Today me and my meckanic found out that the rotors in my S5 car are 10lbs ???

I guess my old meckanic that did the engine rebuild ripped me off.

My ? is , what will be the power difference with S4 low comp (9.4) rotors in my mega streetported 89GXL ?

WIll it rev not as high ? or make less top end power ? Last not as long exc ?


Also will I better be able to use Nitrous with the lower compression rotors?

 

Yes you can use nitrous. There will be a decent power drop Id suspect.

 

So thiers going to be a noticable Rev and power difference between 9.4 compression and 9.7? How much do you think?

 

Probably 10-15bhp? Maybe more maybe less. But I definately wouldnt take a engine w/ s4 rotors to 9k like some of the s5 dudes do.

 

why what do you think would happen over the S5 ones?
