ETP 225's
 

I'm thinking of switching to ETP 225's with a G5X3 114lsa, what do you guys think? By the way I'm new here. Current mods in sig.

I'm currently going through a head swap...Going from TSP stage 2.5 LS6(64cc) to ETP 215(59cc) in conjunction with a G5X3/114.

The last piece to my puzzle is the Vengeance ported Fast that is in transit, and then a dyno tune this coming Friday....

I'll post the results as soon as I get them.

i went from absolute speed stg 2 heads to tsp 2.5 heads and lost some power..switched to etp 215 heads and picked up 40hp over the other heads....this is with the etp at 59cc as well, the cam i have is a .611/.619 242/250 on a lsa of 114
with an a4... so i would say its a good choice to switch to etp....

I love the ET 240's that are on my 402.. pushed my 3580 lb car to 10.80 with the tires spinning, and the rims spinning on the beads..... I'm happy with the results.

Awesome! The guy I talked to at ETP suggested the 225's with a 58cc chamber. BAM-BAM did you have to fly cut?

Anybody else use ETP 225's?

no fly cutting but this is a 383 motor and i have -7cc dish....pistons

ETP 215 at 59cc with a .040 Cometic and G5X3/114 had more than .100 clearance intake, and even more on the exhaust....

Just my .02

Looking forward to your results as I have a similar set-up except my cam is smaller and Fast is unported. No dyno numbers either. :cry:

Provided the intake shows up this coming week, I have a dyno tune session scheduled for Friday....

I will post results here and Corvette Forum...

Take care!

what numbers did you dyno.

If your N/A only with stock cubes i would say stay with the 215 .If you plain on spraying the 225 will shine on over the 215.

Damn bro 9.1's@152mph :eek2: . That's crazy.

I think the whole debate about port size is overrated. The ET 225s would be perfect.

Thanks for all the info guy's! Hopefully I can save the $$ for the ETP's before spring, I really wanna go 10's next year.

I have ETP 225s on a 347. It runs well for what it is now.

Are these numbers locked or unlocked?

locked I'm sure.

What cam do you have?
