Post your Boost PSI at WOT!!

[blackgn1]

Who's pushing it to the edge? How much boost are you running?

 

[Grumpy]

TSM boost = 24#s

 

[slimtastic]

20 psi when its hot outside 21 psi when its cooler at night.....pump gas no alky, thats right im stupid

 

[blackgn1]

That's funny. How much boost were you guys running when Melissa ran the 9 second pass. I know it was higher than 18psi and lower than 40psi. The world may never know. And while we are talking TSM you guys are more than welcome to post your boost pressures. I will wait for your answers. HAHAHA!!!!

 

[blackgn1]

I'm at 26psi with a 6776 H cover. With dual nozzle alky.

28psi in average air. 30-32psi in really good air. Boost doesn't break engines. Mass flow makes power. Not necessarily boost.

Thumbs up on Bison. I knew you were on the high side. Youv'e got a good clean tune. Aminga.....oh ya!!!!!

 

[slick6732]

23# Pump gas and alky, single nozzle

 

[INEEDAGN]

I can do 18#on 91 in most atmospheric conditions. I usually don't, simply because I never drive the damn thing and it's always on last years gas it seems.

No alky, 44 turbo, stock IC, trans plus/extender setup

 

[turb0buick57]

23-24lbs normally on stock longblock ta49 93 and alky. Trying to inch it up around 25 this year.

 

[kidglok]

best was 11.3 @119, 23psi on a 60-1 compressor. She had a lot more in her if "other" things were in order

I am only running 21PSI right now. I can easily put it in the 25+ range if I could get the wastegate to stay closed. Adding a manual boost controller should fix my issues. Hopefully it will be coming this weekend! 6131E Turbo, stock engine (except valve springs and timing chain).

 

[TARZAN]

23/24 lbs off the bottle, 27 on 100 shot

-Will

 

[Boost231]

atleast 28+

 

[ZNix]

atleast 28+

E85 right? Wish I could get that stuff around here.. Would be awesome!

 

[Boost231]

C16, Turbo is out of steam at 25psi

 

[kidglok]

what is "boost", isnt that whats measured as not getting into the motor?

Keep in mind that one engine might need 30psi in decent air to move 60lbs/min and one might need 20psi to move 60lbs/min. They are both going to make about the same power and as far as tune goes either one could be hurt just as easy as the other. Scrimping on octane and getting greedy with timing will bite you in the ass. Fwiw the #'s i posted are on 93/alky. About 80lbs/min in good air. Richer than would be expected target and lots of fuel. Two 10gph nozzles. Not a 10 and a 15 like most would think.

Not a good definition by any means but it is manifold pressure and nothing more than that. Mass flow is what's getting in.
