k i'm setting my car up to have a 150 shot on it after heads and cam. i'll have S2 5.3 heads with 11:1 compression. i need to know a good nitrous cam that is fairly large so it will do well when the nitrous isn't engaged. thanks for the help.

 

How bout the F1 cam. 230/226 .591/.569 112 I ran 7.6@92 N/A with the cam and stock heads. Went 6.5@109 on a 150 shot. I belive the people who make this cam have a shop car that runs High 7's NA and high 5's on the juice in the 1/8th. LMK I have the cam for sale also if you are interested asking $350 for it.

what about a trade for my T1 and 50 bucks from me?

 

Sorry man I already replaced it with a solid roller. But thanks for the offer. LMK if you want it.

As a general rule, N2O will like more exhaust (duration and lift) and wider LSAs. However, if you're not builidng the motor for dedicated N2O use, then get a good N/A cam to benefit the most wide range of driving and just spray it

 

Ditto!

 

I built my setup like this for my TNT kit: The cam is a custom Comp grind (228/236 .571.602 111LSA) Heads are SII RMS 5.3's 2.02/1.57, double springed. ARP head STUDS, and all the other bolt-ons. As you can see, I think the nitrous will love my cam choice.

 

Thunder racing did me a custom n20 grind that works well on motor.

Its a 227/230 and it made 413 on motor with heads/cam combo. and its great for large doses of nitrous

 

needmoremoney: are you an M6 or A4 if your an A4 your trans aint gonna like that 111 lsa and i woudl think the nitrous would like a little wider lobe seperation as well

 

Yes I am an A4 (FLP level IV) and the car idles @ 900RPM's fine since i drilled the T.B to 3/16.

 

I like the X1 cam from MTI on 112 lobe. I`m tuned safely for the spray and still pulled good N/A numbers, check sig with what I have. When I sprayed She really got going. This cam sounds awsome! PM me your E-mail address and I can send you my dyno sheet on spray and bottle. MTI picked my cam! Jayson tuned it.

 

The Grand Am Cup cam on a lsa of 112 would be awesome: 239/251//570/570

 

that would be speedtek, we havent gotten the car into the 5's yet but it will be very soon, we are having some tuning probs with the new setup.

our old setup went a best of 6.4 @ 109 f1 cam, speedtek heads, NX dual maf kit 300, full stock weight, along with full wolfe suspension, and almost no ls1 edit tuning.

car made 680 rwhp/ 870rwtq also had out built tranny.


i have our SPI1 cam in my car only made 367 on the motor,
on 100 shot it made 488/ 512 on the 150 shot it made 537/668 those were both 10.0 a/f, so i have a little tuning to do that was through an a4 unlocked. motor has 128k miles on it.
