Thread: What amount of KR is acceptable?

i have my gauge set at like 5.0 degrees and i often see 2.0 and also dont worry. I wish I saw .2 at the most!

Two tenths of a degree is better terminology however a twentieth of a degree is the same amount lol Ok thanks guys, I'll change the settings on the lights to go off a 1.0 on one and 2.0 on the other. I won't get concerned unless I see both of them go off. I've got mild cam, headers, ported valve bowls on the heads and a 3.2 pulley btw. Showing about 18.5 on the injector pulse width and 10.5 psi of boost so I think it's pretty safe.

yeah sounds like you'll be just fine LOL hows that thing run with the cam and pulley? i always wondered how my car woulda turned out if i woulda went through with camming it :/

and not that it matters a whole bunch, but im pretty sure 1/20 (one twentieth) = 0.05 while 2/10(two tenths) = 0.2

Your right my bad. The car is running great! The Xtreme energy cam is a stage 1 type cam but you can tell its cammed at idle for sure. The 105 springs allow for higher rpm's and it's tuned with 6250 shift points. The higher rpms is a noticeable difference when your used to the factory 5800. I started off with a 3.3 pulley and it was much quicker but I was only getting 9.5 psi of boost and zero KR so I tried a 3.2. With the 3.2 I'm getting 10.5 psi of boost and just a tad of KR here and there so I'm maxed out for now. I am considering e85 and bigger injectors next because e85 is available all around where I live and I've heard it's good for another 20 to 30hp with a tune.

ive heard E-85 is the way to go if you can get a good tune for it.

and as your car sits, i think you are right where you wanna be with pulley size and KR.

Yes I've read on here from a few guys that e85 really is a good way to go. Right now its almost a buck less per gallon in Michigan too! I know that the car will get less mpg's but it about evens out with the cheaper cost at the moment at least.
