hey guys just doing some research on cam before i rebuild my motor, being that i got a stand alone efi i can make this thing rev so if i need to buzz to 7000 grand to make it to the end of the track i can just need to be sure that the cam i pick will still make power i see lots of them drop off at 6200 so i thought this one might work 236/242 .556/.576 lsa 113 let me know what you guys think or might work .also i will be using afr's rev kit.

i dont think any cam is going to have much power past 6500 due to stock heads...

If you are serious about making power up that high go with a custom cam from someone like AI or Bret. Also why did you go aftermarket on the injection if only looking to rev to 7000rpms, the stock pcm can do that, granted it only goes to 7200 but that is above the 7000 you are talking about.

Oddly enough you will not find a lot of truely custom cams at 113lsa for NA use, granted that is a spec that should be the result of other specs not one specifically aimed for but still most of the "wide" cams are meant to let the average dummy buy too big a cam and then not be pissed about bad drivability, downside is signifigant midrange torque loss you will get to say you have a big cam though and that is what is important right?

Work with one of the shops I mentioned and I bet you end up at least that duration but MUCH tighter LSA and with much better results, it won't idle as well though.

the reason for aftermarket injection is the tune ablitly is right at home on the lap top and 100 rpm changes not 250-400 plus the loss of mass air.we gained at least 50hp with FJO and not to mention there system has wide band and a self learn. the 113 lsa is cause i intend to run nitrous.

i hope you have forged internals

And I hope your engine does, also.

Here's a link to a stock heads (but with all the other correct mods) with a cam and valvetrain system that made good power to 6500 where the owner wisely limited himself. There was a lot of money in the valvetrain parts to get it to run like this. I don't think it would go to 7000, however.

This engine finally pooped the bed from all that hard 6000-6500 roadcourse running. The new engine will have heads, etc and a lot more power.

FWIW: Why stock heads? They are limiting you big time.

just wanted to keep the stock heads for now to keep costs down and spray the motor to make the power i need,the only reason i am looking at reving up to 7000 is if i'm at 6500 3/4 way down the track and the rev limiter goes off.

Change your overall gearing. 500 rpm is only about 8-9 mph in the 110-120 range. If you spray and the car can go faster, you'll have more problems.

Remember tires are "gears" too.

(7000/6500 x 25in.) =~ 27 in.
