I have had my car running for a few weeks now. To me it feels great, to my friends the car feels crazy. Mid range feels the same as it always has, past 5000 the car pulls like a train. Even though I made a few changes to the motor, the basic setup is the exact same. At the same boost pre-build the car did not pull this well.

Caution Huge pic.
 

What throttle body is that?

LS1
The plate is 75mm, the whole thing is 4 inches.

THREADSURRECT!

Have you put any more thought into building and selling these? I would be very interested.

I don't know where you have been but Ive been selling them off of my web site since this thread started.

Anyone else have 1 of these on a running car yet?

Interested in purchasing one of these.

I will be building one for jtothawhat's 600whp build, just waiting for the funds to start.

Hey jim, haven't seen u on the msm forum forever. Car looks good, interesting oil control routing but at least the stock shit is gone

Just thought I would say that FRT_FUN has one of my manis for sale right now, he is parting his whole set up out, and has a good deal on it right now if any one is looking for one with all the bells and whistles. so bump for a good buyer

Hey man aluminum aint that hard just heat it up a bit before you go at it and make sure you clean it like crazy with proper aluminum cleaner and then rub it down with a scotch bright cloth.

Is the throttle body bigger than the diameter of the intake plenum itself, or are these pics just deceiving?

So the one for 300$ is less than a Honda hybrid setup.

How would it compare?

the plate in the TB is about 75mm, the coupler on it however is 4inches/98mm.

No the throttle body is never bigger than the plenum, it just looks that way. The tapering mani starts at the same size as the throttle body opening and then gets larger. The round style is larger altogether but also uses a hemisphere to help the transition so there are no sharp corners.

I can optimize the plenum size and runner length as you please, with the Honda one you get what you get.

What can you do for midrange gains?

Any kind of ideas what actual improvement that would work out to?

From what people have dynoed the honda types, it seems that it helped the mid rang. you could expect more gains from a mani with velocity stacks, in fact I have not even sold 1 with out the velocity stacks. I honestly dont think there would be much difference in gains between my $300 model and the honda mani exept that I can change where it is most efficient. Thats why I offer to do the honda ones as well, its no problem for me to weld them up, and it seems like the good choice for marginal gains at a fairly low cost. Of course if you are going for big power, or want something that is specific to your set up you need something else, thats where my higher end stuff comes into play.
