Size of coolant hose for a "custom" bypass? Anyone happen to know a the size hose I need to run from the radiator neck to the front coolant pipe to bypass the throttle body? I know that the first part of the hose is bigger than the second half. I guess I would have to put a good hose clamp on gutentite on the smaller end.
One side is 3/8" ID the other side is 1/4" ID. 3/8" hose should get you there if you tighten it down good enough on the small side. I used a coupler from a Brewery parts house instead of the one size hose. Hey nyg215, just how big is a reg ol radiator hose anyway?

I did the 'coupler' method and used a 1/4" barbed brass piece, it's tight enough on the 1/4" side obviously but I had to really tightem down the clamps on the 3/8" side.
My question is, am I potentially starving the flow/hurting anything by using that little 1/4" coupler instead of the more commonly used 5/16" one at all?
I have a 3/8" one I could use but it might not fit the smaller 1/4" hose.

I believe I'll try the 3/8th hose. Almost forgot I had started this thread. Duh. Think there's a real hp gain from this? I remember reading on bmr's site a guy picked up 6-7rwhp but I believe it was lt1??? Either way, I'm sure it's worth doing.

That dyno sheet on BMRs site is interesting though, I wonder if someone really showed that kind of gain over multiple dyno runs.
