I remember the big long thread back on TSN debating whether or not to replace the exhaust cam with another intake cam. I was wondering if anyone ever got around to running a Dyno with and without it. Also it got me wondering why saturn didn't just have two identical cams on all the DOHC motors and save the money it would cost having two different grinds, especially if there is a minor gain using the two intake cams.

because saturn doesnt care about performance gains, they are worried about reliability, emissions, etc... -
Aint that the truth. The intake resonator looked like it didnt even belong there lol.Originally posted by Ralliart16
Intake cam for exhaust cam? Higher lift?Comment

higher lift and longer duration. IIRC you set it 180* opposite and then retard one tooth. I'd assume saturn and GM would be cheap about it before they would consider performance at all, meaning one grind for all cams-Mike-MN <br />'96 SC2 <br />Check out my website!<br />[img width=350 height=40]http://www.sixthsphere.com/storage/976/stc_banners-oakdog8.jpg[/img]Comment

has whoever that did already noticed any mileage changes. obviously it'll give better performance after a tune but will it affect gas mileage negetively?Comment

what does mileage matter if your lookin for power, you have to sacrifice one for another (maybe not much of a loss but maybe a noticeable)Originally posted by andy_wh2000[color=red]-Tyler[/color]<br /><br />2005 Chevy Trailblazer<br />1999 Saturn SL2<br />2002 Suzuki Bandit 1200Comment

natedogg from TSN Buttdyno'd it and said that he noticed minor gians up top, a smoother idle, and said it didn't seem to affect gas mileage much. I'm just wondering if anyone has since gotten their car on a dyno with them-Mike-MN <br />'96 SC2 <br />Check out my website!<br />[img width=350 height=40]http://www.sixthsphere.com/storage/976/stc_banners-oakdog8.jpg[/img]Comment

hhhhmmmm, how well would this perform once you add F/I?sigpicComment

thats what I was wondering. maybe I'll try it. [img]{SMILIES_PATH}/icon_twisted.gif[/img] I've already got the MS to tune it. I could go to the junkyard and pull a cam in like 30min I bet, since I wouldnt be concerned w/ the timing. I just don't want to hurt my baby.Comment

I belive natedogg was turbo'd-Mike-MN <br />'96 SC2 <br />Check out my website!<br />[img width=350 height=40]http://www.sixthsphere.com/storage/976/stc_banners-oakdog8.jpg[/img]Comment

I would be a little worried, I am using the SAFC2 for fuel tuning(no timing [img]{SMILIES_PATH}/cry.gif[/img] ) I may have no choice but to convert to MS once I do go F/I.sigpicComment

I wouldnt waste my money on anything other than an MS. I'm telling you guys, its just not as hard as you think to get a MS setup running. The hard part is earning the money to buy the damn thing. Its also fun to tune it.Comment

I was just trying to get to the point of if it had a performance gain and little to no mileage loss that it is odd why the car wasnt built that way in the first place.Originally posted by sl2fastComment

TOM did this on TSN
he had a 92 DOHC and some how found that the ( 91 ) DOHC head come with the funkey intake cam
why I'm pointing out the 1991 DOHC part is he found that only the 91s had that cam ( as far as I can remember )
but you can do this swap with aney ( intake ) cam to gane the added over lap between the intake and exhoust camComment

TOM was running a AUTO tranery in this car
but yes he did get a nice fealing from the "but-dyno"
and he hinted at the better MPGComment
