Help! Will my current cam work with a supercharger?
Help! Will my current cam work with a supercharger? Thinking of buying a v9 g trim supercharger for my 02 Camaro. I'm just wondering if my cam would work with it or not. The cam I have is the Asa GM cam I believe the specs are 226/236 525.525. 110 lsa . With supporting mods Slp lid, bbk tb,ls6 intake,pacesetter lt's, Slp exhaust. Any input would be greatly appreciated .
Will it work? Yes. Is there much better cam specs? Yes. Believe it or not, the stock cam is decent for a fi motor. In your application I'd go with an LS9 cam. Plus they can be had for decently cheap.
It will actually work real good. Don't know why people think wide LSa is best for blowers. Our shop runs alot of tighter LSA Cams in our blower projects. Makes real good power.
Not what I would run with that small of a blower. Try poking a bunch of holes in a straw that you're currently drinking a soda out of... this is what excessive overlap does to blower engine... all the pressure goes out the holes you just poked a.k.a. overlap. That said I'm not advocating a 120lsa or anything that wide but if you could have the same duration you have now with a 114lsa that is about what I would consider ideal for a 346 with that size blower. Just widening the lsa 4 degrees knocks 8 degrees of overlap from the profile which IMO in this situation is needed.
That is the old ASA cam and uses pretty old lobe technology, much better stuff out there now IMO.

The reason I'm asking is because I do not want to swap cams out and all that. But if I have to I will. I'm currently at 390rwhp. With all the smog stuff and cats on it. My question is will I atleast hit the 500 mark without smog stuff and a v9 g trim setup? Or should I just forget about a blower. I have the chance to get one for really cheap and don't want to lose out on this deal

Verdad Gallardo Oh you will definitely make those numbers no doubt, and it will make pretty good power on a low boost setting, from what I've seen though the added overlap on the smaller blower and engine will effectively make the blower seem smaller than it really is. Centrifugal's work off efficiency, and if you don't make the engine that the blower is bolted to as efficient as possible then you've just lost power you could of made. It should for sure make your goal, possibly on 7-8psi of boost, maybe 9-10 if you want to be sure depending on your dyno.
Ok. Well it looks like ill be getting this setup. Hopefully ill hit over 500hp. also what size injectors would u recommend? thats the only thing it will be missing in this kit. and what makes the whistle on the superchargers? I want it loud
That cam should be fine,there are alot of blower cars running way bigger cams than that,just the other day i saw a vid of a gto with a trex n procharger run 10s,a local i know has a vette with a ms4 /procharger and his car runs very well

Spoke to our local yella terra where i am a few months back when i was comingto the end of building my motor and they said they have run there blowers on camed n/a only setup cars and had great sucess, whether that was just a sales pitch or not but have seen some figures here from there's and backs up what they've said.
Was there larger 2.9ltr blowers so may also be why.

Ok so 60lbs it us. And bobs99ss yes I think I should make some decent power. And I think I did see that gto with trex cam and blower. Was it a yellow one u seen? Also thanks for the input guys. I'm just gonna go for it ill post up on here how it goes and what my end results are. Thanks for all your inputs.
Yea. I will just run it and see how it does. If not then I will switch for a better cam setup for blower. Also what's a good secondary fuel pump brand? And what's the usual price for it.
I did dual in tank walbro 255's. They are cheap, reliable and a good pump. A lot of people do the boost a pumps, but I don't have any experiences with them.
