Sorry for the confusion... I thought the pic of your Dyno run was going to be "quoted". My smart ass remark was targeted at your HP/TQ #'s. I was not implying that there was an inability to strap down the truck. Good luck regrdless, it does seem that you may be one of the "lucky ones" that has a retarded cam issue, rare but it has happened.
mine dynoed a little more than I expected a mostly stock one would. granted a dyno is a tuning tool and dynos vary.. mine put down 445rwhp. the previous owner had it done at Futral Motorsports in Walker, La. they mainly work on GM products so maybe that's why it pulled such a good number lmao. the owner before him brought it to the track and had a best of 12.88@105mph so.. it's a peppy ride for sure.
That's what I would expect a viper engine to do at the wheels, a 48 re will eat more power but not 90 or so more, so I do believe there is something wrong with mine. Off topic dyno post warning . Numbers do vary between different manufacturers , but if you dyno'd on a dynojet and have an sae corrected number, the numbers will be comparable. The good thing about dynojets are they all calibrated to the same standard so they all read very close. I use to have a dynojet 248c before I bought the dynojet 224, the cars I ran on the 248 made the exact same number on the 224xlc, I made a point of testing my super repeatable n/a rx7 on both to test the consistency as advertised by dynojet. When I was shopping before I purchased the 224, I asked all the different manufactures for customer referrals, dynojet came up with a ton. I phoned a dozen or so, a lot of them were racers that travelled around and needed a machine that was consistent with other machines in other places. That's dynojets strongest point, by not offering open software with correction factors, and using fixed inertia's for measurement, they can have consistency. Its like selling tape measures, if you sold ones that are elastic or with moveable markings, how well would that work for uniformity of construction? The beauty of the xlc is it also has load bearing that can be turned off and on for tuning purposes, although the 248c also had load bearing via proportional air braking, so its not really true when people say the that earlier dynojets are inertia only. I load cell tuned a lot of cars with the 248 on the air brakes and it worked fine, it just didn't have real time torque readout like the 224 xlc, and the 248 was a giant machine that took up way to much space compared to the 224 xlc.
Spent some money on the truck yesterday: First round: Magnaflow catback K&N intake Magnecore 8.5 wire set NGK plugs Stoptech cross drilled rotors Green pads That stuff should be here in about 2 weeks. Next on the list : Belanger headers and mids SCT pro racer software SCT x4 flash programmer I'll see where the power is after this, if its still low, I'll degree the cam.
I'm going to be selling my MOPAR headers and mids soon, if you are interested. The Borla cat-back in the pic is already sold.
Yup, interested, could save me some US currency conversion pain.. What are you changing to ? Twin turbo? :chain:
No problem, if they haven't shipped yet, you may be able to reverse the $$ I would want $500.00 CDN + shipping for both.....
MagnaFlow and k&n done. Noisier for sure but seat of the pants feels the same. I will dyno it when I have time, probably in a month or so.
You will see a big difference with part 2 of your performance upgrades you might want to add a ported throttle body and an under drive pulley it's cheap hp for the $$
