hello everyone I been looking at this blox 74mm tb, and I was wondering if anyone has any problems with it or good results thanks........

 

..your prob. better off with RPM sevices or BDL 74mm throttle body.

 

thats huge....

do you know who sells rpm tb's at a decent price ?

 

what kind of power you plan on flowing through there

...Snail EG on here was i think. but yur better off with BDL TB. contact Laskeyracing

 

bdl thay will not stick.

 

Does anyone have Clonclusive proof that Bigger TB's work for Turbo Applications?

why whould one wanna put on a 70/74mm TB. on a F/I Car? all the Info i have read on the Bigger TB for F/I is only go once size bigger to defeat the restriction cause buy the butterfully its self...

Or how does it work?

sorry to state the obvious here...but it helps, because it's more volume. Think of it as a water hose. a 2" hose at 35psi will only flow so much. But a 4" hose at 35psi will flow FAR more. That is what the OP is looking for, to put more air in.

 

we ran a few blox throttle bodies on our customer cars with no problem.

we test a lot of products before we sell them to confirm its a good product.

the price on these things are damn competitive compared to rpm service etcc

PM us if interested

Yeah i agree with you on that but so many Sites say it makes no Differene!!!

Im sure they are very gewd, they look the business. Just wish there was a chart were sumone could show the Positive Effects(Improvemnet in Performance) of a bigger TB(60,65,70,75) so i can finally prove all these other idiots wrong.

 

The box one looks identical to the RPM service. I own an RPM service 70mm on a Edelbrock IM on my turbo B16, still in pieces so i cant vouch for the performance yet, but larger diameter = more flow, so it has to be better

 

then why not put a 100mm on there?

bigger in this case does not mean better

troof!

 

Isn't the idea just to establish a smooth transition into the manifold(i.e. eliminate bottleneck)? If you have a 2.75 inch charge pipe, then you want a 2.75inch(~70mm) throttle body. Anything smaller and airflow will be slightly restricted. Smooth transitions ftw.

 

It all depends on what the power goals are.

It's like using an SC61 for 300whp, you can use it but it's not optimum....bigger is not always better everyone knows this.

 

The smaller the throttlebody, the better the throttle response (within reason). The larger the throttlebody, the poorer the throttle response, but the ability to flow a larger volume of air (within reason).

^^INTERNET MYTH #147: In my experience this goes out the window with forced induction. Read below...

PERSNONAL EXPERIENCE, not internet heresay&gt;&gt; I've used and tuned quite a bit of setups with aftermarket tb's and have made great power with them with no drivability issues at all! If you can get them to not stick, big bore throttlebodies are excellent for boost.

I happen to have a spare 74mm blox tb I'm going to throw on a 84x89 VTEC Build along with an edelbrock mani. I'll post the dyno printout soon...

 

Once the TB is wide open, its essentially just a tube with a bar across it. To put it bluntly, the TB is rarely a restriction on a Honda. A larger TB may help, but if you knew anything about carbs or physics, the Venturi Effect allows air to compress further and travel faster as it encounters a restriction in a tube. Not much energy is used to force the air through the TB. Futhermore, each runner is like 1/6th the cross section (area) of the TB, and only have 1 runner injesting air at full speed at any given point. You are far more limited by the intake runners/cam lift than the TB.

There is a point where you will flow more air than the TB can really deal with, but thats at 500+ whp for a Honda TB. Consider how a t04e cover usually has a 2" ID outlet in most cases, but still supports over 500whp. And given that the outlet temp is ~100-150F higher than when it passes through the TB (uses more volume when hot)...

Know fact: Dyno just a cam that [overall] gives 20% more flow (lift/duration/etc) vs just a TB that offers a 20% larger cross section. On most Hondas, you'll gain far less by adding a TB than by adding an intake cam.

 

I agree, that Blox unit looks just like the RPM tb. BDL does make a few other company's stuff, but the blox is not made by them. BDL has a pretty good warranty if bought through a reputable dealer. So if there is issues with their tb's...they get taken care of which is nice for a company. Keep in mind the BDL unit is tapered from 74mm at the opening to 72mm at the butterfly.

 

i just got my blox 74mm today. looks good and its def. going in my new build. fits a 3" hose and charge pipe perfectly.

lol

 

FYI the rpm service 70mm is larger diameter than the edelbrock victorX #4764 inlet. I had to take the setup to a machine shop to port match the mani to the tb.

 

a bigger throttle body with out porting the tb flange wont accomplish ****....
i personally run a 90mm tb.. but its a on a huge built motor.
