Well it made 706 rwhp. Then it ate the belt.
Any idea why it ate the belt? Alignment issue? Did you do crank gear or oil pump gears?
We will do the gears next. I think the belt was too tight and a little out of alignment.
Do you happen to know how fast you're spinning the F1? Was the plan to go higher than 706?
It's turning about 60000 rpm with the 5" pulley. I think we are going to stop where we are. Everything is still stock even the exhaust. Well, Except the blower, injectors and the method kit.
I know of a few 15 motors holding 750-800rwhp and get raced every weekend. Even highway pulls which are hard on the motors. I would have no problem doing 750rwhp with a blower, and slightly more with turbos.
Who has that much hp at the wheels and runs it every weekend? On a stock motor. And doesn't own a shop, and doesn't have a sponsorship wrap on the car.
750 at the wheel is a time bomb period. It will blow
I know LOTS of non shop owned 11-14 running 750 to the tire on stock shortblock. They just run different valve springs.
Lots of boss cars are 800+rwhp.... I know a few living on the edge of 1000...
Now all these cars are on E-85, so the tunes are very safe.
The boost works KB package is around 700rwhp on auto cars, and a little more on manual on 93 pump and have been living.
Do you think the 2015 motor is as strong as a Boss motor?
Here's a finish pic.
over 800whp here and still going strong.
That is a bad ass car. You made the right choice going straight to the big centri. Get her in the 9s!
What power adder do you have? 800 has to be crazy on the street. Sounds fun.
d1 stage 2 on e85
I had a JPC kit on stock Rods and Piston 13Boss. Near 900rwhp, tuned by TSS. I survived TX2K and I'll be the first to say 8xx is now boring on the streets and it's time to move on. Complete new build for mine, I'll be doing everything I can to be competitive with RWD cars come TX2K16.
If think u will enjoy X and then u get X and find out it's just not enough. Always build for the future if u have the funds.
The 12-13 Boss pistons are better but so long as ur tunes spot on u r good. I have a buddy pushing near 900rwhp on a stock 11-14 GT and it survived but the OPG did not.
Is the Oil Pump Gear the same in the 2015's?
The 2015 gears are powdered metal, stronger replacements would be advised.
Thanks for the info.
Here's a pic of the dyno graph.
Who tuned the car?
