ok, after i put on my performer manifold, i kinda lost low end torque but gained ALOT of mid and upper rpm torque.....is that normal??? the lil adapter plate was 1 inch thick so, ..maybe the higher rise kills low end torque?? correc tme if im wrong

 

That sounds normal to me. How hard was the install? Got any pics?

 

The higher volume runners should kill low-end torque which is what you probably feel. Also make sure all the vaccum lines are plugged in.

 

dont ya love killing low end torque

and this is before the 1" open spacer...

ok first off, the install was a PITA,period. id rather swap 2 cams, than have to install an 86 manifold on a 87+ heads. WAY too much crap was rigged, re ran, bored out, and broken...but , i had the manifold from my previous engine that completly died so, i had to put it to use.....looks great though....run alot better as well....i need some pics of that and the stripes i put on 2 days ago. but yeah, the install was way harder thani assumed it would be, and this is sad considering i swapped a cam and installed headers ona factory car.

 

What did you do about the kickdown cable?

 

what about it?? i had no clearance issues with anything, even with the 1 inch thick adapter plate and higher manifold...are you thinking about doing this install?? if so i can help alot with vacuum hose re routing and all that crap.....let me know, glad to pass on what i know...

 

what was so hard about elongating 4 holes with a drill?

 

heh, you have no clue how little bit of metal you have to work with after you do that, ..i was drilling those holes out and seeing if the manifold would fit on right for an entire |DAY heh...actually one bolt hole in the manifold BROKE an d i had to use a huge *** washer to get it to hold the manifold down. then came the fun of re routing vacuum lines, finding a place for the brake booster. seriously, for some reason this was plain and simple HARD to do. i dont know why. prolly cause every single element about the install was afro engineered

 

What would the effect be of putting an RPM Air Gap manifold on a stock motor that will later on be heated up with a hot cam and heads? I love my low end torque but I want more power too, advice? Thanks.

 

Wait and put the manifold on when you do the heads.The hotter the cam the more low end torque you will lose. And ad headers first before you do anything more to your motor.

 

Well, considering I have done it before, and I had zero problems.

 

damn, no need to get testy, everyone projects turn out differently...heh....mine just didnt go oh so smoothly for some reason, and i had about ZERO metal left to bore out until the holes looked like a C instead of an O .....lets leave the aggression behind next time

 

"heh, you have no clue"

Then don't assume I haven't done something. No need to start whining dude. I know projects turn out sh!tty sometimes. Thats why a simple intake manifold swap has taken me 2 days one time and < 2 hours the next...

 

So obviously you're the only one that's ever done that before?

It's not that hard man, but 1 hour jobs can turn out to be a 5 hour one.

 

I think it's more a case of it being a hard project for him, in his particular case.

 

i think you guys are a holes, i've done all sorts of manifolds and ive never had to rig so much stuff in my life(i just put the holley tbi) and let me tell you gycfjyckgcjycdttyhg is all i have to say about that. but as you guys say the next time i do it it wii only take 30 min. but that would be because all the bull**** has allready been delt with. so no need to get hostile or snooty

 

lol this is funny, im not sure anyone has a clue wtf im talking about but thats ok, ....who just said there was no rigging involved in putting a 86 performer non egr manifold on a 87+ heads?? heh, no riging my ***.....and i think its funny when i make a general statement dealng with MY case , and people think im talking to them directly. learn to observe more clearly

hah if you think installing a manifold is tough wait till you start with some real mods and yes im being an A-hole.

the loss of low end torque may not be so pronounced with chip tuning. The low end timing settings on the chip are pretty weak and just about every car that gets any mods worth mentioning need revision in that area especially.

 

the only thing that could be harder than that sh== is switching to tpi
