Stay tuned for some interesting Dyno tests.
- Thread starter Otto J
- Start date
Car #2 put down 605 at 5700 today, torque was 586 right out to 5500 or so,boost at 28#s, pump gas, dual nozzle ALKYCONTROL.
The injector duty cycle according to the XFI was only at 55% with a single Aeromotive intank pump.
Tune is conservative at 18* timing a/f in the high 10s
With the new PTC convertor installed the dyno showed an improvement
of 16 MPH at 5700 RPM.
It was still picking up 25 RWHP per # of boost but being the short block is all stock components i stopped at 28.
We are thinking about putting in C16 and turning it up
Not sure I can recommend that

Car number 3 is coming up.
I hope to have it running by next weekend,but it is a bit of a project and I am waiting on parts.
There is a car added to the mix though with a comp turbo 72MM Xtrim that may get a new Precision unit,not sure on the change yet,but will be doing back to back PTC convertor replacement on this car also this week.

Don't be a sissy Otto- turn that sucker up! Put some C16 in there, set the timing at 21*, turn the boost to 30# and let it eat. It'll survive one pull............You are a good tuner aren't you?
:biggrin:LOL, I am all for it Will, but the owner bought the car stock and dropped it off,he wanted to drive and enjoy it a bit before we really let it eat.Don't be a sissy Otto- turn that sucker up!

It is going to JW Racing and Fabrication soon for a mini tub,cage install.
He bought the aluminum budnik wheels,10" for the rear with 325 50 radials.
Trans is all stock with a shift kit/servo/PTC convertor,its on borrowed time...
At what boost level did it start to pick up 25 RWHP per # of boost? Thanks

It could last years like that or 300'. You never know what you will get. The stock shortblock will take it for a while. You don't really know how hard it was run prior to cranking it up. If it was reltively stock/low rpm and not detonated it would likely stand a chance at lasting longer than one run in the grenade mode for years prior.

how about 450 rwhp @ 15#s with 20* timing?
There's your teaser
wow!!!
Is 22#s considered turnned up???
I stopped at 22.3#s because it already was making 612HP to the tires, and to make it even sweeter, the motor only needs to turn 5400 RPM to do it
This will be the funnest street Buick I have put together,it spools FAST!!
How about a little insight on the stroker????????
