Hey guys,

I just did a new Shelby again but this time with a JLT intake and a 2.6 pulley. We installed it all on the dyno and got some good results.

For the baseline we made 430 rwhp and 426 rwtq.

With the tune we made 471rwhp and 455 rwtq, overall a gain of 41 rwhp and 29 rwtq but the gains in the midrange were 30-35 ftlbs of torque and ranged from 40-45hp.

Next we added the JLT and I developed a tune for it. This was a nice gain as we saw 502 rwhp and 476 twtq. Another gain of 33rwhp and 26 rwtq, now we're at 72 rwhp and 50 rwtq with just the addition of a CAI and tune.

Finally we jumped in on the pulley, 3 cussing, cuting, and fighting the pulley off hours later we had the 2.6 Metco pulley install. The boost went from 9psi to 14psi, as we had a manual boost guage connected to it.

The Max numbers only went to 522rwhp and 528 rwtq but it had gains of 35hp and 64Tq@3000 rpms, 41hp and 53tq@4000rpms, and 41hp and 43Tq @5000 rpm's over just the tune and the JLT intake.

There are points on the graph where it made more then 110rwtq more then stock!!

I figure a few things were going on here. One, heat, we made about 4 runs before we were solid on the a/f enough to get a run number and these engines hate heat. If we had let it cool off for 30minutes to an hour it probalby would have went to 540 rwhp easy.

Two, the exhaust maybe starting to become something of a restriction? Now this is my opinion! He has a completely stock car except for the addition of the intake and pulley.

Still, with just the addition of an intake making gains of 70rwhp is just crazy, these cars are so unfair! hahahaa. Afterwards on the test drive it was a beast, and you could hear the air coming into the huge cone filter now as well.

Thanks Doug.

 

Great job Doug! It is simply amazing to see what bolt ons and proffesional tuning can do with these cars.

I wanna compliment you on thanking your customers for your success. That is very classy. Keep up the good work

 

holy crap! those are some insane numbers

 

And that is where the seat of the pants will be most noticable. That car will really pull.

Doug, I am about 8-10 months from getting my car. I will likely be contacting you shortly thereafter. Do you have contact info?

Nice work. Can't wait to see if you get better numbers cooled down.

 

Wow! 70 hp with just two bolt-ons

Sure, you can reach me at BamaChips@gmail.com or 205-302-0231 is my business line.

His next step is longtube headers, this should get interesting

 

What is the deal with removing pulley? Not aware of this.

 

the car is already supposed to have 500 hp... what's the deal?

 

that's 500hp at the flywheel, the numbers he's giving are at the rear wheels.

I think.

 

The advertised numbers on the cars are 500hp, and that is meaning 500 at the crank. What Doug is showing here is rwhp (Rear Wheel Hp) numbers, which is significantly lower due to drivetrain loss. The numbers he is showing on the baseline with the 15% drivetrain loss, is right at 500hp. If you calculate the bhp number off of the 522rwhp he posted, you'r hitting right on 600hp at the crank

Remember, all those huge numbers at the crank dont mean squat except on paper... you gotta put it on the ground first and then you know what you really have

 

Nice numbers Doug . Looking forward to seeing what the LTs will do.
