How much if anything will i notice from installing 52mm tb on my car? Right now it has a hot cam, mac-mids, and a cai. Would i be better off getting a electric water pump, or 52mm TB?

Before anyone says a TB cost to much for what you get, i'm planning on getting a used for $150ish. I plan on getting both before i send the pcm off to get it tuned in a few weeks. i just want to know witch one i'de be better off getting first.



Also i think i've seen that the openings on the stock intake are 54mm, is that true?




Thx guys

 

My priorities would be to get it tuned first then i'd go E-waterpump as you'll get more gains than a TB. You do need to make sure you get a tune after your TB though because you have an A4 car. I personally wouldn't waste the money on a TB with your mods. After heads it might be a good idea.

 

I seen some place on here that a 52mm tb will get around 7rwhp on a stock lt1. Would a EWP really help more then that?






:edit: just looked at your CD page, and damn i want to have sex with your car. that thing is freakin beautiful.

 

electric waterpump, or a cut out.

 

dont think the t/b comes a restriction, with just a cam, mostly only after heads

 

chalk up another vote for EWP

 

I definitely agree. You should have some more power tied up in a tune if you haven't already done so. Then work you way to the EWP, and finally the TB.

 

Thanks for the compliment my car has under gone a lot of changes since those pics. I now have a 97+ Camaro dash and the new bad *** Hella 90mm head lights. Now that my GF has a new bad *** 5-6 megapixel camera i'll probably take some good quality pics in a nice setting.
www.ws6.com has graphs of gaining 6.5 rwhp with an E-pump. Many others have documented 8-10 rwhp gains with just the pump, and it'll help keep your car a lot cooler. The stock pump flows 25 gals per min at 6000 rpms and the electrics are 37 gals per min all the time. I can't believe gains of 7 rwhp with a 52mm TB unless it was on a big heads and cam car.
