I just read an ad for something called a throttle body bypass. They claim by rerouting the coolant around the TB that you will gain 6-8 hp at the wheels. I was wondering if anyone here had any knowledge on the subject. Is this same? are the gains true? Has anyone here done it to their z33?

Common practice on a lot of cars.... 6-8hp.... nope. As air rushes by the TB, it creates a vortex... it super cools the air & creates frost on the TB. If a lot of frost builds up, it could cause the TB to stick (open or closed). Thus, car makers run coolant through the TB to keep it warm. It really doesn't make much of a difference when it comes to hp.

Where did you read that from? I've never heard anything remotely close to that. I'm not buying it even a little. I can't honestly tell you why the coolant lines are routed that way, but I can't believe Nismopick's story. Creating frost in the throttle body on an engine that runs at approximately 200 - 220 degrees; even if the ambient air temperature is at the freezing point has to defy some law of physics. If the throttle bodies really do make a vortex that super cools the air to the frost point, then why would anyone want to buy a cold air intake?

i know it happens in carbs, like in the C-152's even in 70 degree ambient tempuratures its the acceleration of air speed and the pressence of moisture in the air that builds up ice.... now weather this can happen early enough on to effect a TB idk.... but either way it was made that way for soem reason, and i dont think you can get any HP from it and if so none worth while to change the manufacturers functionality setup.

Do some research brah.

There's about 4.2 trillion webpages that come up when I search for "throttle body coolant bypass." It's been talked about & done for years. It's been proven to be a minimal help... 1-2hp max on a wonderful day.

acura-legend.com..... OF COURSE!!!!!! duh why didnt i think of that.

this whole topic is somewhat.... rice ish... and petty. lol. i think it should end, there's some answere's, now we can leave it and hope it never returns

I routed the water off of the throttle body on my car and saw gains of +3 ricer at the wheels. No frost though.

NismoPick

ah yes... the ricer scale.

1 ricer = 3 vin diesel

1 vin diesel = 2 paul walker

4 paul walker = 1hp


It's science.

Bleach

so that's uhh.... 9 vin diesels.... uhh.... +1 horsepower at the wheels. sweet!

I wasn't debating the insignificance of it's effects. I agree with you on that point. I bypassed the coolant lines on my no TT...no frost yet. I did it merely since it removed some lines I didn't need. It cleaned up the engine compartment a bit. I didn't expect any gains. I'm merely disputiing your claim about it creating a vortex and building up frost in the TB's in normal temeratures, or maybe you were wanting to say that it only applied in cold weather. The coolant lines around the TB's only seem to serve a purpose in extremely cold areas.

1 Ricer = 2.5HP??? Say it aint so.

you actually did the math?!

good job, congrats.

If i had a z33 that was turbo rigged and paid for all that fancy inter cooling I don't know why I would want to just reheat the air again? Rice? i guess you could steam it with the heat...

Makes me think of all the kids at the local track putting dry ice on there TBs

lol, 1st post and he did what entropy is gettin pissed about. but at least its not a stupid old thread. just a few months

Every little bit helps.....when I see companies like Calloway and Hennessey do it, then it probably makes a difference. Now, if it's being done on a Civic, then yea.......that's rice.

trashguy

The ricers do it for the steam effect ^^ it looks nice through all that purple neon

Oh,....yea,....that's rice. No doubt.
