Innovate (Sprintex) Supercharger Owners Topic

Two questions, 1 technical (maybe?) and 1 opinion.

Technical

Are the bolts that hold the pulley on the same M6 X 20 that hold the blower to the manifold?


Opinon

I want to run a smaller pulley and am undecided between the 70mm and 72.5mm. I've been leaning more towards the 72.5mm so I won't be running the supercharger at its maximum at all times. But I know with running the 70mm you get a decent bump in power. Those running either or have run both, suggestions?

What you are referring to is not the maximum. It is the continuous rating of the blower. Yes. You will go past the continuous rating with the 70 but only by a little. And that is at redline. How often are you going to be at redline? The blower should be able To operate at that continuous rating rpm for forever. If you daily your car it will be perfectly fine. If you track it. Maybe get the 72 but it shouldn't be a problem either way. There is only a couple hundred rpm difference.

at what rpm is the continuous rating?

Don't rail on me if I'm wrong, but I believe it is 15k rpm.

Thank you for wording it better. That's what I was referring to, but the way you said it is more accurate. Thanks for your input.

and what rpm is that on the motor? with a 70mm pulley

Here is a pic.
We had to taper the hole bigger to get the fitting we have locally in.

Is there a DIY somewhere for installing a boost gauge? I see you put it there but what fittings, hose, and other stuff did you use? Where did you wire the electrical for the boost gauge? Sorry if I'm a newbie with boost gauges.

Here is a DIY for the boost gauge option I went with.

This is where I get my E85:

22111 North Scottsdale Rd, Scottsdale

It's just a few miles north of the 101 on Scottsdale Rd.

I did a little math and it looks like the blower is getting pushed past the 15000 continious rating by about 550 rpm at the 7500 rpm shift point with the 70mm pulley.

so lowering the redline to to what rpm makes it even at 15000?

7234. If my numbers are right. I'll have to go back and make sure but it sounds right.

That sounds about right. You could either set a rev limited via EcuTek, I tend to shift around 7k-7.1k anyways though.

[Dustin]

I'll probably do the same. Have my shift light come on at 7k and shift shortly after that. Went ahead and ordered the 70mm pulley today. If we're only talking about the last couple hundred rpms in the rev range, I'm not gonna worry about it. @swift996 you went with the 72.5mm correct? How are you liking it?
