A.I. 21* HCI package
#21
I ran 13.2 with boltons and havnt made a clean pass in the car with the current combo. It ran a 13.2 as well but still in second gear. I had a miss and a dying fuel pump. I now have a smaller cam motion cam in my current motor and plan to go to the track thursday to get a good pass and have something to compare to. The 23* heads didnt have the comp. to work well with the big cam LE gave me.

Cool I also just got some 21 degree trickflow heads. LE did the porting on mine though also got a cam from him. Nice to see these heads making power. I cant wait till my new engine is done.

Duty cycle is kept to around 80% because it is the time available for the injectors to get fuel into the cylinder. It has nothing to do with keeping the injectors cool. And there are many cars tuned running 95%DC at redline.

If building a salt car or standing mile car overheating injectors might be a concern, for a street strip car, I don't believe it is. If you talk to a Stock Eliminator driver they actually can give you reasons for running the DC as HIGH as possible.

Not to much lol im still slow for atleast a few more months. Im selling the whole motor or parting it out. No bites yet. Selling the 4l60e and 4400 vig stall. I plan on taking it to the street heat event next month at BMP. Im not pulling it till it sells or im done building the new one. Hell its decent i might fin d a clean m6 and make fun third car. Who knows i have a.d.d.

185 to 212 cc only 3cc less than the 195s to 215. Not sure how much actually 21* helps vs 23* if it makes up for the slightly smaller ports. While the motor and trans is out I'm gonna see how creative I can get with the weight reduction. Shooting for 10' on motor.
