P.S. on 91 octane

 

Need more details Heath.... 370 ci's????? what kit??? pulley sizes and how much boost???Peak RPM?? Come on man.....
Kyle

 

I copied this from Rick's original post on our board:

I like the fact it was 91 octane. That's crazy.

BTW, I was checkin out your car in the LS1Tech calander last night. My buddy has the GTO in it and brought it buy for us to see. Car looks clean bro

 

Nice numbers to say the least.

 

With the stock stroke and the 4.030 bore, I think I remember calculating something around 370 CI's. The head unit is an ATI D1SC with out custom front mount and custom piping. Mondo Bypass valve. SDCE 8 rib setup. And about 13psi we saw on the dyno and on the street.

 

Nice job on the numbers white boy. I should be at the shop tomorrow.

 

What are those numbers corrected since that figure is actual hp not SAE? It also looks like your peak hp # was recorded on a small spike from hitting the rev limiter, so the car is making about 670rwhp uncorrected.


Still badass #'s for 13psi!

 

Congrats! Very impressive Good luck hitting your 750rwhp or higher goal.

 

ahhhh man I wanted to make these guys suffer for a while with no details

it's basically what you have kyle. sd pulleys, obx ic, ati d1, plus a bitchen motor

 

Thanks man.... i oly knew my pic... i didnt know who else was in there until mine showe dup at my house..... i ordered 4 ha ha

 

Can you tell me little things since this car and mine are so close...... what size blower pulley?? Im running a 3.4" NOW BUT A 3.3" is in the mail... what cam?? if its custom i understand.. mine is a 230/236 .598.608 on a 114+4 so is it close to mine??
6.0l heads i take it?? What compression?? Thats using the Vortech Mondo bypass??? Thats what i have on order.... what drive train?? I take it M6.... how high were you spinning the motor will really help me out....??
Thanks
Kyle

 

Pretty sure it's the 3.7 pulley Kyle, I could be wrong though, they may have changed it since I last saw the car, have to wait for Rick to chime in. Mondo bypass for sheezy. M6 with a 12bolt. Heads and Cam Rick has the details. I do know they are both Synergy specs, not just off the shelf. Compression is 9:1. Didn't ask him how high he spun it.

 

It axtually didnt spike until the last run. The Wideband machine was frekaing out on a few other runs, but within 5 HP on other runs, she stayed flat and still made almost 687hp.

Corrected was 670, uncorrected was 687 which is what he drives around everyday on.

Rick

 

The heads are 6L of course, but on the heads I dumped all the money and research into the exhaust. I wasnt realy shooting for anything in the intake. I wanted exhaust. I think I hit upwards of like 86-89% intake to exhaust ratio. I wanted this motor to be as efficient as possible. I even gained around 40-50 average CFM all the way through the exhaust flow. Compression is 9:1 yes. The pistons are diamond with a coated top. manley rods, 6.125. Stock 6.0L crank. Stock 6.0L gaskets, ARP studs of course on main and heads. We ground a 224/232 cam for this app with a 116LSA and a 558/568 lift. I was shooting for closing the exhaust valve later. the valves are Ferrea with a backside radius on the exhaust valve.

Blower, D1SC, 3.4 pulley If I remember correctly.
OBX IC wth Mondo Bypass, Custom piping.

If it is a 3.4 pulley, then the 3.2 or even a 3.0 is on its way after today.

Rick

 

isn't it the 3.7 cause we were thinking of swaping it with my 3.4 at one time????

 

I have the 3.4" now but i havent put the pedal to the floor yet because of tuning. Im still tuned for the 3.7" pulley.....and the stock twins. I dont even think im going to tune with the 3.4" since i have a 3.3" in the mail to me..
I know that a 3.4" pulley is the smallest you can buy from ATI.... but you can get a 3.3" and a 3.2" from Richard Racing... How big is the piping?? 3"?? How high are you spinning the blower also becaus ei would like to figure out how fast you are spinning the blower.
Thanks
Kyle

 

Rev limiter is set @6500, so we spun it to that.

Rick

 

Thanks Rick..... you have got me really excited........ because your spinning the blower to 56,827.... and ill be spinning mine at 59,450..... Ill be happy with 650rwhp corrected. Two more questions and im done......
What Size Injectors and what fuel pumps??
Thanks
Kyle

 

He has the auromotive fuel setup with the 1000hp pump. If I remember correctly he has the seimens 58lb injectors I think. I have to go look back at the logs from the dyno to see what duty cycle we hit, we just might have to step it up a notch....again.

 

Hey Rick ... you guys put some sweet numbers out. I'm in Cali, can you PM a price of that motor. I already have the SC, intercooler, bypass, etc

thanks
