Hey,

I just installed my Direct Flow lid from ls1 motorsports. I noticed a big gain! I also went ahead and did the free ram air thing also at the same time.

Does anyone know how much HP that got me?

Thanks,
Shawn

 

I've heard 10 to 25. I just put a SLP lid on with no ram air and could feel a little more response in the low end. I havent had it to the track or dyno so its a seat of the pants deal.

 

Since most lids are the same...I got (I think) 14rwhp and about 10rwtq with my MTI lid. This was over a factory lid and filter...the car was stock except for !FRA and Diablosport tuning.

 

I dynoed my MTI lid.. info is in my sig.. Click on the review part..

 

Here's what I gained. I did about 14 pulls on the dyno. I would change something then do a pull.

SLP lid and K&N filter 11RWHP
Supersucker ram air 13RWHP
Gutted cats 6RWHP

30RWHP on just a few simple mods. One free

 

i gained about 10
