1) Correct, you will see a drop in fuel economy if your foot is in the gas as the added PSI will require added fuel to keep the proper Air/Fuel mixture. BUT your supercharger also has a bypass valve which allows you to drive around without any boost pressure at all, just as your stock supercharger does currently. So ultimately you wont see the gas mileage drop until you put your foot in it

here while back i ran 10.90 with 740rwhp then drove home getting just over 20mpg.but you get in the throttle just a little that fuel gauge shows it real quick.
the pulley tune route will give a nice boost. then you can decide to go big or stay conservative

Re: Let the modding begin!

Post by Corepuncher on 7/28/2011, 12:12 am

I have decided against an upgraded supercharger and to just go with pulley + tune. Mainly because it's my "Every day driving" car and secondly because of cost. Also, it's possible I would upgrade to a 2014+ Shelby at some point, but how knows.

So here is my Mod list (in no particular order)

Pulley and Tune + Plug kit
Larger throttle body
Dual fan heat exchanger
Rear control arms
MGW Shifter
Aluminum driveshaft to drop weight and rotational mass.
Remove cats...change mufflers??

I have a few questions about all this.

For control arms, are we just talking rear? Then, are we wanting to replace both upper and lower?

For exhaust...my goal is to gain hp and decrease weight by removing the cats...what do I get in it's place...just an offroad pipe? Then for mufflers...are the stock ones considered "high flow" ?

Now...I need to decided the order of all this. I am leaning towards tune/pulley kit up front. But I do notice (in this 107 degree weather) my car runs REALLY hot when I get the SC whining...so heat exchanger is right up there....and control arms would be next.

Then, I'd like to narrow it down to 2 places for tune...Lethal Performance and ...

Finally, a really dumb and potentially lazy question (as I'm not dressed and am not gonna go outside at this late hour)...is this "Heat Exchanger" simply the Radiator for this car...or are there two cooling deallys?

I just got done chroming out my interior handles/knobs. Sweet!

1) Pulley and tune (Lethal uses Jon Lund tunes, so good choice) will def be a worthwhile mod.

2) Heat Exchanger will definitely be a benefit in this heat and keep temps cool.

3) An adjustable rear upper control arm will help eliminate wheel hop...and might also be a good idea to upgrade to fixed rear non-adjustable lowers at the same time to help plant the tires and keep the car straight during hard acceleration.

4) If you get an Off-Road midpipe it will eliminate the catalytic converters BUT it will be LOUD with stock mufflers and you might not like the sound. I wouldnt be too worried about "Saving weight" as that is easily cured with HP. If your concerned about weight, you might keep the midpipe stock and go with the Off-Road Roush rear exhaust which elminates the rear mufflers and supposedly sounds pretty darn good

Here is a quick clip of just the Lethal Off-Road X midpipe (no cats) and stock mufflers. Notice the popping, you will have a lot of that on deceleration. I did not like it so I installed resonators in the exhaust to tone it down and smooth out the sound.

sounds like we may have to make a club run down to Norman in the next couple of months...

leave the orange at home!

I've never really been a big fan of the aluminum driveshaft unless you are looking to scrounge every last pound you can. Rotational mass is good, but when you up the boost you'll forget about that 30 pounds you saved on the driveshaft.

When decided on a place to tune, it's really all up to you whether you want to go the remote tune route or go in-person on a dyno. Remote tuning is definitely cheaper, since no dyno is required, but some of our members have had issues with remote tuning (David), while others have had no issues (Jarrod).

Do you have a tuner already purchased? That make a big difference on where you tune as well. Since the car is so new, I am assuming you have not. I love my Diablosport, but the lack of local tuning has me looking at two options - learn to tune it myself, or get an SCT. Several SCT tuners in the state, not very many Diablosport tuners in the region...

Jarrod, I inquired about the lethal tune but you only get 1 I guess? Is this an "all around" tune? Like some places give you "every day" and "performance and "Race" tunes altogether.

Pulley,CAI,Reisch Thermostat,Heat exchanger,Plugs and a DYNO tune.Would be the first step IMHO.Sorry Jarrod,I'm just not a big fan of box tunes.Seen too many variations in files from the cars we have done with the exact same mods.JLT is my choice in intakes and Metco is my choice for pulleys and suspension.Don't forget a auxiliary idler.You will be pleasantly surprised at the difference this all makes.I would do upper and lower control arms with the instant center brackets,as the instant center on these cars is way too far forward and it passes the front bumper if lowered.Hope that helps in your endeavor,have fun.

Thanks cobradoc. I am not sold on tunes yet...where would you suggest getting a tune from in Oklahoma? Is there a place around the OKC or TUL area that will work with your car and find the best tune?

What does the Reisch Thermostat do over stock?

If you want to bring the car to Tulsa some time, Archangel here in the no-man's land between Owasso and Tulsa is a great place. If you want to stay in OKC, I would go to Abel Racing in Midwest City

Re: Let the modding begin!

No worries Rick, opinions always differ.

