This lower torque will help protect the rods and the trans. Overall It should be one of the more reliable FI options, no FI is as reliable as NA but this would probably be the most reliable FI option.

The reason that the Stillen kit has been labeled as unreliable is not because of the power that it produces, but rather the design itself being flawed. This thread (Before Installing Stillen Supercharger) goes over the issues. Basically MAF before intercooler = bad.

I’m sure the unreliability is hyped up a bit since people are less likely to report good results than to bash it if they have a problem. But Bottom line.. there are better options.

Plus, the Stillen canned tune is garbage and makes it unreliable. If the OP is in California, which I assume he is if he's asking about CARB,, he would have to go with the Stillen tune because aftermarket tunes have been banned and will show up during testing. That's an automatic fail

Exactly! Thank you.

Most people trash the kit because it does not make a lot of power and requires a lot of modifications to the kit like A2A conversion to make some real power. And if your goal was power I’d recommend the topgunz rotrex kit (which I have myself)

The MAF location is a concern but on the carb tune it is accounted for in the tune and the boost levels and subsequent heat are much lower so the concern in this case is minimal.

Op is looking for a conservative safe setup to presumably add just a little over FBO NA levels and not push it. The stillen carb seems to fit the bill, at about 370-400whp. Most people want and expect more. It’s easy to get greedy or have unrealistic expectations and then the stillen falls short requiring you to spend a lot to fix it it to make closure to 500whp+ like most people really want to satisfy.

He didn’t mention budget or his DIY capabilities, but IAT relocation isn’t that hard, adding WMI isn’t difficult and would bring IAT down much closer to pre blower temps IAT was reading if he didn’t relocate. but on carb setup I don’t think it’s a huge deal.

But boost is addicting and that 370-400whp is going to feel slow real quick and he'll want to upgrade. Ask me how I know, or just look at my signature

That I agree with. The temptation is hard to overcome especially when its so close.

Nice sig. didn’t notice at first.

I got a topgunz rotrex sc at 11psi by 4500rpm flatlined to redline on E40, cjm return, Id1300, walbro 535, KB boost a pump, isr longtube header etc…. Guessing a solid 500AWHP. 1-2 pulls super hard. 3rd is fun, 4th is already boring lol.

Good thing about his kit is you can dial up the boost when you want more power. You have a lot of boost left
