Re: 11:1 CR Race/Street Engine build

Honestly, not 100% sure but I think it may have been related to a weak battery w/ a weak starter not turning the engine fast enough. Finally caught combustion but might have a little too much timing at that particular time and kicked back (slow motion detonation).

I need to replace the battery still but I did get a new starter in it and cranks over perfectly now as long as it is on the charger.

Pics of the pulley, never got pics of the cam. You can clearly seen it didn't "wear" like they usually do, this was a single very strong abrupt force


Pics of the thermostat inline


and the lights installed



That is all for now... I am itching to get her up on the dyno now

Tom

Re: 11:1 CR Race/Street Engine build

ouch with the pulley!

think there is anyway to make that inline 'stat work with the stock pieces (assuming you can cut the upper hose into two pieces)?

Re: 11:1 CR Race/Street Engine build

LED programmed into one of the aux ports of the Hydra?

What RPM does it light up at?

Pretty neat and clean!

Re: 11:1 CR Race/Street Engine build

6500 rpm. Gives me some space to shift under full acceleration.

Re: 11:1 CR Race/Street Engine build

I have it set to 6800RPM right now... Lets see exactly where the power band is on the motor and we can make a final decision from there

Re: 11:1 CR Race/Street Engine build

Tom how many crank rotations have you got it set up to, before the ignition/fuel starts.

Re: 11:1 CR Race/Street Engine build

not really how it works... Basically it takes until the positions sensors learn when the engine is... Meaining the cam sensor needs to trip once before the ignition will fire

Re: 11:1 CR Race/Street Engine build

Tom,

Has the Hydra got an autotune function?

Re: 11:1 CR Race/Street Engine build

yes, but you need to have it setup for VE tuning not millisecond fuel tuning which is what I have been running

Most of the units allow 6 crank rotations before the ignition is enabled. Lets the starter get the crank up to speed, before it is allowed to fire. I believe the standard unit does that.

Re: 11:1 CR Race/Street Engine build

I find it very hard to believe the stock ECU allows 6 crankshaft revolutions before ignition. Not to mention, the Hydra has always allowed more time cranking than the stock ECU, not just on this engine

Re: 11:1 CR Race/Street Engine build

My engine cranks 6 times at most before starting, generally 4 or 5 times, sometimes only once or twice.

Re: 11:1 CR Race/Street Engine build

Ah, gotcha. Although wouldn't 6 revolutions mean only 18 compressions, since the compression stroke occurs every other revolution?
