Was just wondering if anybody has tried out the 90mm TB? I have been looking at this thing for a while but not sure if its worth the $500 bucks just for an extra 10whp. So far i have an AEM brute force CAI, TB spacer, bully dog prog, edelbrock shorty headers (which i freakin love), and completely new 3.5" exhaust piping dumping just behind the cab. This is a 06 single cab with the hemi and 3.92"s. If you guys can think of a better mod for 500 bucks im open to any suggestion except for the cam. Im saving that for the stroker kit.

Here is a link to my ride. I didnt feel like posting them all. http://www.cardomain.com/ride/2503439

 

Thats ALOT of money for a small gain

 

i did a study a couple years ago (2006) and based on HP claims made by the factory dyno's and cost, it seemed to average between $35-$37 per whp. Now like i said that was in 2006. I did it for a high school project and got a B. Teacher was an a$$. So since inflation and all has gone up i figured tuning is gonna go up too...

 

I wouldn't go anything over 85mm on a stock engine, 90mm would be great if you had a huge cam to make up for it.

Check out http://www.thefastman.com/ I have one of his on mine, 85mm, and there is a definite gain right off the start. $237 was the cost of mine with a $100 rebate if you send your stocker back to him.

 

get rid of the throttle body spacer. ive heard real good things about the ported TB's but there expensive. Do they offer it any cheaper if u send your old one in?

 

No. No rebates on this site for the old TB. Here is one of many sites i found it

I think 84-85mm is max for a stock TB body.
$300 or abouts

 

Go to www.thefastman.com His are $237 w/ a $100 core charge. If you send in your stock TB its $137.

ANYTHING over $250 is TO MUCH $$$.

Also with a 90mm TB with a stock engine (no cam / heads) there really is no point of doing this, the 85mm is MAX you should need to go.

 

Great price, short list item...

 

Throttle Body spacer does no good unfortunately.....
