Do you have to use a 58mm TB on the Super Ram, or can I use my 52mm BBK on the super ram??

 

52mm will work fine , i'm using a 52mm on my SR

 

52mm will outflow the motor until you are upwards of 400 cubes, a 58mm on a 350 will slow down air velocity and hurt low and midrange power, ie bad street manners.

 

You can run whatever TB you want actually. Before I got the proper mounting bolts for my TPIS 58mm TB I was still running the stock TB on my SuperRam. I wouldn't buy in to the "58mm is too much for under 400CI" hype because nobody here has actually compared them on a highly modded motor.

 

I'm getting the 219/219 cam and I have AFR 180's on the way. I just wanted to make sure my TB would bolt up no problem. I read a post somewhere that said you NEEDED a 58mm TB. Thank's for clearing that up for me everyone.

 

Sure, pal. Can you back this up with some proof? Until then, this is nothing but a modern FI myth.

 

sure i can back it up. call tpis like i did and ask them. they will say the same thing that i just did. they told me, "If you dont plan on building a 406, a 52mm is plenty. A 58mm on a 350 is overkill. You will lose bottom end." Those are exact words from people who have worn out more tuned ports than i will ever see. And companies like to sell things, so why didnt they bs me into buying a $200 dollar extra throttle body. because its not necessary.

 

Information that TPIS gave you over the phone is not 'proof' of anything.
Nobody on here has done the testing to 'prove' their point so now it is just a disagreement

 

Such hostility, but there is good news. I just saved a bunch of money on my car insurance by switching to Geico.

 

Sorry for coming off like a jerk. I just know how my friends' cars run with 350's and 58mm tb's. They ALL say they like the throttle response over stock and they all run 12's. I don't think a 52mm tb is bad at all for most motors, but with decent sized cam and heads a 58 will never hurt, even a 350. Of course someone could argue this forever, because people think differently about what a big cam is and so on. 91wtRoh, should obviously reuse his 52mm tb to save money. It's the people who have stock tb's that I'm trying to let know that if you have a wild setup a 58mm will not hurt. I've posted this in another thread, but some people just don't see what I'm getting at. They can't understand my point. A 58mm tb does not hurt power or throttle response except if you're running stock intake components or head or cam, then it will hurt. Peace.

thats cool man. i just posted because i wanted to let people know that if they want to save a few bucks, a 58mm may not be necessary unless youre making big power. i dont think a 58mm would hurt much either. nobody races at part throttle, so that lost bottom end is only going to show up during street driving if at all. If you got a car that already runs 12s, then the loss is probably negligable. if you got the money and plan on building a monster, then a 58mm couldnt hurt.

 

Yes, I agree with Camaro Joe. If I had a stock TB I would go with a 58mm, I feel that I would have enough airflow in the 355 to only benifit from it!!
