Exhaust,intake,throttle body spacer
I have looked at a lot of high dollar bolton stuff online. In the process of deciding and not having picked out a muff, I just took off the stock one, used part of a 180 mandral formed piece and poof. Straight back turn down about the same heighth as it was on the other side protected by the spring shackle.
Idles with just a little Hum, not loud in cabin at 65, a little Hum at 65 pulling boat, (it is a Hummer) but stomp it and it talks! Seat of pants dyno says, oh yeah, if a Magna flow is low resistance go figure no muff resistance. Figure HP gains with any muff and then no muff. Dyno results in about a week. Kept Cat and res which must be like an old Cherry Bomb glass pack to be this quite with no muff.
Im working "with" a local manufacturer of throttle bodies and air intakes. I just happened to be the first H3 to drop by. Tuesday we are going to try a Colorado throttle body and make any mods on the CNC. Then fab up an air intake. Dyno for results of HP, torque and then do some MPG. Results on a Colorado were 10HP and 6 FTLBS 1 to two MPG. We will see. Pics to follow also.
I tried to be brief! Now if I could put a fuel cell in that hole for more range........

Re: Exhaust,intake,throttle body spacer
Its great seeing people out there getting their hands dirty! I had my muffler and resinator cut off. Had a flowmaster 40-series with two turn downs welded in where the resinator use to be. I love the sound and performance of it. I plan on putting a Y-pipe right before the muffler so I can have an open exhaust for wheelin when I need it. I love trying new things and give props to the people that do too!! Keep up the good work and keep us posted on the progress!!

Re: Exhaust,intake,throttle body spacer
I got the true flow air intake installed today. I will drive with the open exhaust and this intake until Tuesday. Im supposed to get on the dyno then and compare the other mods.

Re: Exhaust,intake,throttle body spacer
oops dropped the photo! Im still grinnin from the exhaust so its hard to describe the intake. Seat of pants dyno feels more responsive throttle and more acceleration. Im noticing a little lower rpms at 65 mph. Hmmmmm

Re: Exhaust,intake,throttle body spacer
question, how did the throttle body spacer do? Have you thought about a commputer tune yet? I have also felt the same from my true flow.