But to your point I absolutely do agree that you are right. A dyno tune is always the #1 way to get the most out of your setup, but finding a tuner that understands ALL facits of these newer GT500s and the larger/complex computer can be difficult (much different than the 2007-2010). Lund seems to have figured it out and his results have been phenominal

Ryan if you are looking for a local tuner, talk to Kurtis at Archangel about your setup and he can get you squared away. He is local and can make any and all adjustments needed to make sure the car is running properly.

The Race-performance-everyday-etc tunes are a marketing gimik in my opinion. Octane, current mods, and Enthenol/non-ethenol is what you need to focus on (91 octane tune and if you use 100% gas pumps or pumps that have ethenol) those key factors will effect the way your tuner tunes the car.

The Lower Thermostat allows coolant to circulate at a lower operating temperature. Helps cool things down.

Although there are some arguements that state that it is not good for the oil in the winter time as the car has difficulty getting up to operating temperatures as it is and oil viscosity can be effected. I myself think the benifits outweigh the cons and I do run one.

Re: Let the modding begin!

Post by Corepuncher on 9/15/2011, 6:17 pm

Ok...I"m selling some stuff on eBay, and hope to have about 3000 dollars to spend on further mods.

Here is what I have done so far:Air Filters and Resonator Eliminator, Roush tank, C&R Heat Exchanger, 170 deg thermostat. Also just got my Escort 9500 ix rad/laser detector :-)...that was a chunka change as well.

Now, the question becomes how best to use the rest of my dry powder.

That used 2.3 L TVS would use up about 2000-2350, depending on how much he might come down.

Then there is the control arm issue, pulley/tune if I choose not to do TVS. MGW shifter which I am really looking forward to. I've also heard panhard bar, oil separator, could even mess with exhaust but I kinda like it for now. I also need to fix my chin splitter...if I go carbon fiber it would be a pretty penny!

So if I went pulley/tune kit, I could get a lot more other stuff done, compared to the TVS blower which would use up a lot. But if I got the new blower, it's even more critical that I MUST spend even more money on getting that power to the ground. New tires? UGH!!!!!!

This is a fun problem to have LOL :-)

So...if you had my current setup and $3000...what would YOU spend it on?

I would love to have your problems! All of the above choices are a personal one.

The Blower is a great mod and will add more power than you will ever need.

But the pulley and tune might increase the fun factor enough to tied you over, all the while letting you spend on the suspension and other goodies. But when and if you decide on the blower you just wasted the $700 spend on the pulley and tune.

Eventually you will want more power, which you could go with a lower pulley to try and "tied you over again", BUT its a sure thing you will want more than that after you get used to it. The blower in innevitable.....

Good luck sir

I'll have to find out for sure if his 2.3l TVS will fit fine on our 2011s...I assume so since nothing really changed much from 2010? I"m gonna offer him 2000 and see what he says.

I was unaware of the TVS on the '11s requiring any fuel upgrades if staying in recommended duty cycle ranges of the pumps and injectors.

Here is an article of a TVS Swap on an '11 that Justin Starkey at VMP did, they claim the injectors and pumps were sufficient even at 654rwhp.

http://www.teamshelby.com/forums/index.php?/topic/63475-2011-gt500-146rwhp167rwtq-with-vmp-tvs-supercharger/

I also didnt know that the '11s had the capability to adjust the alternator voltage (very cool!).

Here is a quote from VMP

" The 11s actually have a feature that is very neat, they can increase alternator voltage based on fuel pump flow rate. With an extra .3v-.5v kick, the stock fuel pumps had plenty of capacity. "

Van says:

"FYI. With a TVS on a 2011 you do not need fuel system upgrades. We can get the car to hook better with some suspension mods. You'll need an EVAP relo kit for the TVS on a 2011. No big deal. $10."

Is that the Night Rider mod? :-)

So Van is trying to talk me into getting the TVS....of course! I'm gonna have to find a way to pull a rabbit out of my hat. If I didn't have to buy that 3100 dollar storm shelter I could get all this for sure...but hey, when you live in the fricken F5 bullseye of planet Earth, you better have a shelter!

You could always go with a 10% or 15% lower pulley next to add more boost, then port the stock blower for even more. There are lots of less expensive options!!

I am not familiar with porting the stock blower. What does that entail? Also some are replacing throttle bodies...would that be advisable as well (kinda expensive!)

2 places I recommend...either Posi or Stieg

Posi website...you can either go directly through them or go with a vendor
http://www.posiperformance.com/gt500-race-port

VMP is a vendor who sells the posi ported stock blower
http://www.vmptuning.com/store/index.php?p=product&id=351&parent=103


Here is Stiegmeier's website

http://www.stiegemeier.com/gt500.html


Posi ports are a little more aggressive I hear. You could also check with Van at Revan Racing or Kurtis at Archangel to see if there is somewhere else they would recommend.

Its an overdrive balancer pulley, typically most just do the upper pulley...so the kits are tailored to the market. The 10% lower should add another 3lbs of boost or so...there is also a 15% available

http://www.revanracing.com/products/innovators-west-2011-2012-shelby-gt500-10-overdrive-balancer.html


Same pulley offered by Lethal performance
