Here's a side by side from the street port to the brideport at approx. 6-8psi less. The brideport not only makes more power across the board, but its a much smoother pull.

congratulations to you. very, very impressive, but i guess i expected it from all the "subtle" hints you (and others) were dropping.

one question though, and i want to hear this from the perspective of enjoying the car as fun transportation (you know, like the Adirondacks, Deal's Gap, Pacific Highway, the Florida Keys, etc.) do you prefer this motor or your last one? i know it will be hard to ignore the new numbers, the new plot, the new people on the jock for full bridgeys, and of course the thinner neighborhood you've moved into, but just think about it and give me as honest an answer as you can. either way, it's yours and a job well done.

and

Looks like you better be paying attention between 5-6k rpm and have both hands on the wheel. Congrats to you and Ray. I'm a big fan of Ray's tuning abilities since he set my TT car up. It's quicker than many (smaller than yours) single turbos.

Meh - Ernie you know your port wasn't all that big before your new BP. Even going with a larger street port probably would have yielded similar numbers =P

Don't worry... I'll be up there with you soon... =)

Yes, its the E-shaft from Rotary Extreme in Australia. This was done on C116 turbo only! As far as making this power on the street port, I seriously doubt it. Especially seeing how the power just keeps climbing and staying up across the whole board. Ray made my street port as big as it could go so Im confident with the bridgeport. It made a believer out of me, without a doubt! Im racing it this weekend at Battle of the Imports with a new "STOCK" tranny. See if I can get an all turbo, stock tranny record, lol...

zinx: You are correct. It is VP-Racing's C16 which is 116-118octane I believe.

Dee,

Don't bring your garbage into someone else's thread.

Rice was right. You hit a high peak boost and tapered off to your final boost number. It is a fact proven by your own dyno chart. Do you deny the facts?

Sorry Ernie. Nice job and great job to every involved in building and tuning the engine. Not to mention you for paying for it all. Trailblazing!

Congrats Ernie on the new numbers !!!
2 thumbs up for Ray !!!!
You're simply making it harder on yourself to get that car down the 1/4 on full throttle :-) !!!!!!!

Just wondering, where do you get 6-8psi less?
Since your SP dyno(711rwh) clearly shows 36psi and you say your BP dyno (735rwh) was @ 32psi...
Is it possible to get that 735rwh dyno sheet with the boost graph ?

Those 2 dyno sheets seem ideal to compare spool-up and gains since nothing else was changed but the porting.

Good luck this weekend......might be doing more drifting then drag racing -)
