Whippled 405 Jeep Srt8

143 posts in this topic

Update:

 

Finally had some time off again and played with the Jeep.  Installed the AC condenser/transmission cooler and the power steering cooler (hidden under the bumper in this picture) and the cooler for the supercharger coolant system.

Installed the front brace and support arms and the hood latch.

Used my airlift vacuum fill for the coolant system.

Filled all the fluids that hadn’t already been filled and then leak checked the fuel system.  Then started the thing for the first time.  Video of it running to come.

That does sound good!  I guess you're going to make CF7 then?

 

That would be kick ass.

 

Sounds great Kevin. We are leaving Omaha next Thursday at 6 am, text me if you want to roll with us. AJ will be in Bowling Green, you can run it at the track and have immediate tuning feedback. :)   I probably shouldn't speak for AJ but I just did lol

Yeah, I don't know if we will make it this year.  If we did, it would be to watch and learn.  The Jeep will be eased back onto the road with small steps and goals.  You've seen how methodical we were on the build, it will be the same for tuning and running.  I'm not the kind of guy who will test it's limits the first time out.

 

I installed the first revision to the base tune today and got a better video of the Jeep idling.  We are still in the heat cycle phase for the engine and will load the engine next as soon as I get a thumbs up from my tuner and my engine builder.  No leaks so far.  Fuel system is solid.  No oil leaks.  No transmission fluid leaks.  Coolant system is still burping which is to be expected and playing nicely.  No error codes of any kind which is absolutely afu(kingmazing!  Knock on wood.  We haven't turned the steering wheel yet, which will be a big step.  That will load the power steering pump and pressurize the lines and that entire system has been reconfigured so wish me luck on that.

 

It's starting to sound a little better to me.  It doesn't have a lot of lope but this is a supercharged engine designed around low rpm torque and not high rpm horsepower.  Give and take, right?

 

Deep!  Holy crap is the sound deep!  Sounds louder than it probably is due to being in the garage while running but the deepness is such that you feel it in your chest.  So far so good.

I have changed a few things around and I'm way behind on updates.  The Jeep is currently at MMX getting the tuning finalized.  The conqueror transmission was upgraded to a super pro.  The cat-back exhaust is being redone now.  The Corsa was good up to 700hp and then became the restriction.  I should have known better, I made a mistake overlooking that.  MMX will be building me a custom 3" exhaust from the Kooks back.  I had them put in DSS axle shafts and install my front wavetrac while it was there as well.  Waiting on it to get finished up there before I work on a couple other things I had planned for it.

Good news is it's running well.  I post some more up when I get it back or have more to report.

Interesting that MMX feels the Corsa is an issue. We've dynoed Jeeps well above the 700rwhp level with the corsa without issues. Its a hit vs a cutout but a cutout is a lot cheaper then a full exhaust fab....

 

Glad to hear its running well. Will we see you at Maple Grove?

I've seen 1200 rwhp made thru a Corsa so that is surprising, unless it's something specific to the jeep cat back.

What size is the Corsa on those exhausts?

The Jeep Corsa is a 2.5" but it necks down pretty good at the inlet of the resonators even more.  The Kooks are 3" outlets with no cats.  When the 2.75" pulley was installed in place of the 3.25", the Jeep wasn't responding right.  I think they fought it for a couple days on the dyno and it wasn't until they disconnected the cat back that it finally behaved the way they expected.

Hmmm....that explains it then. Corsa LX / LC car exhaust for a R/T is 2 1/2",  SRT8 is 2 3/4".
