Looking for 1 or 2 damaged/unusable 2.5L heads. Bent valves or cracked exhaust ports ideal. Looking to do some flow testing. Looking for them on the cheap

Darwantae951

Would they for some reason by damaged in the process? If not you can have mine for the purpose of testing if you send it back when you're done.

refresh951

Thanks Darwin. But yes, they will be damaged. I will be looking at different port shapes and then flow testing them.

I would expect Lart to have many such heads.

lart951

I have bare heads no valves nothing

refresh951

Lart,

That should be fine. I do not need the valves, springs, ect. They just need to be not ported (stock).

lart951

Ok you have my direct email right?

how about testing this one

refresh951

Lart - that will do Email on the way!.

Be interesting if you can test a stock 2.5 and a 2.7 back to back?

Reimu

I'll give you one free if I can ship 2 and one comes back with a good porting job

refresh951

I found a couple. Thanks guys.

carlege

how are you testing them? on a port by port shape/size basis. I guess what i am saying is could you not test 4 different flow characteristics on 1 head by experimenting each port and testing independently?

If there a machine that can do that

refresh951

Most definitely you can test each port individually. My phase I setup will look similar to this:

...but it will be Arduino powered

Once I get something I am fairly happy with I will take it to my guy to test on his SuperFlow bench.

Awesome Shawn! I am very interested to learn what you discover.

Please keep us posted.

Thank you
