So I was doing some research on intake manifold mods and came across something the guys at GS put up. Has anyone done this mod? Any noticeable gains?

Tweek's Turbos · 04-30-2008, 04:51 PM

About 20 foot pounds of torque, but no numbers on air/fuel.

Moonracer · 04-30-2008, 04:54 PM

Nick said it helps alot in the midrange rpm but hurts on the top end. I'm thinking about doing it to mine. I like more midrange as I do't run too high in the rpm anyway

brewtide · 04-30-2008, 04:55 PM

I ran it, for a while....

Look for some of my posts?

No afr's, never got to the dyno, and the turbo manifold is back on...

PS. More than 20ft/lb I'd have to say, more like 20% gains...

GS has numbers on here somewhere. Search for Genuine SAAB or Nick

Corn Cob · 04-30-2008, 05:22 PM

Yeah I have one in the garage I want to put on but the A/F ratio thing scares me. I asked nick about it and he said it is bad without a custom tune. He wouldn't say if it runs lean or not though. Jak thinks it may be alright but a dyno session is strongly advised. So I really don't know how safe it is, I would guess that on a mild setup like mine the trionic could compensate but I am not fully sure. Since brewtide is a slacker and never went to the dyno one of us needs to just go so we can get this cleared up. P.S. just kidding brewtide don't hate me you have been very helpful.

jonny72888 · 04-30-2008, 05:58 PM

why would you need a tune just for switching out the intake mani? there is just going to be more air there.

TheTalladegaKid · 04-30-2008, 07:20 PM

haha ok so does anyone have the manifold installed and maybe running a wideband gauge? If so... what are your A/F readings?

I cant imagine it doing anything but putting the motor into limp mode... For the most part I'm sure running the manifold wont be an issue.

Corn Cob · 04-30-2008, 07:41 PM

Are you running an MBC? I am so this means if things go wonky the ECU can't pull boost which of coarse is very bad. You could remain safe by raising fuel pressure but that is not ideal because you would be increasing fuel through the whole RPM band and not when it is nessisary. The thing that sucks is that if you don't live near a tuner then it makes it hard to do a custom tune. Jak says he can right a tune for it so maybe talking to him is best.

the link for anyone who is interested, it seemed to work well for nick's car, but i wonder if it would make things worse for lightly modded car

Thats funny. I thought those pics looked familiar.

It is an easy swap. It will mess up fueling a little but should not be horrible.

The is not possible for the viggen/ T7 because of why again?

Tweek's Turbos · 05-01-2008, 09:04 AM

T7 has a funky angle on the tb and manifold, it will bolt to the head, but the tb may interfere with the strutbar or firewall if i 'member correctly.

Yeah, it does seem like an easy swap. Does the viggen exhaust manifold match up as well?? I saw a post on adding a 9k exhaust manifold to the NG 2.0... right now im running stage 4 SQR with a TDO4HL-15t... so bolting on the turbo obviously wouldn' be an issue. Does the viggen manifold have a higher flow of exhaust?? sorry im completely off topic... haha.

The thing I love about SAAB's are that you can use parts from other SAAB's as performance parts..haha.

Thats what happens when you use almost the same engine in all your car models for several years. Got to have mechanical variation somehow.

how will it run at the top end too lean?

and what about the N/A manifold allows a lot of mid range power and reduced top end power?
