guy that looked at his log and 'estimated' at 51lbs/min I would venture a guess of 450-475awhp right now.
And the problem was the wires, not the plugs. When he gets back, he'll throw in a maf-t and up it to 35psi or so on elites dyno. |
I was reading that also on dsmlink forums. (I'm the one that asked the question)
51lbs/min is impressive considering: 1G head 1G Cams 1G Intake Manifold I'm seeing 52lbs/min on pump gas with my car. But I'm reving to 8,000rpms how high is Chris Reving his car to? and it's creeps from 22psi at 7200rpms up to 25psi when I hit 8,000rpms. On Race Gas at 25psi - I was seeing 54lbs/min for my 456.7whp? And I'm running HKS 264/272s, and Magnus SMI. So gets some damn cams, and a sheet metal in that thing and let see some 57lbs/min |
I dunno, it was an estimate via my butt after riding in johns car. We are only running 25.3psi peak, its averaging around 23psi I would say. Spool-up is insanly fast and he is reving to 7500rpm right now. Once he does some head work/sheetmetal/cams this winter, it should really scoot!
On the dyno we were hitting 36lbs a minute or so. It would get to 42, then fall back, then go back to 40 and make peak power. I'll see if I can get some dyno graphs posted sometime soon. The car was missing the entire time, and still made good power. I wish we would of swapped plug wires at the dyno, would of saved time last night, but things always work out for the best. If the car would of been 'tuned' not last night, drain plug would of probably fell out somewhere in Wisconsin and he would of been SOL. Sometimes things happen for reasons.. |
so true..
congrats... and btw, Chris, you called? sorry i missed your call. whats up? _E |

I don't know about his car.
But we are basically running the same turbo but he has a .82 a/r And I know the difference in Airflow from 7500 - 8,000 is big. At about 7500rpms - most of the time I'm only at about 45lbs/min At 8,000rpms I'm at about 52lbs/min So all I got to say is DAMN - maybe he will hit 60lbs/min with Cams, And SMI. |
it must be something about that 7th bolt thing that is causing the problems with the transfer case!

to the pistons? no, not in Chris's case. 1G rods to 2G pistons or 1G rods to Wiesco's are in need of some machining/bushing.
|
Ross pistons also can require pin fitting to the rod on the small end. Wisecos are usually dead on.
|
I'm referring to the build quality of the Eagle rods. There have been people who have run into trouble with the Eagle 4G63 rods having imperfections which required possibly resizing them, as in the journals not being in spec from the factory.

Nope no problems with the rods, and Mike checked everything over himself 7 or so times to make sure lol!
Yeah with the MAS pinned I am not sure about actual airflow, basically the ECU is guessing at this point based on VE tables...Also revving the 8000 at this point is doable, but probably wouldn't yield much of a gain due to stock head/cams/intake manifold... We'll stick with 7500 and 25 psi for the SO, once I get back we'll see whats up :) Chris |
Chris, looks like you are heading in the right direction. Nice job on the 7bolt, hope you do well at the SO.
Does everybody have 400+ HP cars now? :bounce: Jim |
no, yours hasn't started yet. lol
|
I believe Chris has a larger turbo than you Brian if I can remember right. You have a gt35 right?
