The simple fact of the matter, (stockysnail you're right) is that the 335 makes too much air and power for the motor. I've had VERY reputable tuners tell me this. I'm pretty sure sprintex wouldn't even recommend it.
Stay away from that blower unless you're comfortably sitting on $50k and can afford to constantly be fixing pistons and holes. Not worth the extra power IMO. Just go turbo. Or run water meth. If you're looking for more than 315hp, sprintex IS NOT the solution. Quote:

I have some track and non-track video clips on my build thread if you'd like to check them out. I'm not trying to toot my own horn, but my exhaust setup on the track with the supercharger at full whine is the best sounding one I've heard. I let someone else drive it so I know from a spectators standpoint as you'll see in the videos. I've also had more compliments than I can count on how people have really loved the sound of my car on the street, autox, and at the track.

Power is power whether it comes from a supercharger or a turbocharger. Both are pushing more air into the engine. One isn't safer to run that the other. Anything over 300-325 WHP, S/C or turbo, and you're asking for trouble unless you build your engine. Yes, the extra power is delivered differently (S/C power curve is more linear) between the two but it matter not. Unless I'm missing something? Can you explain how 315+ WHP with a S/C is any less safe than 315+ WHP with a turbo? |

Turbo lag is what I'm talking about. You are at full boost in the green zone as opposed to being at full boost below 2k. Unless you think that stock internals can handle 9-11psi at 1.5k. By all means, post a vid. But do it with YOUR car.

Isn't that what the bypass valve does though? Doesn't it release some PSI at low RPM? I thought I read that somewhere about the Sprintex

I think it's open at full boost. Does something to keep the unit cool. Quite frankly, I've never been too sure though. I'm pretty sure it doesn't do any wastegating.

I have noooo clue where I read it but I thought that's what I read. Was why a lot of people have trouble getting boost prior to 3k because it's all to do with the vacuum differential blah blah. But I read so much about these cars so I can't remember where I saw it.

A 'tune' for an axle back, as opposed to stock, wouldn't make your car run any different. An axle back is behind all parts of the engine/exhaust that would show any performance gains. It would be mainly for sound. I've had the N1 at full catless on my Sprintex setup. Don't do it. Here's a few reasons why. It's fucking loud. With stock everything else, it's okay. But as soon as you add the supercharger and turn out to be chasing power, you'll swap the header and front pipe for a catless setup. Next thing you know, you can't hear yourself think in 6th gear cruising on the highway. I was going to say another reason, but I think I've summed it up enough. If you're still curious, I've put up enough videos.

As far as I know it's on full boost at full throttle no matter what rpm as the bypass valve is based on throttle %, and boost can't be modulated like in a turbo. I'm far from an expert so don't take my word for it.

I'm getting oil residue near the pulley on the snout. I'm using a 69mm pulley. Should I be concerned? I have the supercharger off right now anything I should check?
Also is this the normal position for everything on the bypass valve? Last edited by brianhj; 05-14-2016 at 02:07 PM. |

Just check your supercharger oil level at least once a month with it leaking from the snout. Bypass valve seems to look fine to me.
