Hey guys... I know that some guys like to hide what they are doing, it has a lot to do with competition I know. But sense I am not going to be competing... I wanted to share my setup!

TRTPerformance (Billy) is going to be doing a custom rearmount setup for me. The STS Setup alone is not sufficient and they were not willing or interested in helping us make more, so Billy is going to do a custom Fab rearmount setup with me... This is going to include custom piping both exhaust and charge to reduce the overall length of piping, reduce the amount of couplers necessary (Less places to leak from), and even change the direction in which the piping takes... The only thing that will be STS in this setup I believe is their oiling method. 4" FMIC up front... it’s gonna be nice!!

Force Fed High Performance (Brad and Scott) are going to be the heart of the setup. We are doing a custom 408 with upgraded and coated Diamond pistons... all forged as you can imagine. We are shooting for a 8.5:1 CR so I can run some good boost on pump gas. I am going to get a PT76GTS from them (I am going to hold off on the 80mm upgrade for now due to my budget) and hang that out back... shooting for 15-17PSI on pumpgas . We will see what we can do...

Fuel system still has me in my planning phase... I am considering RC 75# high res injectors so I can run them on my stock PCM, or a versafueler and some 83# injectors. Gotta make sure I get this monster enough fuel. Not sure who in the TX area is going to do my tuning yet but that will be very important too. Dual Walbro 255's in the tank.. -10AN feedline... stock feed as the return. New fuel rails and FPR. Using PSJ and MightyMouses setup as guideline.

Endstate goals: 800+ RWHP ... would like to see 900+ . Would like to join the 9sec club with my rearmount but that is gonna take some tweaking and work I think. I hope I can get all this done before I return to Iraq in December.

INPUT FROM ALL IS WELCOME!!!!

 

TRT is a good guy! Your setup sounds like its gonna be a killa!

 

you sir, will have one sick ride!

 

Shoot me a PM about tuning. I did Christians car at Billys and wouldn't mind tuning this if you were interested.

Scott

 

Jarred, shoot him a p.m. He does not rush at all; very detailed. Does it because he likes doing it, not just trying to make a quick $$.

 

Good deal!!! Keep us posted!!

 

sound like a nice combo mate!

are you going to be running stock ported manifilds or coated headers with that setup??

Chris.

 

Ya, I definetly recommend turboed stang for the tune. You wont be dissapointed.

 

we are going to port the manifolds and coat them, along with the exhaust

 

Update: Heads choice.... I was thinking hard about Darts because I need that extra strength over stock heads (as I plan on running high boost 22lbs if I can pull it off) and I dont want them to lift. I have looked at my budget and AFR's are just too much.. I think I will stay with low bbost at the begining of this build for another 8 weeks till the new Patriot Performance Castings come out with that extra thickness to keep me from lifting the heads. I dont think that build will be done for another 4-6 anyways. We will see.....

 

wow this sounds SWEET!!!!!!!! stop making me want to call billy for more stuff!!!!!!!!!!

 

You might want to think about the new Turbonetics 76MPS. Jose tested one back to back againist a 76GTS. Made virutally identical hp, but more torque due to quicker spool up. Very nice piece indeed. He is going to be trying them on some rear mount customers going full tilt with their setups this fall. Should be interesting.

For example on a viper they just finished and tested 3 different sets of 76mm units in one day.

twin 76GTS @ 22.5 psi = 1291rwhp/1284rwtq, peak torque at 4950rpms

Twin 76MPS @ 22.5psi = 1288rwhp/ 1299rwtq, peak torque at 4800rpms

So the 76MPS spooled about 150rpms quicker to the peak torque. That is very nice for a journal bearing unit.

So you may want to talk to him and discuss your options, he will know better then anyone else out there.

 

specking of turbos, TRT have you guys not thought about doing a kit using the GT42 unit??? i have heard from guys in the know that these are far superior to the older t series units. and with the ball bearings i think they would spool quicker than the t76 but make the same power.

the would the gt42 with 1.01 ar br too big??? would it spool at all?? i have seen on 2.0ltr cars these spooling up by 4K so i though with a coated exhaust system it would spool up quick!

thanks Chris.

 

Jose was the one that helped me allot in my original planning and thought process on what turbo I was going to get. I am sure it was cause he was busy, but I had called him and left him a few messages and he never returned... I am only going to chase a guy with my money for so long. LOL

He was and is very helpful... just hard to reach I guess. That is good info about the turbo... I will look into that. Hmmmm nice numbers.. any help in spooling is good for us rearmount guys.
Already thought about this... Jose, Brad (FFHP), Billy(TRTPerf) and I have also talked about this. Problem is that the GT-42 housing is a monster and will not fit under the back of the F-Bodies... It may fit under a GTO or a Vette, but not ours. That is why you havent seen a 42 on a rearmount F-Body.

 

Yes the GT42 is a monster indeed and without BB's will actually spool slower then its brother the 76GTS. Also shoot me a pm with your #, and I will have Jose call you in the morning. He is a busy man as well as Jason, and he has been out of the country for a few days but its because they are the best in the business. Its worth at least talking to him before you throw down big money

 

DAM! thats a real bitch! im sure the GT42 (with the ball bearing core) would be a real monster setup!

is the 42 a T6 housing or can you get them for a T4?????

thanks Chris.

PS can you get the T76 with a BB core???

 

The GT42 can be had in both T4 and T6. As for the 76GTS with BB, Jose has the prototypes already under testing. Also the T-netics can be had with BB core as well, but single BB.

 

Turbo... PM Sent... Good info fellas. So here is the long standing debate... what AR should I be running with a 408 but on a rearmount setup? This drags the whole thermodynamics into it again... enginjoe and engineermike and others have talked long about what the effects of cooling is to the flow of air... lets throw in the effect of AR on the turbo.

 

sounds like its gonna be a monster

 

sounds like a hefty build. BUT. IMO, u would be better off with smaller cubes. 370 MAX. 76gts is way too small, imo, for a 408. especially a high VE 408. and i think there is no way in hell u will see 17psi with a 76gts in a 408, at least not efficiently. hell, im afraid my 76gts wont be enough for 800 in my 366. remember, dont shoot for a psi goal, shoot for a power goal. an engine is just an airpump.

good luck with the build, it sound pretty mean, but imo ud be better off with smaller cubes for big hp with a rearmount turbo.
