You beat me to it, was going to ask how much LTs and and O/R mid-pipe drops the boost. I would have guessed more than 1 psi.:shrug:

I don't know if its an exact number but its around there depends, could be 1 or 2

@birdoc or you can add long tubes which will likely lower you boost 1 psi making it even safer and you can run upper and 10 lower :burnout:
I dropped my boost slightly less than 1 lbs with the addition of my AR 1 7/8 LT's.
I should help decrease stress on the 5.8 for the long haul and is something great to consider if you increase your boost.
Outside of that they sound awesome :beer: I took another forum member and his wife for a ride this past weekend. Afterwards his wife said he needed to get LT's! LOL!
I currently have a 2.4 upper and have been kicking around the idea of throwing on a lower. I know a few people on here run 10% OD's with a 2.4 upper without a problem on 93. I have been told conflicting things about a 2.4/15% setup and just curious if anyone already is doing this.
Does anyone run a 2.4 Upper and a 15% OD setup?
I wouldn't immediately write off the possibly of running a 15% plus the 2.4 first off I'd try to find a set of 2 inch LTs I'm not sure if anyone makes them yet but id do them if they do. Should drop the boost at least 1lb. Next you could do a couple things to help as well. Run higher than 93 octane (100oct at least like you said you have been) Than you could always add methanol injection to battle the heat because it flat out works. Last of all you could port the blower to increase efficiency and lower boost. I think it can be done with the correct supporting mods.
Ya I ordered an offroad X pipe and a 15% OD. This car has never seen anything less than 100octane since I picked it up from the dealer June 12th. It also only has 977 miles on it since I never have that much time to drive it hahaha. Wrenching on them is half the fun anyhow.
In the future if I get bored I may pull the blower for porting. A friend of mine has a machine shop and he does nice work.
It'll probably be a good month before I have time to fly back to GA and install the parts and get it retuned. I'll post up #'s and info as soon as it gets finished though :beer:
Do you already have a 2.4 on the car?
Just for my own clarification; The blower is becoming less efficient past 18K a.k.a. creating more heat per "horsepower". For a lack of a better term?
In your opinion you would only run a stock upper to stay within the efficiency window throughout the entire rpm range?
I would not run a 15%+2.4 with only an off road x and 100 octane. You need at LEAST two of the following 3: headers, meth, ported blower.
Yes based on the calculated numbers to keep the blower speed within the TVS compressor map sweet spot that would be correct. That why Ford chose to go with the 2.7 as the smallest pulley they could on the 2013 TVS blower. This would be most important especially for open track use.
That said if you wanted to "push the limits" for street or occasional drag race use and still maintain some margin of safety and relatively cool blower inlet temps then the 10% lower with the stock upper would yield the max blower RPMs and least belt slippage for the TVS. Like I said earlier to suggest a smaller 2.4 upper along with a 10% lower is simply bad advice for many reasons.
Can it be done? sure but it comes with a price. Not only the added cost $$ of another pulley but at the cost of higher blower inlet temps and increased belt slippage, both of which equal lost HP when you want it the most....repeatable power while under a load shifting through the gears going down the track will be lost.
Just trying to educate here with the facts so you guys can make an informed intelligent decision before you decide what direction to go when choosing the correct combination of parts for your car. At least armed with accurate data one can then make their own decision how far they want to take things past the recommended limits and weigh the risk vs reward they are willing to take. Remember Dyno numbers don't tell the whole story about power but they do help foster sales and chest pumping....
Longtubes possibly down the road and a ported blower whenever I have time and get off my ass to yank the stocker off haha. To many horror stories with Meth so I'll pass on that. We'll see how it takes the 15% and 2.4 first. If its not looking good the stock upper will be going back on :beer:
IATs are gonna sky rocket causing detonation without at least two of the three. Save the 15 until you are ready to address the heat it will produce.
700whp is not enough for u ? are u planning to race with somebody?
What he said ^ like I said. Address the heat issues caused by higher boost and you will push the efficiency range higher and higher.
Put the 2.4 + 15% and it will pull so much timing it will make less power than before. Trying that setup without supporting cooling mods is like asking to pop your motor.
Hmmm maybe ill have to machine it down to a 10% then. I know that combo works just fine with no extra cooling mods on 93.
