No real evidence to support that, but my theory says I prefer the Metco for that reason.

 

So we’re on the same page then..

 

I’m not. I don’t believe belt slip is beneficial in any sense of the word. All boost mods should have a pinned or keyed crank pulley. Having that takes the lower half out of this equation. As far as the blower snout and bearings go.... I think that increased belt tension trying to reduce slip is not a good thing all the time (not just off and on the throttle) and allowing it to slip as a kind of poor mans blower stress relief is (I’m just going to say it... sorry) halfass. I say go Griptec or put a Liten on it. I will not run a screeching Metco with the additional idlers and tensioners to try to get it to work right.

That was actually the right analogy. Again, poor mans version or not, being that it’s a version would mean it’s still sort of better than not doing it at all isn’t it?

Not debating you here at all either. I was about to order the geiptec, then my usually over thinking came about and this thought popped in my head. Now I’m wondering do I just bite the bullet and go litens up front.

 

Or just get a Litens pulley and be done with it. That’s the route I’m going, it sucks because it’s much more expensive but in the long run it’s a better choice all around.

 

Litens is a great pulley if youre one and done. I plan on changing pulleys for race tunes e85 etc

 

You can always get the 2.72 pulley and just have a conservative 93 tune and then load a race tune for the track. I suppose some people want to push the stock blower harder than what a 2.72 can offer.

 

I think the Litens 2.72 is questionable for reliability. I am trying to find some solid info online to clear up my confusion. Is Hellraiser with Litens logo a real Litens made pulley? The reason i ask is my stock Litens is stamped "made in Germany" 2.72 is stamped made in "Canada" seems a little odd. I do have a good reason for my concern. Just not aware of who i should call to get info.

Interesting, I didn’t know that... I wonder if anyone could chime in on this? Maybe Litens has a manufacturer in Canada?

 

What can I help you with SIR

 

Thank you for the info. I sent a PM to Paul Georges last week but i have not heard back from him. I thought i could speed things up a little sending it straight to him. Now that i read the link you sent maybe he is only involved in testing.

 

Sorry I did not receive a PM, I respond quickly to questions and inquires

 

So is this accurate: people are seeing 780 at the wheels (give or take) with just a pulley swap and tune? Someone on here have personal experience with the Hellraiser / Litens?

 

A 2.85 with 93 octane is 740-750 ish. Delete your cats about 770

 

Here is dyno graph of tune day on my M6 with a Litens 2.85 on pump 93. Stock verse 2.85 with ID1050x
Love it!!

Thanks for posting. What was the reason for changing the injectors? Was the tune particularly aggressive or something? Perhaps others are leaving out the injector swap, but most to the Hellraiser installs and mentions about seem to be just the pulley and tune, right?

 

Forgot, M6’s will dyno higher. I’m talking auto

 

It was a proven combo for many and recommended by tuner and I got a good buy on them so ran with it. Also have a JLT CAI, 180 tstat. It’s better to have a bit to much injector then not enough

 

Here was yesterdays best run, red light trying to get jump on guy next door but got smoked regardless lol. M6

What kind of DA are you in and who did your tune? MPH seems a bit low

 

HHP Tune, it could be tweaked for more, did 786 on the dyno tune day

2nd dyno day also saw 10-11 deg hotter and 17% higher humidity. 781 Is prob on the low side.

 

It felt like 3000 lol, we all got baked!! Car was hot as hell too, 150 IAT even pushing it through the lanes with hood open. Was doing run after run, about 15 passes in 4 hours. Smelled clutch last 2 runs. Have 1200 RXT HD to install soon as I get a DS

 

I guess it's that IAT that's the killer. I ran 100mph in the 1/8th yesterday in 2650 DA with just CAI and canned diablo tune. My IAT was only in the 130's though.

 

If its clutching both ways somone installed it using an impact gun and most likely damaged it
