Are under drive pulleys worth the price for a daily driver? Since I can't get any more HP out of my NA I am looking at ways to more effectivley use the HP I have. I'm going to install a lighter exshaust and remove the rear seat. Under drive pulleys seem to be a good way to go but are they worth the price for a non-track car?

 

Yeah, they are crazy expensive for our cars. I paid 160.00 for the ones on my Mustang when i had it. I know www.autosportfl.com has them, and you can buy them individualy. It may be worth just doing the crankshaft pully so one does not have to drop a load on the whole kit.

 

track or not, some cars just have trouble with aftermarket pulleys

would be nice to know if there are known problems with 944's using aftermarket pulleys

you are talking about Lyndsey set right? they seem to be pretty cheap

Nope. Not worth it. PS does not draw much. A/C nothing when off so all you have left is the alternator. No point.

 

Do you run stock or underdrive pulleys on your race car? Are you required to do so by rules?

Isn't there a benefit, if for nothing else... the weight of the pulleys themselves?

 

I know the Broadfoot (AutosportFL) peices are lighter, but even if you did the Crank, both P/S pullies, and the Alt. It's only 7 hp freed up. A few lbs and a few ponies for $375.

 

the only pully I have is for the alternator.

No powersteering, no A/C. The pullies do need to be stock howver.

 

i remember reading somewhere (pelican i think) that pulley weight on the front of the engine should be related to flywheel weight on the back somehow...someone was looking at putting a 12lb single-mass flywheel on his 968 and they chewed him out because the pulleys would unbalance it or something.

might all just be BS but who knows.

 

That has more to do with the balance shafts

 

I didn't see the Lyndsey set. Much better price. Still would like to know if it is worth it.

 

I know on Neons and various other cars the UDP's are good. They free up HP. and the allow the engine to spin easier. If they were only maybe 100-200 they would definitly be worth it.

 

Obviously my posts go unnoticed here.....

375 (or whatever LR sells em for) for the set of 4 pullies. For 7 hp. And that may even have been on a 951 and not an N/A.

You make the call if it's worth it or not.

 

I say ever ounce of HP is worth it, Get them, I did

 

Hey Fast, Is your car done yet? would you mind PMing me about your NOS set up I have mine all set up and installed and would like to know what our running so we can compare notes

 

Nitrous isnt setup yet, Still finishing the install of the motor, SHould be running very soon, Once I get it running I will be swapping in a LR Mafterburner setup and tuning, The nitrous kit I have waiting to be instlled is a NOS single fogger wet setup, 50-100hp adjustable, I dont want to install it untill im done breaking in the engine this way I wont be tempted to use it LOL. My idea for the nitrous setup is to T off the end of the fuel rail where the check ball is then run the nitrous sil. off that and a fuel pressure sensor off that too. For timing I have a MSD digitial SCI plus with built in nitrous retard if needed. I Will keep everyone posted,.
