ZZP throttle body turndown?

[industrialfish]

We all know TB spacers are useless for most people, but does the ZZP turndown have any negative effects? Right now my 9" cone is clamped directly to the MAF. I don't plan on ever getting an intercooler, but I like how the turndown looked on Smuts' car and it would put my intake closer to cooler are at the fender wall. I wouldn't bother if it'll reduce the flow too much though.

Your filter probably wouldn't fit then it'll hit the spot where the pcm sits

That's a good point, without the extra height from an intercooler, I may not have clearance for the filter.

Although, now my engine is lifted .75 from Vinnies spacers. Screw it, I think I'll go for it. Can always resell it.

yeah zzp needs to take at least 5* out of the turndown...it bends down too far on the 04+ tb pattern units

go **** yerself pizzaboy

lol my new camaro on the F body forums...do you even drive bro?

[Russosaur]

Ever considered using PVC? I can only think with the added bit for the MAF it might be too long and hit things depending on the bend. Plus depending on the couper you get it can look kinda weird.

Nah, going to try to stay away from PVC on this car... for now. And yeah, adding a bend between the MAF and filter looks odd to me. Sticks out too far then turns and stick out some more. At that point I'd just got full CAI

[Russosaur]

Maybe you can find a peice of pipe bent at like whatever desired angle you need. You know like those chromed up ones you see people have. Probably kinda expensive but looks better than PVC.

The turndown is only 72mm (aprox) ID. so the turn down is a restriction for your throttle body.

[industrialfish]

Hm... I thought L32 WAS 72mm

[Turbocharged400sbc]

its 75mm but its effectively 70 with the way the blade and airshelf is designed to allow for small airflow correction via the stepper motor.

welcome to the compromise of not having a pintle type IAC and a 3$ cable....

[industrialfish]

Yeah I just went and measured it. 76mm on the MAF side, 75mm on the SC side.

Turndown for what?

See the black bend thing between the supercharger and the throttle body?

EDIT: Yes, I completely missed the joke.

[sseilmnop]

The inlet turn down is approx. 70mm.

Turbocharged400sbc Where did the effective 70mm come from? Is that your guess or is that from some where?

[industrialfish]

The inlet turn down is approx. 70mm.

Man... Nowhere on ZZPs site do they say what size it it, but they reference the Gen 5 multiple times which leads me to assume it was the same size. That seems kinda shady.

[sseilmnop]

I measured it before and it is 70mm. No way the stock
TB is effective 70mm. That is almost 15 percent smaller than 75mm.

[Turbocharged400sbc]

the good news is that you can control certain 90 millimeter drive by wire throttle bodies with our TAC
at least then your throttle body is larger than the blower inlet.
