Stillen supercharger long term reports

brucelidat · 04-15-2015, 06:27 PM

I already have LTHs on the car so it would be extra cost to put the stock cats back one if I did the kit, though I sort of want to be quieter anyway.

Oh ok I can understand that. You should call Mark, he's a good guy.

I"m trying to get all the info I can about various options so I can plan what to do once without having to go back and change things too much and also to not spend any extra money unnecessarily.

JWillis72 · 04-15-2015, 06:50 PM

Mark, is it enough WHP to make it worth going back to stock cats?

Anyone see thread on MYG37 about the poor guy that lost his motor on a custom tune from Stillen?

"It was a stock kit with GTR injectors tuned at stillen. I got it tuned there for reliability, The engine had 29,000 miles on it, got 3,000 out of the supercharger."

That sucks but we all play with fire boosting a NA motor. Sometimes you get burned. Every dyno pull made on my car I'm nervous it might let go.

I hear yea man, Guess he said it leaned out and tossed a rod.

Are there any independent customer dynos to confirm this claim of lower power with headers/TPs?

There are several customers who have proven this. I don't think I have the dyno sheets, but several reputable forum members have proven you lose 10-20 whp when going away from stock cats.

It has nothing to do with the flow. You have to understand the valve timing of the VQ37 and how VVEL works. We only have so much control of the valve timing and overlap. There is still some valve overlap that lets some of the boost escape into the exhaust during the intake cycle. The backpressure from the Cats actually helps keep some of the boost in the cylinder which makes more power (though headers and test pipes are more efficient at moving the exhaust gases, the loss in boost pressure in the cylinders results in less power).

It is usually a ~20 whp difference (I have seen as little as 12 whp from HFC's over test pipes). I don't have any dyno sheets from someone running long tube headers with the kit. That might end up being a wash because of how much more efficient long tubes can be. I don't have a lot of experience with the long tubes on a VQ37 (stupid CARB) so I can't say for sure what the results would be.

I did see that. Hoping we can get more info so we can figure out what happened. I've never seen a motor get blown from standard kit with no crazy mods. Only thing different on that car are the GTR 570cc injectors (I think that's right) VS the normal 600cc injectors. There are always other potential causes for lean conditions (not saying any of these actually happened). Someone could have put non 91 octane gas in which could cause that issue, but the knock sensors should have pulled timing pretty fast, Could have been a vacuum leak post MAF + pre blower, etc.

I have never seen a Rod Thrown from lean conditions. Usually it has to do with oiling or over revving. I am trying to work with him to help figure out what happened.

^^^ Lean will burn a piston or ring. It must have been a crappy stock rod. Happens.

Team Stillen, sent you a PM. Having issues with my set up.

mikey1600 · 04-16-2015, 02:49 PM

Still love to see some E85 results, I was gunna pull the pin couple months ago but ended up needing the funds for other stuff, so didn't get to do it

One thing I found out is this owner bought a Salvage G37. The car was a bit jacked up before the kit went on. I wouldn't be surprised if that contributed to it.

Yes his car was a salvaged title, but he did beat the crap out of it here in San Diego. He did just drive across the country to Maryland where it blew, it could be because of the climate difference between here and there. Who knows it seems like he's intent on selling the kit and just staying N/A now.

The climate really shouldn't have had anything to do with it throwing a rod. You can consult other tuners, but you'd be hard pressed to find any that will say a lean condition will cause a rod to get thrown. That is usually due to over revving (from a miss-shift, removal of rev limiter/fuel cut, etc). If he blew a ring landing or piston ring I might say that a lean condition was the culprit.
