I have tried both, and then some on this SC

Methenol inj. > Stage 4. Better results and a little bit cheaper

 

Numbers please. Did you dyno it? 1/4 mile times? More info.

 

stillen stage 4 usually makes around 300 or so, maybe a bit more depending on the setup. its a very clean factory looking system that makes the car a little more fun.

 

+ 1 Jeremy, seen alot of 300-312whp Stillen SC dyno numbers.

As many know, I have pretty much exhausted all options dealing with this E62 Eaton type stillen SC. We have tried severall sizes of custom pullies up to 13psi., different injector combinations, custom cams, blower porting & polishing, meth/water injection, different header/exhaust combos, etc, (pretty much everything but NOS) ever since this positive displacement SC came out for these cars. Trying to extract much power out of these SC'ers is like pulling teeth I can definately give you a bigger list of things that does NOT work, rather than a list of things that did work .

The most power I have seen on a stock motor is 343whp (DynoJet) numbers. Cams were good for about 10-12 of that whp and about 10 more was extracted from adding meth/H20 injection which let us run a little more timing and saw some lower temperatures. On the 2 different stage 4 (out of the bxx) Stillen upgrades we have done, I only saw 6-8whp gains over a stage 3.

As I have stated many times before, with this Stillen SC you pretty much got what you got. Sure you can beat yourself up trying to get up to a true 340-350whp, but that will be your limit (if you are lucky) or 410whp on a fully built motor. The peak efeciency of this blower is 60% at best and it stops making usable boost at about 9psi. Trying to spin this blower anything north of 8.75-9psi the blower will either start to cavitate or will start making much more heat than it is worth thus negating any real meaningfull gains.

You can't beat this SC for its sound, maintance, response, etc. but don't kill yourself trying to get more power out of this finiky blower. It seems to dislike most mods that you through at it, and the mods that do work on it, it has to be tuned for.

 

You mentioned the almighty equalizer - NOS... Has ANYONE tried pairing up the Stillen SC with a 100 shot on a built block? Bad idea? I'm just figuring that in order to fight heat and gain power where the Stillen falls flat, this may be the only real option? Maybe not? Thoughts?

 

Nitrous!! thats where its at, we are doing a nice nitrous/SC combo built motor as we speak...

 

^^^
You looking at a roots or cent. style blower??? Please do tell

 

LOL.... hahaha. I knew that question was comming. I will just leave that up to Mr.Tibbs and PF. That whole NOS thing seems to be his teritory.

 

Scott, clear your PM box.....

 

Ummm, ok.

 

Are you serious?? I really wouldn't have guessed. Wouldnt the Methanol set up be unsafe being that at my stage 3 the car has topped off its fuel flow and running lean as it is? Adding more power without increasing fuel flow can end up being a problem.... Or at least, thats how I figure it?

 

sounds bada$$

 

I have tried several things on a stage 1 kit with positive results. I have gained a lot of knowledge from this and have some ideas to make some big power. I plan to upgrade to a stage 4 over the winter with a small amount of Nitrous added to the mix and see what it can do on a stock block. If I see some good gains a set of SC cams will be added by next summer.

 

YOU'RE STILL ALIVE?!?

 

Keep me informed on that!

 

So I'm getting the stillen is very limited vibe. Is there a better way to go in terms of a SC

 

depends on what you wanna do. i love mine for autox

 

Get a vortech. 1000x better than stillen. There's a full upgraded t-trim kit in the classifieds as I speak.

 

so it appears you been searching... and this is the thread you came up with? you should have found alot more that told you to run away from stillen and keep running

 

almost forgot about this asshat.....
