I was thinking of going for the street version of the JM fab manifold. I can't find any numbers on the street version. I talked to Jim at JM and he advised the drag version at first but when considering the type of mid power I want and the all around car that I expect mine to be we settled on the street version. I just wanted to see if there are any numbers out there. If not come this spring I will have some. I also don't want to wish I had gotten the drag version either. Any imput is welcome.. Here are my mods. I drag and autocross (I just like to race!) if anyone was wondering..

JMF told me the street version would be a worth while upgrade on a evoIII powered car...

I would go with the streer version, everyone is on the big donkey dick bandwagon nowa days...

Match you setup, you said you like to drag and auto cross? So having a fat power ban is key to a daul purpose car

But anyways, how do you like the BB 50?


Your setup looks to be properly tuned, so your imput would be reliable...
 
Love the bb 50trim. It puts me right where I want to be. Talked to Jim again and ordered the street version. I agree a matched setup is more important then a super big 4 inch stainless donkey...You get the point. I'll show some numbers this spring when I get back on the dyno.
 
24 lbs. of boost on pump. I had to turn it to 22-23 on the street due to some knock. So I am probally 8-16 awhp less then my dyno readout. I am going for a better tune when I get rid of this stupid boost controller. Also going to try not to dyno on a 95 degree day! It hits 18LBS. hard then creeps to my setting. I think the passage is to small to let enough air through to slam the external gate open. Also adding a JMF street mani (ordered).
11.50's here I come...

Are those your current or new dyno numbers in your sig? You should do a dyno graph comparison of each set if you can..

To show others how much HP the street manifold gave you, and also dyno at the same PSI ish..

Thats if you can, it would help out others when looking to select parts etc
 
Numbers are current. So I will do that. I am adding a aluminum driveshaft and the JMF manifold. Driveshaft will only make the curve a tad different. To be different I am getting the mani powder coated black..Thought you may like that no bling factor. Boost will be a tad less. I am switching to a Tial and running the 23.20lb spring (2 springs actually).
 
Nope just a 1G intake manifold. Ohh I have an Evo Filter and adapter plate going to the 2G MAS...That's all. I can't give up some logs untill I get my power plug back from a friends house.
