Some additional Trans and cooling upgrades by choice.

Final build blog details continues.
On the way to NC to bring her home to NJ after about a year in the build process.

From our August test runs decided on some additional upgrades to take on more power and better mange engine temps.

Tried 3 different thermostats hemi stock is around 210 degrees, a lot of hemi guys run 185, race ones go around 160. We even tried wide open no t stat.
Pros and cons of removing but team ended up with a custom 185 ported to allow constant flow but still functional. Either way its still hot and tight with a 6.1 in the bay

Here is a pict of the 185 after market Tstat . When engine hits 185 goes wide open. A hemi is gonna run hot Regardless. prowler bay is maybe 40% smaller than a base SRT challenger / charger.

Tranny overhaul part 3. Tranny was already upgraded earlier in the build with a custom combo of 2 kits by the perf innovations team. This time before finalizing decided to do even more by replacing the Orginal car core tranny parts for new and harden them.

Prowler transmission- I hope not to see this many more times after being upgraded. It's small a really not designed to take on 430 +HP and the torq of hemi.

Inside Trans minus torque convertor
Tq convertor was upgraded prior

Trans gear box- these are stock gears they where put back in earlier in the build to keep lower gear ratio. Way too many rpm for a 6.1 vs stock

Core tranny shaft and parts- all of which are now hardened to be stronger.
Process include a deep freeze of parts that actually changes the composition of metal and makes it harder

Nothing simple or cheap when you redesign and or upgrade the core of what makes a prowler drive the engine.

No short cuts where taken in this build we are going for the best long term durability and build quality for this custom ride!

did you do anything to the driveshaft ? I ask because I have seen pictures of one that exploded because of putting 500+ hp to it....

How about bringing the Hemi to Nova Scotia next August for our Prowler Event... looking like 20-30 cars..

Drive shaft can handle it. It was shorten strengthened, calibrated and rebuilt to accept the hemi motor and connect to the Trans. Key is it must be perfectly placed. It keeps Turning and at much higher speeds than a V6 it's the tranny and tq convertor that must take the load.
No matter what anyone does or says it is the pinch point limiting factor of any prowler build unless you replace it with like a zo6 rear end etc and that's big buck. Any motor you can put in will spin but if the Trans doesn't take it your toast.

Here's what a standard hemi Trans looks like
Big difference and the power guys even upgrade the bolt on

We did the best we can with what was given still have to be careful.
Remember stock hemis have bolt on Trans that means it takes the shock directly from the motor so the prowler in the rear has 2 negatives small and seperate. The alluminum shaft will keep spinning

Heres a snap shot muffler removed

I will have to watch it and be careful! No more slam the gas to the floor wide open throttle through every gear like I did before on the track with the V6. I may end up sitting on a bed of tranny parts.
Sharing the truth no smoke and mirrors.

On the hemi cat we are running 3 different computers
(Hemi, stock prowler and Trans) with that its key to keep an eye on the cars peformance temps, codes etc.

Many new cars have a lot of this stuff built right into the dash.

To keep this under control
Ended up buying a cool monitor called scan gage 2.

It's like many of the standard code readers on the market but very portable and easy to use.

Its connected to the ecu plug that sits below the dash on the driver side.
Reads and displays and can clear codes
Show HP, MPG, 1/4 mile, Rpms, speed, engine temps, voltage, air temps, Engine timing, trip computer and much more.

Here goes a demo video a guy did on YouTube http://www.youtube.com/watch?v=ngW9qGYOzhg

Here's more on
3 computers that we are monitoring
1. Stock prowler computer - controls, dash basic prowler things, a/c switches, lights, tie to trans, ignition etc

2. Manual hemi computer- controls motor, and all of the core engine related parts, since its a manual doesn't look for tranny codes to run

Was hoping for better audio sound with from the Gopro, still didnt work so well a bit too much wind blowing but at least can hear the engine in the beginning from a stand still. at least i left the Hard top off this time!! Ha Ha
Was just happy to be driving it. That Radar looks kind of bad too but there is alot of cops down here in NC. I saw one with a black SS camaro, chargers etc. and just a bunch of blue lights that pop up on folks. Many unmarked.
I was just really cruising the highways testing again about 100 miles.

Looks like a mean face with a black shaker hat
Ha ha

Different side view

Everytime I see and get back in the car I stare and take a hard look for awhile. It's very different.
This picture is very in your face it always amazes me how they got this hood to grade up almost 4 inches from stock out of hand formed alluminum to match the shaker.

