Contour Enthusiasts Group Archives Forums General Dyno and Drag what do you guys think of this?

would you really gain 20hp at the wheels just from this swap?

Intersting to say the least. Makes me wonder what would happen on my car. I'm turning 159 hp and 157 tq right now with intake and exhaust, however a side bonus of this is the removal of the speed limiter and a bump up onthe rev limiter and i could run 19#ers.

I NEED more info on this.

me too...i need to figure out how to bypass pats...i know its possible

I want to see what happened to his A/F with him still running 17#ers with the PCM though. I have a source for a pcm , LIM and injectors. I honestly think i'ld loose torque by doing this though as my torque numbers were almost 10 lb\ft higher than the NA SVT's at SZ.

...i'm running the svt engine..and i know that theres more in it then i've been able to get out of it,and i think alot of it is the pcm...i mean the tune i have is far better than the stock pcm i was using..i just dont think the timing is right..

Well unless he has a Ford MDS (or MIDAS or ???) to reprogram the PATS that could never happen. You can not just swap out PCM's like that. (All SVT PCM's have PATS)

Also without tuning the stock setup would be rich as hell and the SVT PCM would run lean as hell comparatively using the same 17lb injectors. If he had 19lb to begin with then imagine how pig rich it ran with the stock PCM
I have no doubt from an 8 to 1 A/f to a 13 to 1 A/F will gain a lot of power. However it's not really gaining power it's getting back what you were never making.
I notice there is ZERO A/F data.


His blanket claims are pure ignorance. That is easy to see. They lack any supporting data or evidence. There is not remotely enough change between the stock code and the SVT code to warrant much of a gain. Again this is well know information.

Also I've seen bone stock regular Duratecs put down 150's many times before. His 150 numbers are nothing surprising especially considering he is quoting STD ratings. (several percent higher then SAE ratings!)

To finish. Just look at the first curve. It looks just like any dyno where the secondaries did not open or the fuel is off the deep end rich. That's not a power gain but a simple maintenance fix.

I was waiting for your reply.

So in your opinion, with the numbers i've posted now with SVT upper and TB, catback and ru3530, do you think running an SVT lower, PCM and switching to the 19# injectors would do much of anything? Like i said i was showing more torque thatn many SVT's on the dyno.

i disagree about there not being a big difference between the two pcms....when we were tuning my car the tuner brought up the rjl1 code and my xxy2 and showed me the difference in the factory tuning..it really was pretty different,the maf tuning was alot different as well...if anyone has access to the sct software with all the available contour computer data they could show you,we tried to copy all the svt pcm data and burn it on to a chip for my car,that way we could get as close as possible to factory..and then tune the car..but my pcm wouldnt accept it,fuel pump kicked on but the ignition wouldnt fire...i'll try to contact adam tomorrow,see if he can copy and paste s couple of the screens and email than to me

not trying to discredit you demon....it just seemed like a pretty big difference

damn...i've been up reading about pats four hours..even went to the patent office online,found fords pat for pats,read through some schematics etc...not much info..one site i have bookmarked said to try this,take the yellow wire and black wire from the ignition,cut them test the resistance between them,and touch the two with the corresponding resistor,it should start that way..oh well i really want to use this pcm..maybe tomorrow i'll go fish the wiring harness from the wrecked csvt..
