Such a great combo and Joe has this dialed in. My 615 SR20 made 1225hp.
I heard that intake above is 6K for 25-30hp and makes less Tq. No thanks on my bracket engine and even less desirable for a T-stop car. It will be interesting to see how it works on the track for the people who buy this....
SC718, you'll have to keep us updated on how it works on the 9 deg engine.

tony i had a SRE 674 before this 615 that was excellent i just decided i didn,t need to ride that fast anymore. this 615 hit the same numbers as yours and it will get your attention even leaving in high gear lol . the 665 nine degree stuff is close to 1400 with 2 carbs but add exponential dollars ....

Tony,
I will keep everyone updated. I was very impressed with the power it made. With the 1450 carb it made 1337 hp at 7800 rpm and with the 1650 carb it makes 1378 at 7800 rpm.

You need a TMC 2000 CFM twin blade on that motor!

I'm right with you, had a SRE 648 9 deg but it was much more than I needed for what I want to do.This message has been edited. Last edited by: TonyB6255,
