The Cam is a very nice looking piece. They made it and had it to me within a week. They ask 100's of questions so be ready! The car sounds outstanding and is making good power with it. The cam is a hydraulic roller. I am running Morel Hydraulic roller lifters to keep the valve train in check.

I have not had a chance yet, but on the dyno the temps were 110-115 and it was 80-85 in the shop.

How many degrees were you thinking? The motor is 9:1

ours is 9:1 also but we run q16 with 20psi at 37*.
(sea level/with lots of humidity.)
keep a close eye on your inlet temps. we ran that same pump at 16v and it could not keep up. we switch to a rule 2k with -16 lines. man what a difference that made. the temps at the end of the run were in the mid 90's instead of 140 range. we are in the process of putting a lot bigger cooler in hopes of getting the temps to stay in the 60*range.

Could you share some more information on the setup you are running? 37* is some serious timing in a HP boost motor! I've never ran that much in anything that had a power adder. **** my base timing for cruise is only 36* haha Thanks for any insight.

nothing special. 383 with afr210's and a ysi. cam is a custom crower but we have run the same timing with a off the shelf comp 468 grind. biggest things to watch is weather(water gpp) and air inlet temp. if you start off easy and work your way up nice and easy you should be able to find out what your combination will let you get away with. also don't underestimate how much fuel its going to want.

You aren't running a filled block or anything? I see you are spinning it up there pretty good as well. I was only taking this combo to 6100 on the dyno, due to how the piston was made Boost/Nitrous combo, the piston is heavy so I am only going to spin the motor to 6500 per the recommendation of the builder. He said I could spin the Motor to 6700 but the extra stress on the parts wouldn't be advised.

What kind of power are you making with your setup? To run the times you are running with the MPH I would guess 1100-1200 rwhp unless the car is super light and efficient.

no fill. if you keep the rpm down it should live a long time if the tune is right.
power wise. i don't know. we dont do much dyno runs. we prefer the track.
the car is 3500lbs with me in it. best mph was 154.xx

You and me both buddy .

Not for max power for me though, just for more cubes and NA power...

With that weight and MPH you're around 1000-1100rwhp. Who is the tuner of your car? Id like to discuss some things with that person if possible. I know this F1a isn't going to make 20 psi. Ill be lucky to get 15 out of it. so I should be in the 800ish range I hope. I was looking at adding one of these units since the FAST does not have knock control. Have you ever seen one?

The 03-04 Cobra guys use them and have great success.

Are those custom kooks? I really wish Kooks made a bigger off the shelf header for our cars, even if it needed flange adapters. They are freaking beautiful.

These are off the shelf version I was going to go with the 3 1/2 collectors but I was able to get such a great deal on these I couldn't justify the extra cost. They fit awesome and the spark plug access is pretty damn good too for an LT1 car. I have zero complaints about them.

I handle the tuning and pretty much everything else. As for the knock control. I don't have any experience with them.

question about your passenger side valve cover. Who makes those? Did it come recessed like that? The reason I ask, is that runs a passenger side ysi trim vortech on my c4 and I had to clearance the valve cover to get it to not hit the volute. A valve cover like yours would work awesome for me.

They look like Cantons, they come recessed.

I ran them as well

They are polished canton covers. They work and look excellent. No leaks no BS they just fit and do their job.

How are you only making 12 psi of boost with an 80/40 combo?? On my old setup I was running a 77/48 with the exact same blower and my motor was close to yours but a little less compression it made 17psi at 6700 rpm. It sounds like you are cavitating the blower, and its not making the boost it should. I dont think speeding up the blower will help you any, but I could be wrong.
