+1. About the same as running a 4" fmic for a stock turbo...

 

damn u guys are lighting up my stock turbo manifold thread...haha...glad there is some good info being thrown in here....There have def. been some new manifolds put out since I started this thread....

 

Loved the full-race manifold I got off Geoff.. Made good power thruout the powerband over the stockie that was rotting out already.

^^^truth. there is no point, and all it does is add lag/hurt response.

 

haha...I ran the BR Race intercooler on my stock turbo setup for a year or so...I knew I would be upgrading turbos down the road so I figured might as well buy one intercooler that will take anything I throw at it....

 

You probably lost some power up top didn't you? If you were pushing the turbo to it's limits anything above 24-25 psi would push the turbo out of it's efficiency.

 

Ran 25psi on straight 93 for a couple years...no power lose up top especially after I get rid of my Forge MBC & put in a Hallman Pro RX...

 

Thats fine. Just put it out for comment.

Is there much gain over a ported stocker? At the moment I have a MAPerformance Ported Stocker, but Im looking for more.. (besides, aftermarket manifolds are sexy)

 

Depends on the design of the FMIC and what you're running. I was on stock turbo and I had to go either 3.75 garrett or 4 inch. I was getting heat soak on repeat runs (and this was before the summer)

 

I was running 28.5 to 29 PSI on the stock turbo until I swapped it out and went BBK full.

 

29? the heck. that's like a 1974 stock beetle going up a hill in sandiego. under 100 percent stress. but i guess that's why they have the story "The little engine that could"

nice

 

a tubular manifold will make more power then a ported stocker but power is up top. most people for some strange reason want to keep it down low hence just porting the stocker. typical gains are 15-25 whp gain. you just have to decide is that plus 25whp worth 750-1200 dollars??? i loved the full race manifold and was ready to pull the trigger then i got the chance to create something new SO i jumped on it hence "Mona Lisa" yes there has been a test posted check out 4w thread for it. If possible and JMS has ported stocker im try and do my own test but we shall see

lifetime warranty as well
"Mona Lisa"



Coated "Mona Lisa"

 

my vote would be full race = lifetime gaurantee



Geoff- would you consider making a oem looking heatshield for the california folks?

I wonder what oem / salvage yards have a heatshield that would cover most of the mani up???

I know it's terrible to cover that up from the wow factor, but it may prevent getting grief from the man

Do you have a dyno compare by any chance?

 

yea go back and edit orginal post and add "Mona Lisa" LOL haa

 

It's not strange that people want low-end power...rather I should say torque, because that is what you feel when you stomp on the gas and it makes the car a lot more fun to drive. If you're trying to win races then you'll probably want to tune for WOT performance, but I'm gonna go out on a limb and figure most of these guys are just driving on the street and that is where you want to hang onto low and mid range power.

Also I don't think you can buy a manifold alone - with no other mods - and expect much of a difference. Suppose you replace the stock manifold with a tubular part, and let's say you have a decent exhaust and downpipe but leave everything else alone...would you still see 15-25 whp gains across the board and how would the new manifold affect the torque curve - because if it compresses the torque curve the car is going to feel "sluggish" from a stop.
