GT350 will destroy everything!

[Voodooo]

I was read in a press release that the R had a hotter tune. Never have seen anything to prove it but really never questioned it either. As far as the other 3 I haven't been able to find anything that says the tunes are different. The cams being different I don't believe at all.

Exactly. I've been to Watson racing many times and according to them and the dyno graphs I've seen from them on their dyno all the GT350's (20+) have dynoed within 5-8hp. That's not enough to prove anything. The only difference I see between the base, track/tech/R are suspension programs and speedo calibrations on the R. And that's all in the BMC NOT the pcm.

There has never been a press release from Ford stating as such. Pericak did state due to a lack of resonators that the R breathed slightly better which results in a couple more horsepower but that Ford didn't bother to recertify the combination.

Different load doesn't mean the cars make different power. Could be the limp mode settings of the differential pump etc

I understand that. But he said the engine tunes and cams are different in the base model.

Wasn't necessarily from Ford and I wasn't saying it was. It was before the cars were out and while it did have allot of "From Ford" type info, I really don't remember the details. Just remember the article said in roughly these words "The GT350R has a hotter tune"... I really didn't think anything of it as i wouldn't be surprised if it did.

The only thing I'll say is if the GT350R has a "hotter tune" why is it not rated with a higher HP then the regular GT350?

Well by hotter if you mean 4hp well maybe.

MotorTrend dyno'd both versions. The fact that the R has a shorter final drive should make up the 4hp.

It doesn't have a hotter tune.

If any car in that MotorTrend dyno comparssion had a "hot tune" it was the Z28

Hotter tunes don't have to be focused on HP, even though that's the easily-understood measure for things like drag racing and bragging rights on the forums.

For a road course car, midrange torque would probably be more valuable.

I understand that. But he said the engine tunes and cams are different in the base model.

Whether auto correct or mis type. the gt350 cams in ALL motors are the same. PCM tunes and calibrations are different on the 2016 models changing reaction time to fuel to tps, yaw, etc. This is how each car runs, acts and handles different from model to model.

Fyi a dyno cannot tell you this info!!!!!!!! This is software based variables that helps these cars transfer weight(speed and acceleration), fuel to air to tps(throttle position sensor) which creates fuel and power rollover control(how abrupt power curve comes on or doesn't). Lots of variables that help these cars go fast and handle great. Throw in yaw(interaction of traction control, abs and other factors) then the magneride(controls some yaw and weight transfer, traction). All these factors weigh in overall on these cars. If you put 1000hp out to the wheels but you have no traction or control what happens? Death machine? Probably worse than no controls at all.

All I am saying is that I have seen 11 gt350 PCM programs loaded on to a computer at an engineering event that some Ford and related vendors showed some software on how and where parameters were different, how to change them, measurements as load, static and dynamics, etc. Of all the true base had the least amount of parameters than the other models. That is why the true base is the best gt350 to modify in my opinion.

On the cams, I heard there are some current manufactured cams out there that help the 5.2 develop some more torque and HP. Thought they might have been the cams used in the aluminator motor.

Just to be clear, I'm not saying it does or trying to put mis-info out, just replying to what other have said and relaying something I once read. I have no idea if it's true or not.

I understand all of this and I'm not disputing it, maybe I misunderstood your earlier post, but I thought you said the engine tune and cams were different. Sorry.
As far as modifications go, I agree the base would be the best choice. To bad they don't have the coolers though. As I said before, if I had a base I'd do the same mods that I have done and add DSSV dampers and dump a lot of weight from the car.
I still plan on building a 700hp NA Voodoo in the near future, and I hope to find a 3160 sequential tremec. I'd rather not go to another 6060 trans.
I've contacted Pftizner and Quaife and still haven't heard back yet.
If someone is grinding cams for the voodoo I'd be very interested in knowing about them.

thats true,the CRAPMARO z28 had the same hp as the GT350 R.as you know,Garbage Motors always send out RINGER cars to be tested.:lol:
