I ran into this guy (freind of a freind) Who wants to buy my stock lower pulley for his '03 cobra. He says it is bigger then the '03 cobra pulley, and will add boost? Has anyone know if this is true? If the guy really wants to buy the stock pulley I'll sell it to him. Although I would think the ASP, or March would make a lower pulley for the cobra, like the pulley for the Lightnings?

 

Im taking a shot in the dark here but I was under the impression that they replace the upper pulley with ours?

 

Ya tell your buddy he needs an upper pulley because it is smaller.

why do a L pulley when you can get a smaller pulley then that?!?!?!?!?!

spin the hell out of that blower.

 

2.80 upper on a 03 =

Many cobra owners are noticing the boost dropping off in the upper RPMs with smaller pulleys due to belt slippage. The 2.93 and the 3.10 seem to be the current HOT ticket.

I think we need a better tensioner system. RT, didn't you come up with something? I'm sure us cobra owners would love to see what you did on your Lightning.

Yeah I got one for my L, I'm sure I could make one for the Cobra guys with no sweet. just bring one over and I'll design somthing to work.

 

How about some photos? Shouldn't be too difficult. Let the cat out of the bag! =)

 

they already have new lower pulley designs unfortunately i think they r quite pricey b/c u cant just change the lower pulley. the idler pulleys are too close. i know metco has a lower out. he just needs a stock lightning upper pulley. i put one on my brothers 03 and he went 12.21@ 116 on street tires and 85 degree and humid weather, hot with no cool down. he had a much better run goin and missed 4th and still ran a 12.24. it should go 12.0's. jlp chip, lightning pulley, and upr cold air! traction is definetely a big problem now.
