Has anyone "upgraded" from a regular GT radiator to a PP or GT350 radiator? The PP and GT350 are the same which have about a 1/2" thicker core and hold about 0.6 quart more fluid than the GT. Just wondering if it would be worth it. I know Mishimoto makes one but I believe it is too thick...

I have a yellow 2015 twin turbo Mustang GT convertible that is fully loaded with the 401A interior package. The sticker price on the car was $48,690. It has 5600 total miles on it with 1600 miles on the new Aluminator short block, built transmission and 600 miles on the upgraded turbos and...

This was last night in Thunder Valley at the Street Car Takeover. I was car 66 in the right lane

Who all has used this, how did you like it? I don't really want to cut into my factory wiring harness, anything else out there?

How are you guys launching with your 6R80 Hellion cars? 1. What tires - MT 305/45/17 ET Street R 2. What converter - 3B 3. Do you use a 2-step (if so what launch rpm) - Yes 2900 4. How long are you on the 2-step 1.5-2 seconds 5. What is your best 60' - 1.54 (once :( normally 1.6x range) Mine...

I received my car back from TSS after the new build (mods are in my sig) with the Hellion Twin kit and the 55mm turbos. It made 910whp/927tq on 19lbs with E-85 on a Mustang Dyno (not sure what that would be on a Dynojet). I am waiting for the dyno video, I will add it as soon as I get it from...

Has anyone made over 900whp with the S550 Hellion twin turbo system using their 55mm turbos besides Sheldon Lewis and Hellion?

I went to the track last night it was around 73 degrees and the DA was around 1800. I was at full weight with 3/4 tank of gas, and on 20" wheels. I made the first pass and lifted after the 1/8 just to check things out, then ran it out the back door on the second pass, they politely asked me to...

Turbos and intercooler came in last week, piping came in today, and now is on its way to be coated! I also have ID 1000's, Eboost2, AIS water/meth kit and KB boost a pump waiting in my parts bin.

2015 Mustang GT resonator delete X-Pipe from Lethal Performance. I finally received my new Magnaflow exhaust so this is off the car and ready to ship, it might have 1100 miles on it. $250 shipped

There is little to no base from the subwoofer mounted in the trunk (I have a convertible). Has anyone just changed out the subwoofer? I found a Rockford Fosgate P3SD2-8 300 Watt 8" Dual 2 Ohm shallow mount truck subwoofer that I think will fit. I just don't know if it will be any better or if...

Does anyone have a 20x10 +40mm with a 305/35/20 or larger tire on the back with Eibach Pro lowering springs? Do you have any pics, do they rub at all anywhere? Thanks in advance.

I weighed my car today, specs are in my sig, half a tank of gas, and a baby seat without driver.

Has anyone broken a half shaft with an automatic yet? If so what mods/tires/HP/TQ I have a Circle D converter on the way. I am eventually going to buy some, but I was wondering how much time I have until I "need" them?

My local track opened today it was 67ish degrees and the DA was around 700ish. Dyno sheet of car and time slips below. Mods are in my sig. Full weight convertible, I haven't weighed it yet but I would guess 4000+lbs

I am looking at another set of wheels for my car, I will have to wait for the fronts to get back in stock before I can sell these. They are factory 20x9 with either 2 or 4 stock tires. I put drag radials on the back so I might keep the 2 I took off the back for the front of the other wheels...

Car is really dirty, It's been snowing so I haven't been able to wash it.

Got back from the dyno, a little dissapointing, I only gained 35rwhp and 24tq. Previous best with stock tune was 363.46/352.39 this time 397.85/376.17. Here is an overlay of my previous dyno but they used the one of the SCT canned tune runs. The temp was 47 at the last dyno session, it was 50...
