True... but it goes goes to show that the blower will loose efficiency after stacking on that much pressure.
Don't get me wrong... I have plans to get one... but I have noticed some people spouting words of high efficiency at high boost.
You have probably seen the extrapolated chart that I sent to LSJwannabe... I think this fits that model pretty close.

 

dropping timing 5-6 degree's across the board, and still getting slight knock up top, not my idea of fun. torque steer half way through third is amusing.

 

The lower pulleys need more meth too. You run a 75/25 mix? What size nozzle?

 

90/10 mix. 5gph nozzle.

 

We had to bump seans car up to a 7gph.

 

how much timing was he trying to run?

 

where and how much did you pay for your tvs blower?

 

i bought mine used from someone in michigan. new they are 2250 i think. somewhere around there.

Ah the days of having retarded EGTs and a slow car.

 

i ran 21* on pump gas with the 2.75" and a 30/70 mix. When i pullied down i had to pull out 5* go up to the 7gph and go with 2step colder plugs.

 

your motor lived due to the pistons in it.

my egt's last night hit 1500 at the top of third. i didn't do that **** again.

sean. i was a bit lower than that on 7's. not much lower, but a bit


you still have that 7? nate still hasn't checked his pm's on here.......

 

yeah still tapped in the intake

 

hmmm. i'll do some iat and idc experiementing before i go up in gph sizes.

NATE CHECK YO PM'S FOO!

 

sometimes i wonder if the cobalts need bigger meth jets as the meth needs to go through the shitty lamenuovas (sp?). I wonder how much of it is just puddled at the bottom of the manifold????

 

according to my calculations he should be running a 7gph. I doubt any of it is puddled, that would be very hard to achieve.

 

area did you fix your lifter issue you had?
