Very nice, are you sure about the duty cycle? 650hp with 25% duty is almost 2000hp at 75% duty (assuming the flow is linear) that cant be right.... not with Corn.

I wish I had E98 locally I would be all over that ish

 

In aem datalogs it peeks at 23% and on ectune datalogs it shows 30%.Static fuel pressure is at 43 psi.

 

Looking to get ID1000cc injectors, although I have read of some users having problems with these injectors during hot starts. They suspect vapor lock inside injector.

Can someone shed some light on this issue?

The 'hot start issue' is not injector related, it's car/ecu related. The cars that randomly have those problems are on stock ecu/reflash stuff where there is very limited control over cranking/cold start/etc.

 

i switched from 1600 injectors to these 2000 injectors and there are worlds of difference!!!! only problem we are running into is if you are running q16 they are only good for up to 800hp on c16 they are good to 1000hp.... why i dont know.... they are telling me it has something to do with the plastic on the inside of the injector restricts the flow because of the oxygenated fuel..... but i still love these things!!!

 

what setup and what idle afr are you seeing?
Looking to get these to run on corn, evo guys are running over 800whp on corn with these!

I was using 880cc delphis and had somewhat choppy iddle at 13.8-14.5 afr bouncing at 1000rpm, any lower the car would hunt badly. This was on pump fuel.

Ok just saw the vid above answered my question somewhat, 13afr at idle not bad. We want something between 1000cc x 2000cc now T1! Any plans on a 1500cc injector? I would assume this is a special order injector from Bosch?

 

but there are a few of these cars that are not having the problem on that same ecu platform with minimal-to-no tuning to the start-up fueling tables.

Also the complete start-up fueling routine has been found in the evo rom and there is 100% control over the start-up fueling which has not even made a slight difference in the warm start-up issues.

 

There have also been guys that have swapped injectors from cars that started fine and cars that didn't and the problem stuck with the car, not the injectors.
