Here is a quote from another forum I am on when someone made a comment about SRT-6s hitting 400whp with a few mods. I told them it has yet to be done on the stock SC without nitrous.

Anyone care to comment, I just dont see it happening.

 

not possible without nos and with the current supercharger and way she flows....

 

While I don't know what he may actually have done to his SRT I don't doubt it at all.
Milled and ported heads,
Injectors,
Cam,
Headers, and a dozen other little secrets like Chomemolidinum disulfide and Teflon. If you have the money you can get the horse power!
To say something isn't possible is the first mistake made which generally loses a racer money!

while I completely agree with you, a lot of us tuners have done some pretty heavy homework on the amount of air flow that the supercharger can handle under the most stressed conditions. I believe the car can do that HP, just the SC is the limiting factor...

 

I believe Vadim over at MBWorld had the most power out of any M112K.

2002 Mercedes Benz C32 - Evosport - Eurotuner Magazine

And he had every bolt on available including a custom intercooler that wasn't made available due to its lack of cooling capabilities beyond the stock unit.

 

not true as randy and i are the only two xfires at countyline or PBIR that we know of and we have been there a lot. ,,there is a couple of jeeps srt8 4 wheel dr. that runs the 1/8 in high 5's and the low 6's Randy and i ran 7.9to 8.1

 

Guys,

People keep saying that the factory supercharger is the limiting factor, why has no one created a custom intake that will accept a larger whipple or KB supercharger??

I hate to bring up some old stuff, but the article from the Thailand tuner had a larger whipple supercharger installed on a C32. The article was posted on the MB board and again here by me in late 2007 or early 2008. He had found away around the electronics and the magnetic clutch and installed the larger supercharger to keep up with the increased displacement from the 3.7L V6 he installed into the C32.

I know you can do anything for $$$$$, but if guys are willing to shell out $1200+ for mani's and $800 for a dual cai intake, I really think this is possible....and a cost effective mod....again this is based on everyone in the know saying the current supercharger is limiting (too small).

I could be way off base and full of crap, but it is a thought.

Not to ramble on too much more, but we do have the cooling mods down, not question, thanks to Woody and NeedsWings, a proper dual CAI, now we need a supercharger that can produce higher boost levels more efficiently without all of the excess heat...

just my $.02

Because the r&d, time, effort and money will never be offset with profit from such a tiny group of owners(srt6's) and an even smaller number of people willing to purchase.

I offered modified manifolds putting down similar numbers as the NW units for less than 1/2 the price and they didnt sell. So from a vendor perspective f--- it. Few are willing to shell out cash. Hell no ones even done cams yet. No one is near 400whp, and those who have claimed it have yet to show dyno sheets. 430 is a joke, dont get me wrong with enough $$$$$$$$$$$$$$ anything is possible but ya may as well buy another car at that point. Next best thing going is the turbo setup Jake is working on but we will see what it does in the real world(1/4 mi).

FWIW i do agree with you the next logical step is to mate a bigger/better supercharger up........but im not holding my breath on that one.

BTW, what ever happened with all that talk of torque converters? Shouldnt everyone be running mid 11's now?

 

That's mine except I'm in AZ. The right bolt on's will get you in the 11's, the right tuning will keep you there.

 

I think those numbers are very high. He was probably on a dynojet on race fuel or something. I dont think he ever had a 181 or 185 or a heat exchanger or anything. A trap speed of 111 and an et or 12.5? Jake (Loungn14) runs faster times at higher traps. I mean crap...I expect my car to be trapping at least 111 and thats in AZ on 91.

 

240, I know Jake @ Eurocharged has a torque converter on his C32, but because of the converter was seeing torque that was more than the TCU would allow. This would cause poor shifts and semi-limp mode. This is, in addition to poor track prep, the biggest reason his times didn't improve at track day a few weeks ago...

I don't think the torque converter from the C is actually the same on the SRT. I think I remember Jake and Wayne at Eurocharged saying it was the one that fits the E55. Either way, overcoming the TCU issue seems to be a must once HP/TQ gets above a certain level...when there are breakthroughs in the TCU I am sure you will see a lot more people a) consistently in the 11s and b) with torque converters.

I'm sure Jake (lougn14) wouldn't mind explaining to you the problem he was having...but then again his torque is waaaayy up there.

 

ya, too much torque causes trans to go to limp mode.....(tcu)

not fun...

We are working on a tcu software mod now, we already unlocked the tq mgmt settings on the ecu side...

 

At what tq level does this occur?

Great to see your working on a fix.
