I think if going with a bigger/more efficient heat exchanger makes you feel better or make a difference (I haven't seen documentation so I can't say for sure) there is no danger in that mod. You're not changing anything to add pressure or stress to the system.

We will be test out our high boost kit soon and will see what the limitations and issue are with the kit as is. If the heat exchanger proves to be an issue we will include one with the new kit or offer it as an upgrade.

Hey Mark,
There is actually I thread on here where it showed more WHP with the frozenboost heat exchanger, it was one of the euro guys VLAD!
He did runs without it and runs with it, he had gains thought he power band .

Hmmm maybe when I swap injectors/UPREV Sensors I will add this as well. More cool never hurts :)

Interesting, do you have more info. about the new kit ?

I can't find it :(

Why not offer it with the SI impeller ($365) and the 8 psi pulley? 2-3 psi gain at the same rpms. What do you gain from changing out an 8 psi pulley for a 9 psi pulley? 12-15 hp?

yeah this is not what I was hoping for haha.

I was thinking an upgraded blower/E85 compatible fuel pump/injectors at a minimum

You think I should go back with HFC? i do have a 3" a am exhaust. I don't know what to do!!

Thanks man! I guess I will try some HFC. Recommend any? I have the AAM 3" exhaust that helped a lot. When I changed the HFC to test pipes it felt different .

he's saying with the stillen supercharger kit, it works better with more back pressure, so going from test pipes to HFC probably won't make much difference, the 3" exhaust won't be helping with this either, but remember, don't judge your dyno numbers vs other peoples, every dyno is different and will read different figures.

the only way you can truely measure your gains is on the same dyno and roughly the same temperature during your runs, you would need to do some before and after, but again the money you spend to change parts, probably isn't worth the HP you MAY gain, there is no guarantee.

infact you'd be better off;

adding oil cooler if your temps are too hot
adding larger heat exchanger if your temps are too hot
adding water/meth kit to either aid as a safety or increase timing
adding fuel pump/injectors to suit E85 and re-tune if it's available in your area

they will yield better results then changing your exhaust without wasting money.

Hey Mark ,
Post 34 :).

I would take a look into motion labs thread also I know everyone's numbers are different but they tunes your kit with the impeller upgrade . Say they made 484?

We have not really considered the impeller upgrade as it would no longer be a simple bolt on upgrade for the current STILLEN Kit. We like to make products that will be safe, reliable, and are pretty straight forward. If we feel there is enough of a demand for a more extreme (call it stage 3 or 4) upgrade with a different compressor wheel and completely different fuel system we will look into it.

You should go back to stock cats if you are running the STILLEN Kit. I would highly recommend stock cats. High flow cats are more likely to blow out and you will still only make a little more power over test pipes. Stock cats will get you the best power.

Thanks Mike! I will be going over this with our tuner and engineer.

so it still isnt going to do 500 out of the box?
