Hey I just did my first auto-x with my u-drive pully yesterday and leaving it in second gear was great the car actually responded when I punched it in the lower RPM range. Thank you for the great product Mike!!! NST FTW!!!

Got a pulley set from Garm the other day. Great quality. Very light. Put them in today. Couldnt feel a difference. Must be better for manual transmissions. Will have to drive the car a bit harder.

Can you explain why the CR Lite pulley is better suited for supercharged cars? Like will there be a issue if I use that pulley? I plan on getting a supercharger down the road and I don't want 2 pullies. If you could explain the difference between the CR Lite and the Underdrive, I think I can finally make a decision haha. Also I believe I read that the underdrive pulley is smaller than stock and since I have no A/C I will have to get a shorter belt. Is the CR Lite pulley the same diameter as stock?

The underdrive pulley is a little smaller, so it ends up spinning the water pump, alternator, A/C compressor, etc a bit slower (10% in the case of NST underdrive crank pulley). This is enough to free up a little bit of power and at the same time not affect the other functions. Unless your stereo or some other electrical app requires a lot of power, you won't feel the difference just because the pulleys are spinning a little slower. It's like changing your driving style to 10% less rpm...

The basic idea is that smaller and lighter needs less energy to spin (accelerating and decelerating), so your engine will feel more responsive.

You don't need a shorter belt, you just need to adjust the alternator on the groove, pull it a little to take the slack out of the belt after you install the pulley. At least that's what I did on mine and so far it's been working fine.

Fmicle do you have A/C? I think it's Barber that has the underdrive installed and had to change his belt. Would there be a draw back if I use the CR Lite w/o a supercharger? I would imagine not since I'm thinking all it is, is a pulley that is significantly lighter.

Yes, I do have A/C and just got back from a trip to L.A. (from San Jose), and I had the A/C on 90% of the time. I must add that the car performed excellently, exceeding my expectations in terms of acceleration and speed. And the gas mileage I got on the way there blew me away. I will refuel on Tuesday and post my results to this thread.

I wouldn't call it a "drawback", it's an improvement either way, it's just a slightly better improvement with the underdrive than with the "lite", if my understanding is correct.

The NST Underdrive Crank Pulley is intended for n/a or turbo applications. This pulley should not be used with a supercharger because it would lower PSI on such an application.

You can use the NST CR-Lite on n/a, turbo, or SC applications.

You can use the CR-Lite now and keep it installed once you install your supercharger.

Perfect. Just the answer I was looking for. Looking to purchase real soon.

All I can say is WOW...NST CR Lite Pulley

So I incorrectly thought my car was quite quick with the mods that I had installed, but after taking it out today for the first time with the NST CR-Lite pulley, I have to say I was sorely mistaken...

Now it's FAST... (O.K. excluding Garm...)

The crank pulley absolutely has changed everything...

The feeling that revving up first gear is going to blow up my engine is gone...It revs up nicely, and allows more time to prepare for second gear, which I felt was a trouble spot off the line before the pulley install...

Above 4000 RPM up to redline is just so much stronger, and more importantly smooth and effortless...The car is just nuts (my face literally switches between this and this ) now at 5-6000 RPM...

I'm actually glad I did this after all of my other mods; I didn't think there would be as much noticeable difference as compared to the postive feedback given by relatively stock guys doing this swap...

Cheers

LOVE THE PULLEYS LOW TO MID RANGE IS EXCELLENT. GREEEEAT PRODUCT MIKE AND THANKS AGAIN.

ozmdd · 09-01-2009, 06:49 PM

Well, this is a lot to try and sort through. Guess I'll just ask anyway: what is the potential downside (if any) to using the underdrive version rather than the CR Lite?

rhino5 · 09-08-2009, 05:43 PM

Just ordered, updates when received and installed.

rhino5 · 09-13-2009, 05:16 PM

Took almost exactly 45 minutes with electric impact ratchet. Had a friend throw it in 5th and hold the brakes while I torqued her down (actually had to jack the car up higher just to get the clearance and a proper angle for the torque wrench).

Noticed a slight difference in revs and a very noticeable difference while passing in 3rd. Made the investment for fuel economy more than anything (my daily commute is 35 miles of mixed driving with a heavy foot, getting 35 +/-2 mpg now. If the results impress me at the pump, I might consider the Alt and WP pulley.

Anyone have anything to comment on upgrading from solely crank pulley to the combined 3?

ozmdd · 09-13-2009, 05:48 PM

Yup. Got my u-drive pulley installed on Friday, and I think it was closer to 30 mins, but maybe 45. I was excited! Same thing; had to jack the car up a bit more to get really good torque leverage. Its about as easy as anything you do on a car. The impact wrench makes it easy. Hardest thing is loosening the alternator lower-bolt.

Love the improved response and definitely better power in mid-gears. Not a huge increase, nut definitely noticeable from the get-go. I think driving on the regular commute route will reveal more as I approach the same roads I drive every day. No argument about the bang-for-the-buck argument; it is worth it.

Told you these pulleys rock!!!

Yeah I thought that would be a good idea, so that in combo with a cai, and good exauhst it should make a reasonable bit of difference.

My next purchase is the larger sway bar from micro or NST if I can get a hold of them.

Any new NST Pulley owners out there?!
