Yeah I know this has been discussed numerous times, but why can't I find anything when I search?? I just bought a newly rebuilt head and being that I have 4 NA cams laying around I thought why not just do it. Is there any conclusive evidence that it improves performance? Any info would be greatly appreciated.

Thanks

Mo

yeah..with the na cam i think its the intake it gives u 10hp dynoed at the rear if memory corrects me

 

[conundrum07]

I cant find the thread, but Dr J dynoed it IIRC. Something like 12HP and 17TRQ.

 

[Mo87NA]

Hey Doc can you give me some information on this. Feel free to chime in any time

 

[Mo87NA]

Is anyone using this setup??

 

[suprachung]

im gonna do it...i dont see why not

 

[Silver88Turbo]

It wasnt the doc that did it IIRC. Im surprised you didnt find anything when you searched....

 

[makenzie71]

ummm...search doods... "NA Cams"... lots of hits...proven fact...in pre-89 cars NA cams are beneficial.

 

[Mo87NA]

Yeah I tried. Maybe I just messed up or something. It wasn't the Doc who did this, you were right. I just spoke to him and he said that it lowers the power band and hurts top end, but it improves low end.

yes and no......i think the bottom line ended up being they are beneficial TO A POINT.....a good early mod but anything past about 300-350hp and you are better off having the turbo exhaust cam in....

which by the way the only one different is the exhaust one...you dont need to change the other one... FYI

dr jonez never did a dyno test comparing different cams.

 

[Mo87NA]

Thats awesome man. Thank you!

I have the NA cams in my truck. I don't really know how much of an improvement they made because I changed lots of other things at the same time.

*Turbo: 4 wastegate washers (now 6 (done after cam swap)...
is this when he dynoed it?

 

[Silver88Turbo]

I just spoke to him and he said that it lowers the power band and hurts top end, but it improves low end.

I could have sworn it moved the power band UP slightly less than 500rpm, sacrificing some low end torque for more horsepower. I could be wrong though. If I could only find that old link.....

nope, wasn't me.

ideal hit it on the head.

My friend Ti (Poi Dog) did the NA cam conversion on his 88T, and said he didn't like it and really didn't notice any power gains from driving it, so he put his GT cams back in. Just my .02

 

[Freedy89T]

I just spoke to him and he said that it lowers the power band and hurts top end, but it improves low end.

It looked in that dyno like the NA cams had less low end power before spool, and then had more(but got consistently less) towards redline. What is it about the cams that make them help on lower Hp cars but hurt on higher horsepower cars? That doesnt make much sense to me.

BWTF THAT GUY WHO DYNOD the car didnt installed 550 with lxs afm !!!!!!!
