The folks at ProCharger are very excited about these results with the D-1SC.

Yeah, we're already talking about 305's front to rear. I might cheat though and get 315's in the rear for a little extra style.

Hey Allan, Didn't see your post; It was an honour meeting you as well, and getting a close up view of that new motor you just slapped in. Man, it's going to blow your mind. LOL

Saw the vert today at the shop, waiting for that final touch eh?

Soon, we can roll with the rest of the bunch.

We installed a new slave cylinder, and bearing. Seems to be something that happens occasionally (for some) when changing to an aftermarket clutch (of course would happen to me because I'm so extreme).

We should be fine now.

If you have any questions you know where to reach me, more than happy to help out. BTW - Touched base with Chris, that will be the next mod.

Chris, you got an awesome build going on up north there! Good on Ya! Glad you got the clutch figured out. And even better for calling Chris for your real needs, you will need alot of power to break it, and if you do, Chris will take care of it. Im sending you an email from my home email, obviously you haven't received them. It looks like the AirForce is blocking anything out of country.....you may be a terrorist! Damn Canadian suicide bombers!!!

Congrats buddy, been a long wait. When the weather warms up go slow and learn the car. That's an insane amount of power, not the same car anymore.

[calbert1999]

Still have to get some more decent pictures (waiting for nicer weather), then thinking I'll do a build journal now that I'm pretty much finished. But, for now check out the engine bay.

We did all the cool stuff.

Just went thru this thread again since our builds are pretty similar. I will be running the huge fuel Aeromotive fuel system feeding the ID1000s so fueling wont be an issue.

Spoke with my shop today and he anticipates the motor should be around 520 or so rwhp NA with the huge flowing Mast blacklabel 305 LS7 12 deg heads and PatG 231/246 .675/.652 116LSA +4 with 1.8 rockers and static CR of 9.4:1

He said a rule of thumb for boost is for every 8 psi add 100hp and for the additional 4 psi, add another 40 or so hp. So at 12 psi should see at least 660 rwhp and said this was probably pretty conservative.

I am anticipating more like 750 or so to the rears with the D1 nearing max spin. Maybe a little more. We will see I guess

I have always been pretty close in predicting number with boost by using 1 psi as 6.8% of one atmosphere at sea level. 12 psi is roughly 81% of one atomosphere. I am sure there is some loss based on the bigger cubes and CFM but by doing the math 520 * .81 = 421hp from boost. Then take away 100 for inaccuracies, parasitic drag to spin the D1 etc. So about 300 whp to the wheels or 820 or so RWHP on the dyno assuming the D1 will give me 12psi with the free breathing motor. This formula worked spot on when adding my D1 to the LS3 and also was spot on with upping the boost from 7 to 12 on the stock motor.

We will see. No plans to run the car on the strip so the dyno numbers is all I have to go on.

Anyone have any thoughts?

8 psi only adds 100RWHP on a big high flowing modded LS7? I would think it would be way more than that. 8psi on that kind of motor might be 13 psi on a stock 6.2.

BullF-16 you have way too many equations for me to think thru but you sound like you know what you are talking about so I am with you that for the mods, the hp predicted sounds right.

Yea, its kind of a combo of thermodynamics and fluid dynamics with air being the fluid. It was pretty accurate with my LS3.. Back then I figured with 7 psi added with the install of my D1 on the LS3 i would get just under 50% increase in rwhp. I was at 440rwhp with the cam and headers/tune and a 47% increase to the the 1/2 atmosphere from the boost i would be at 646 rwhp. Well on the dyno we hit 637 at 7psi so pretty close.

Then i figured that when upping the boost to 11psi that was 74.8% of an atmosphere, so 440*.74 =765rwhp. On the dyno i was at 715 rwhp. so a little more loss that i think is due parasitic drag caused in part by the motor having to spin the D1 quite a bit faster.

I dont know how accurate my predictions will be on the new setup but if it is about 515 rwhp on the LSX and 12 psi (if i can get that) 515 * .81 = 407 add'l hp thru boost. so about 922 then subtract a hundred for turning the blower near max rpm to get the 12 psi on a free flowing motor. So i predict about 800 or just a bit more on the dyno.....we'll see

Anything more that 750 and i will be pretty happy. Not a racer so dyno numbers are all i have. Got enough competitive hobbies that keep me stressed out.

One other thought i have been having about the big F1x and F2 blowers at 20 or so psi. It takes quite a bit of motor to turn that large chunk of spinning impeller that fast? So increases to the chassis dyno are not quite as big as for a smaller blower? Remember, i dont know what the hell im talking about here....its just me thinking out loud so flame away

It takes the perfect combo for engine and blower to maximize results. I thought that the LSX427 I had would be a good fit for the F1R but come to find out it was too much motor for the blower and I could only get 18psi out of the F1R as it was spinning at max rpm. With my current build, the motor was completely rebuilt from the ground up to specifically maximize the F2 so it should be very impressive.

How could the LSX427 be too much motor, I would think you need a large motor to deal with the huge ProCharger?

Oh, man I can't wait to see the results. You're build is very similar to mine, only different heads and CAM I think is slightly different on the LSA I think mine is 114. You are going to be pleasantly surprised especially considering you have a beefier fuel system than I do. I could not feed the engine enough gasoline with the #85 injectors and the dual fuel pump, so we could only get up to 6k/rpm. on the ideal tune before we ran out. Poor thing' detuned. LOL
