I guess it's not that noticeable like you said but was hoping for less rpm's to get into boost off the line. I was told the outside edge of the turbine wheel will spin faster than the inside.

I don't believe there is a data logger for my car, I'm still using the OB1 ecm. The reason I chose this quick spool valve is that it is made to be used with a divided manifold. I thought the spool time from idle rpm to boost rpm would also be effected. I was just curious if anyone had any real...

I purchased a T4, V2, Quick scroll valve from Diesel Pump UK, good quality part. Quick Spool Valve V2 – Water cooled I installed it on my camaro V6 3.5 liter chevy engine. I have a twin scroll Borg Warner, 66mm turbo with a divided manifold. Water lines installed, flapper valve is mounted...

Did the trick with the shop vac, I couldn't believe how many exhaust leaks I had pre turbo. I've used this method before to check the cold side but never thought about the hot side.

Your exactly right, that's what I bought it for but never used it for that purpose. Just happen to work perfect for this application. Cracking pressure is so low you can blow through it.

No problem, here are some pics of the check valve I used.

I integrated this set up https://grannys.tripod.com/evac.html and now have crankcase vacuum even when not in boost. I had to add a large check valve right before the air pump so the pcv would not breath through the pump. I only run an oil separator on the pcv side, so far the air pump side is...

I took the car for a test drive, under boost I am now pulling 5HG. I have my pump set to come on as soon as it goes into boost, since there is a ramp up time until the vacuum hits.

My pump did not have a diaphragm, I only had to remove the foam filter. Pump and pcv seems to be working correct now. I will be running a vacuum gauge to the crankcase and taking it for a test drive. Thanks for your help.

I think I discovered my problem, as you stated I blocked off the fresh air when I added a large check valve (over thinking) before the air pump. Correct me if I'm wrong but the pcv gets it's fresh air through the air pump?

Oldie but goodie post. I ended up installing one of these pumps with the two wires on my car. I initially had one breather on the valve cover. The pump was used to pull crankcase vapors only in boost, and pcv was left in. I then decided to remove breather from valve cover and plug hole. Now I...

It's been on my mind lately to replace the pump before it's too late, I guess I got my monies worth out of it.

I've had the same pump in my car for over 12 years and never replaced it or rebuilt it. I normally run a 50/50 mix and have never drained it. Does the water mix protect the pump that much or am I just lucky?

Nice looking car. Making me miss my paxton 88 GT Stang right about now. Good luck with the sale.

For sale a 3.4 liter crate engine, part number 12363230. Motor only has 3,000 miles on it. I bought this crate motor new 11/18/10. It was installed in my 94 Camaro which is only used on weekends. I decided to do an engine swap 11/23/11 and removed the engine. I have the receipt for the engine...

Raising the dead here but is this a good method to get rid of false knock? Has anyone else tried doing this? If the sensor is in lose what keeps it from screwing out? :confused:

I've been hunting this knock problem for awhile now. I went through the knock list and as I was checking the exhaust system I noticed when I punched the muffler there was a loud vibration coming from inside the muffler. I'm quessing a baffle inside came lose and is causing the problem. I...

Check out this retro hybrid. Chevy 789 - snopes.com

Tps sensor could be bad it may have a bad spot at 3/4 throttle.

Congrats on hitting the 12's. You know you won't be satisfied for long!
