I have a chance to get a good deal on the ARD 57mm...I know that the optimum for our engine is 55mm though...would the extra 2mm hurt or help out that much? Don't suppose there are any DYNO's out there comparing the two...is there? Thanx for voting and helpin' a brotha' out!!!

Poll question: ARD 57mm TB VS. AFX 55mm TB...which would be the best for performance

Poll result (6 votes) ARD 57mm TB (4 votes) Vote AFX 55mm TB (2 votes) Vote (0 votes) Vote (0 votes) Vote (0 votes) Vote (0 votes) Vote

I'd go with the MP 60mm TB...but since you mentioned about a hook-up I'd probably go with the ARD 57mm...I hear some bad things about AFX services...and besides, if you got the MP 60mm TB, whenever you decide to do the P&P Intake mani, obviously you get the biggest gains with more flow.

heh heh ....I didn't vote cuz' mine wouldn't count :7

the ARD is a quality piece, my friend ;-)

I had Howell bore out my TB to 55mm. I was very pleased with the quality of the work and the turn around time. Took approx 1.5 weeks to get it back to my door. Think if your gonna stay NA, then go with Howell and save 40-50 bucks...if forced induction is in your plans, bigger is better!

why would 55mm be optimal? i thought the more air the better?

probably depends on the kinda mods you have to support it.

Bigger is not always better. You need to look at the air flow numbers. Here is a sizing formula. http://www.howellautomotive.com/forum/viewtopic.php?t=222

I have 57mm mm tb from ARD and honestly, it doesn't look that much bigger then the stock tb. 2mm is like the width of a fingernail if even.

Both tbs will bore out that hump the stock tb has which will increase airflow.

Arguing about 2mm is just not worth it.

I will say that if you're planning to do turbo later, go with the larger one. Turbos just react better to mods, so that extra 2mm will make a difference.

thank you all...after carful consideration (about 30 min.) I decided to go with the 57mm...and will hopefully get to pick it up on Sun. after I get out of church!!!

I got it I got it!!! I am just waiting to get out of this stupid class so I can go down and get a new TB gasket, so I can slap this baby on!!! I'm also thinking of sending it somewhere to get it powder coated too (along with a VC), to match my intake...it's just a thought for now. I really just want to put it on a feel the difference!!!

thanks William for driving all the way over here.

now put that thing on plus your exhaust :thumbsup

I used to have the 57MM TB and did the 60MM Jeep TB mod and I love it.

hmm now wouldn't it be better to have a taper though? its there to increase intake velocity. I think that's something you'd want probably wouldn't be as important on a turbo engine though. but yeh like a 60mm tapered hehe. or screw 1 tb just go for itbs :P
