It doesn't drop off as much as it looks......again, it is because of the different values of the left and right axises (sp?) of the graph that throw off the way the graph looks. the same goes for what looks like the car is making more HP than TQ below 5252, also.
for example, look at 3000 rpms. It looks like the engine is making more HP than TQ, but if you look at how the values on each side of the graph, you'll see that: at 3000 rpm, HP is approx. 150hp , while TQ is approx. 285 ftlb.

I just cannot see a standard clutch holding that much TQ. Did your clutch hold because of the kind of dyno you used ?

conflicting info here xkr makes 558 rwhp 564 tq (per his sig)
plus i know another car by FP that puts 550whp too with the RPS max 6-puck clutcha nd flywheel all day long with no issues so far
so....
EDIT
but the i dont believe the jwt can handle 600+whp or the 550whp with track use...
but it happens to be what mike b runs

ovbiously not a huge offence... but that was targeted to the clutch itself

As for the clutch. It is a standard organic style that has been in the car for almost two years. I am just as surprised as anyone about what it has withstood. I would not recomend this type clutch for more than 600 tq/hp but, my only point was that these clutches are under-rated.
As for this car, yes, this car IS making 700 whp at 18psi with the JWT 850BB kit and even 749 at 20psi. wether people want to believe it or not. And for the record this car DOES have the stock type head studs and head gasket It always has. Not the pretiest dyno chart but we were not finished with this car at this point, that chart was only posted to illistrate the clutch slipping, not to be disected.
And lastly, the JWT Dyno (aka the moon dyno) is every bit as acurate as a dyno Jet and I have already proven that point in another thread, and when this car is ready to tune again with the new cams and clutch we will run the car on 3-4 different dyno's that are owned and operated by different people.
Not trying to start a debate or a bash fest here, LOL. Some of you guys are too much and just love to argue.

One more time.....Here is an example of a DynaPack vs DynoJet comparison that we did on a customers car a couple weeks ago. These are of the same car, same gas (91oct), same boost levels, same temperature. One was done the very next day, at the same time of day. The DynoJet was just for a couple power pulls, just to confirm and back up the JWT DynaPack numbers for you all. As you can see, the 16psi runs are almost identical numbers, but the 14psi shows the DynoJet to have a bit higher numbers.
(Note-this is not the same car as the above posted, this car has the 700BB kit on it with meth/H2o., this is Gammawolf's brothers car)

Truly not believable, but if you say so...

Head studs and gaskets are STOCK, ORIGINAL EQUIPMENT MANUFACTURER (OEM). You do not have to believe it, I do not loose any sleep at night wondering if you believe me or not. But, you and anyone else are ALWAYS welcome to come see it for yourself.

I understand where Philthy and others are coming from, I would probably be upset too if I spent a lot of extra money overbuilding every aspect of my car/motor with seemingly un-necessary components when others are spending less and acheiving comparable, or better results.
If this causes this kind of debate, I hate to see what comes from posting whatever results we get once the new clutch and cams are in. And yes, they will be from both Jim's dyno and a DynoJet.

I dont understand your point....are you thinking I am still using the RPS clutch system? If so... I am not...the RPS did not make it off the dyno. Sharif had to change it to Carbonetics Triple Disc Carbon Clutch.
edit: My statement about the RPS clutch system is a discription of what the RPS system was rated at 600rwhp....not that my car dynod at 600rwhp BTW on a DJ...I can make it over 600rwhp. The RPS system when it was on my car (on the dyno) did not make it pass 500 rwhp.
