Thanks to this site and all the friendly and helpfull people here; Mr Hemi gave me permission to post pic's and details of a complete build for a supercharged Hemi engine. We will take you through the step by step process. From pulling the motor, to the final tuning. Starting tomorrow morning at 9 am, we will be tearing into the truck. We will give you a day by day post and pic's of the truck in progress. Currently, there are 11 other on going project vehicles that are being worked on. Somedays my truck will have to take a back burner. I want to take the time right now, to thank the many people on this site, that have answered all my many questions and make this happen.

We have some part throttle tuning to do yet. After that, we will get you some track numbers. With the 3500 stall converter, we would see less than desireable dyno numbers. We just witnessed a full blown 454, with 699 hp, from an engine dyno, only post 500 hp from a chassie dyno with a 4000 stall. Dyno's are a great tuning aid, but are not real time hp/wt ratio numbers. At the track, the true hp numbers show in the et slip. Last years race weight was at 5170lbs. This year I should be a tad lighter. Once we get the new race weight and an et slip, we can then convert how much horsepower is going to the ground. That's when the next step starts. We can then start to dial in the truck with those same et numbers. That's when we start looking into chassie mod's... Traction issues, gears, tires, front to rear weight transfer, 60 ft times and so on and so on. Once the truck has been dialed in to it's best, you just live with the calculated hp numbers that you have. Does this make sense?

I'd like to add these truck sence load and change the tune accordingly. So, your street tune will show lean on the dyno, and your dyno tune will show rich on the street.

I'm not sure yet how much the smt6 is affected by this but, it get's it's info from the stock pcm and I don't think it will act any different

I see. It all makes sense!

I wonder how the four wheel dyno setup will be. I heard that they have tension adjustment for the difference in wheel speed.

I hope to see you guys pull 1.7 - 1.5 60ft times

Yep....have to agree, the track tells it all....!!!!! Can't wait to see the slips....!!!!

No worries Denny... Just was hoping to see some great #s before (hopefully not) any other unfortunate melt downs... Thats all...

I wish you guys nothing but the best..

The track times will always be the ticket for showing exact power. However, not many folks come back and say they had a perfect night, nothing could have been better. LOL. So much human/weather error to be had. Tire spin, head wind, tail wind, heat, humidity, shift points, 60' time, didn't stall up enough, incorrect tire size...seems there is always an excuse on why the ET's aren't where they should and then the claims are made on what you WOULD have run if those errors wouldn't have occured and then you end up with a 1/2 second faster ET than what your paper shows.

That 3500 stall will skew things on the dyno. Mine stalls around 2600 to 2800 and I always dyno'd 30hp less that my friends with the same config (minus the converter) at the dyno days. My converter is probably a little loose too.

Yep...I'm going tp Moroso on Aug 6th and hope to get a couple of runs in...I am sure I will not see a 13.88 that the SC Tuner gave me...low 14's on spray is probably more like it...have the FJO Minicontroller ordered and that should help the 60 foot time a li'l..????

I'm not worried about having the fastest truck on the planet, Parish has that covered. It'll run what it runs. From the state of other projects out there. We are ahead of the game just having it running. Will we be happy with the first outing to the track?? Maybe, I hope so. But you can never be sure until you do it. The 1200 blower we have now is at it's limit RPM wise and supports 680hp. Spinning it any faster will just make it ineffiecient. As long as the trans holds up, then it can get a bigger blower. The original goal was to make 800hp. The 1500 novi can support 830. One step at a time.

hemi2nv have you thought about putting a 727 or 518 in that truck? You know 1 cut starter ring off flex plate. 2 bolt trans to engine 3 bolt TC to flex plate and off you go.

You forgot about #4. Disconnect the TCM from the PCM. LOL We are trying to keep the truck as close to stock form as possible. The 727/518 would be the easy way to do it. We are confident by changing out the TC will solve the issues at hand. We should now soon.

I forgot about the martin sain conveter Jerry had in it last yr. So this one makes 3.

Trans # 2 had a 3600 stall converter that created to much heat. It broke down the fluid and, of course we were testing and abusing it.
The trans temps were 120+ C several times. You could drive down the road and the temps just kept climbing. The 3600 stall was loads of fun, but it cooked the trans. It didn't go into limp mode like the first one, but we knew there was trouble cause it stopped looking for overdrive.

Once you get the tranny beefed up you're going to start twisting axles and ring gears, lol. Are you using the stock driveshaft still? Steel or aluminum? If so I bet those u-joints are crying for mommy

I'm glad that you're beating the hell out of the stock components so we can see how much they will take before giving it up. I can't imagine what will happen when you crank up the boost.