Does anyone remember these Humble beginings ? I sure do, a reflection point sure have come a long way

I see it more as the windshield/headrests are eyes, the shaker as a nose and the grill is the mouth. Looks like a guy smiling.

Actually it looks like you Trey lol. OMG!

The stroker is proven you can keep pretty much everything the same but will tell you nothing is cheap.
Low production+ limited space+ most people are low
Mile crusiers+ the rear mounted tranny = limited options
And high costs no matter what. Even the stroker is not cheap.
Low to mid teens last time I checked.

You have to get into the internals of the V6 to get more thus a bore and stroke can work but must be done right. Stroker is find of a sleeper, but there has been a number of people that have done it! Deans 5.0 was an engineering feat and far from easy if you study that hillborn scope and custom intergrated throttle body it is very amazing that he was able to pull that off.

By the time I looked at the cost to HP / performance benfit of the 4.2 rolled the dice and went 6.1. 4.2-4.3 Stroker is a much more reliable and simpler process because your basically going inside the engine, upgrading and increasing displacement on the existing design. But with that your still limited to the core. The Chrysler engineers did a pretty good jobs maxing out the potiential of the 3.5 V6.

Here is a nice post on the westech stroker.
From one of the early pioneers Marty.

http://www.prowleronline.com/ubb/Forum9/HTML/002244.html

Marty and laddie are the in house experts on this one you can also call westech they know prowlers well and also built Mikes worlds fastest 5.0.
4.2 or 4.3 would be more of a real world option. You can talk to eds cat or terry on 5.0 but you cannot get one anymore. Turbos Only 2 done, superchargers Paxton started early but stopped. Work was required to get it to work but did deliver boost. Nitrous does nothing for around the town or normal cruising.

I'm staying the hemi route as with everything its risky but we will get it right with well over 430hp and 425 ft lbs of torque in a 2900 lb car.

Just for a perspective that is 2013 porshe 911 levels of power delivery. There's is a better refined design and engineering but cost more than 100k. Same SRT motor is in a 4200 lb challenger. A grand sport vette weighs 3208 lbs, is around same power and cost much more than a hemi prowler complete. We are talking supercar level power to weight ratios in a exisiting car we all love and turns heads more so I said why not!

But as you can see nothing comes easy your changing the entire DNA of the car and its a custom build. Doing a 5.7 or 6.1 you still have to do all of the same type of work.

I really think if Chrysler could have pulled off a strong V8 into the Prowler design back in the late 90's they would have!

The rear transmission used at the time could not handle the torque generated by the V8 and they did not want to spend money on retooling everything.

CJ thanks your soooo right tranny is still the major pinch point 15 years later and for all of the major go fast high hp builds to date.

We have 2-3 custom kits, extra clutches and even hardened and replaced much of thr core internals but no matter what we are still limited to the space, size and overall design. We have had it out many different times to get to max out its peak potiential. Here is some behind the scenes looks.

In reality for me there won't be anymore
Slam it to the floor wide open throttle through the gears off the line especially 3rd to 4th like I used to.

With the shock of 420 ftlbs of torque through the drive shaft

to this tranny Wide open throttle just may end up sitting on a bunch of blown clutches and a shot Trans.

In normal driving I'm typically less than 1/2 throttle with the new electronic throttle these days. We had to change the entire pedal system also from stock cable based to electronic. With The newer hemi engine computer every thing is electronic.

With all of this going on Have had to learn to drive differently. Auto is ok for basic crusing. but you have to stay in auto shift when working it hard on the road since the power band and shift points are so different. Also SRTs run bolt on 5 speed Trans we are 4 in the rear.

I give you example know when you on the highway going maybe 50-60 and you want to pass in 4th? you and the computer may drop the prowler into third. Or if you slam it hard when crusing and the car down shifts?

That happened to me on 6.1 the prowler trans computer in auto did the same thing like a V6 and down shifted from 4 or 3 the hemi had so much more power and at a higher RPM that the engine roared and jumped, I had to hold her back. A bit scary but fun!

To help better explain watch the attached test video.
go to .45 min. Here i start the car from a start with less than 1/2 a throttle. listen to the motor rev up really high in gear. very different than before.

Very different but a ton of fun on the run!

Looks like the 5.0 stroker that inspired and started my whole exploration for a fast prowler is back!!
