Well the way I was looking at it was cams on a PI car, I can see. But with the design of the NPI cams being so poor, you could see more of a gain with aftermarket cams. Thats what I'm thinking.

I mean when you can swap to another STOCK camshaft and gain 10-15rwhp, if swapping to an aftermarket that would usually gain 20-25rwhp over said stock cams, can you not see where I'm going with this? Does that not make sense to anyone else?

I know for PI cars its only about 20-25rwhp. But when we're talking PI cams being added to NPI cars and picking up power, then people claim 20-25rwhp over the stock PI cams, that adds up to quite a bit more than just 20-25rwhp.

Or am I way off my block here?

Yeah man, if you're so sure about everything than just have your buddy spend the money, do all the work and post up what his car puts down (or even better ET differences). Why even get carried away by numbers on a dyno when you are talking 250rwhp?

Just an FYI, STOCK NON PI HEADS cannot even be compared to STOCK PI HEADS...

Look at it this way, the best my non pi setup has EVER laid down was 370rwhp/380 tq....that was with a blower pushing 14psi, intercooler, PI manifold, STOCK NON PI CAMS, STOCK NON PI HEADS...And just for your numbers sake, I picked up 110rwhp with just putting on the blower, another 40rwhp from the intercooler and pulleying down, so 150rwhp, minus that and you are at 220-230rwhp...

i get your thinking, but you're off with swapping from a stock non pi cam to an aftermarket non pi grind. You wont pick up anywhere near 40rwhp, as mrt and I said about 20-25rwhp and 25rwhp is on the high side.

I understand the logic behind your reasoning Teej, but i just think your number predictions are a bit too ambitious. I'd just hate to see your buddy do all this work, expecting higher numbers, and be let down.

We all work hard for our money, and it sucks when we do something to our rides (something that sounds correct on paper) only to be let down.

Dude, I dont know why you're getting so flamed over here and starting to get all on your high horse. When I asked about your setups, I'm genuinely interested to hear what they were! But looking around, people seem to suggest PI stuff over anything NPI.

I tend to go for the "more with less" mentality so thats why I originally suggested the cam/intake swap over the entire PI swap. Less time and less install to worry about. I was pretty convinced that the gains between the PI swap and PI intake and NPI cams swap would be similar. I wish this was my car and I had the choice because I'd love to try it. Even if it didnt make as much power, I'd bet that it'd still be a damn good race between the two cars!

And thanks for the kind remark MRT. I was talking to my buddy on FB and he is saying his goals are 300rwhp...neither option will get him to that mark! Looks like he'll have to do a blower or turbo to get that power!

Oh no my tbird isnt blown. Thats my Gt with the centri Im going to run a set of stage 1 blower cams from mhs and I was thinking of after taking the cams from my gt to just pass them on to my 96 bird. Nah that tbird isnt blown looking at it my sig may be a lil confusing.

97stanger

Not flaming mad at all, but when you ask for opinions and you are given them, just take them with a grain of salt when your predictions are way off

97stanger

ahhh got ya, that should be a fun ride with the cams done. Ever think about intercooling?

Rockwell28

Most definately I had an aftermarket jdm small intercooler that I picked up when i had it all set up but the installer/tuner couldnt get that intercooler kit to work out so I took a $10 loss from what i paid $179 and sold the kit on craigslist. But it will be getting intercooled no doubt.

97stanger

not bad, atleast you got your money back for it. with cams/intercooler I bet you would just about max your internals out.
