Innovate Motorsports Twin Screw Supercharger Kit for FR-S/BRZ

Me to, but I've seen plenty with it off as well. Honestly what I'm thinking is that everything fits, but when the engine is under heavy load it might be making contact. I have nothing to go on for that so please don't ask for proof. It's just that at least half of the pics have the bar off and I can't think of any other reason for this.

This applies to all FI kits, YES, it will throw off the tune.

You know how our stock ECU is sensitive to intake changes?... Well, when you go FI it is even more sensitive.

Question for those who have experience; I am really interested in this stage 1 sc as it seems it will be safe and easier to maintain than other FI, and also reasonably priced. My main concern is engine saftey. I don't want a lot more power, just a little more.

So to add an intercooler to the stage 1 would be about $1300.
1. I don't live in a super hot or freezing area,
2. I would only plan to take this to a track once in a while (most, once a month)
3. I'm only looking for a little more power,
4. Miles would be be less than 10k year

Am I still risking it if I don't have an intercooler.??

Thank you...

Good question and I know intake and oil temps are totally different things but would an engine oil cooler be a good idea with the stage 1 kit if we don't want to run the intercooler?

I will definately not be doing an cooling to begin with if I go with this kit from past experience with an uncooled roots supercharger. (I know... I've said this before but...) I made 280whp on a Jackson Racing SC without cooling using an 11psi sized pulley and 550 injectors.. stock fuel pump on a K Series 4 cylinder. In the heat of summer you could notice some loss of power, but it was still nicely quick. I also knew a guy with the same setup in Phoenix and he loved it and never complained of heat issues. To be fair, the K has an oil cooler (of sorts) cooled by engine coolant.

A twin screw has a naturally cooler air charge than a roots blower, so I'm not sure I'd ever need the cooling... and for a street car with light track time, you're probably good. It's great you can add it if you need it. I do think I'll add an oil cooler since this motor does not have one.

Doesn't stage 2 also have fuel upgrades?

at 5psi no car needs IC specially with a SC even a turbo could get away without IC at 5psi but ask the experts.

Really? An N/A motor that already runs hot, and you don't think track use should use an IC? That's nuts. You must be a very gentle driver.

I'll back this statement up. I'm running a roots (4th gen Eaton MP-90) on a 4.0 in an '07 Mustang, non-intercooled @10+ PSI. I have pretty much the same observations as above... power drops somewhat in the heat, but no damage done. If the tune is properly set up, as temperatures rise, timing is pulled to prevent detonation.

As stated above, twin screws create less heat. That combined with lower PSI, makes it a non-issue in my mind. Frequent track users may still want to opt for the intercooler though.

The cost differential between intercooled and non is pretty small. If you're going to do it, you might as well do it right IMO.

I'd assume the already high compression nature of this engine makes running without an intercooler that much less desirable. Sounds like knock city.

Not to be rude, but a K20 is a high compression 4 cylinder. I never had any issues with knock. Most people actually experience knock on their tune during winter due to dense air charge, not heat. Warmer air just makes you slower. Just trying to bring first hand experience to the discussion.

Sounds like you're just making assumptions, because people keep bringing up the compression issue and there still hasn't been anyone blow up the motor with proper tuning.

Its more likely that Innovate is going to properly tune it for the measly 5 psi and there isn't gonna be any knock issues come up.

[OrbitalEllipses]

This engine is higher compression, no?

In any case I did say assume, so I don't see why we must point out that I MUST be assuming.
