TA stage 2 head flow sheet needed

I will like to see a flow sheet of a not ported ta stage 2 head thanks

 

Pretty sure info is available here...try a search...thinking 260-180ish was what was reported.

Good Luck!

 

SE or TE?

 

Show both so we can see the difference.

 

Yes post both one
It's interesting you don't put that kind of info on your site:bla:

 

The high lift flow numbers, out of the box and ported, are listed in the TA catalog. The charts showing the flow numbers at lower lifts are not.

up up i whant that flow sheet :Brow:

 

There's a column on here that has the stock stg 2. It was from a before/after test by Gessler.

 

thanks a lot

 

I`d like to see the Stage 2 SE heads with the big 2.26/1.75 valves unported flow #s.

Thanks

 

Sorry for the wait but tt will be a day or two before I can get down to the shop to find and scan some flow sheets, I have a project for school I need to finish :blast:

 

Thanks I wait :Brow:

 

School is more important.

 

You guys posed a great question, so what I'm going to do is try to find Stage 1/2 SE/TE heads with no porting all the way to CNC porting and make a big spreadsheet. Until then this is the best I could find.

Highlighted numbers are the ones to look at. Intake port numbers should be the same for Stage 2 heads. The exhaust numbers for the SE set are a little higher because we were playing with backcuts, so those are optimal.

Unported (I think) Exhaust Stage 2 numbers on a sheet here are

.050 / 0.100 / 0.200 / 0.300 / 0.400 / 0.450 / 0.500 / 0.550 / 0.600 / 0.650 / 0.700
28.0 / 52.4 / 111.9 / 160.6 / 187.2 / 194.0 / 199.6 / 202.8 / 204.3 / 206.5 / 207.4

George: I saw an unported 2.30 sheet but I cant seem to find it now, but I do know that if you go with a big valve you NEED to get porting because it kills the flow numbers, so they're lower than the unported 2.130 numbers.

 

Thanks for info good thing to know.

 

FYI. These heads were ported to match the TA304S cam.

Here's a Gessler SE stg 2 with level 2 porting I saw this weekend. Intake #'s top row. Exhaust numbers 2nd row.

 

This is TA Stage 2 SE, Gessler level 2 also..

 

Great numbers,i will be sending mine to Greg this winter for level 3 it will be interesting to see the #`s with the big valves.

Thanks

 

thanks for all the help you give me
