I have the Hellion 62s on my car. Honestly, if the 55s make more power down low, that would definitely push me towards the 62s. I run 305 NT05TRs and have no traction, even with my boost controller set to the lowest (Westgate, 7.5lbs) boost. The 62s pull crazy hard up top. Other than Viking...

Mine is a turbo car but when my trans was stock I began having very inconsistent shifts while under power at the track. It would sporadically pause/delay between the shifts, which got progressively worse. I dealt with this for 3 separate trips to the track (approximately 15 passes) until the...

Had my Hellion kit on my car since fall of 2016. Fit perfectly, great customer service and car hauls ass. Also never had any issues with high inlet air temps (on road or track)and I'm in Florida. It's an outstanding kit and I'm glad I got it.

Hey all, I don't know if it's been talked about yet because the search function didn't work for me, but I wanted to share my experience with the Dragy performance meter. I was going to purchase a more expensive peformance meter in the next month or so but learned of the Dragy unit on the Audi...

Sai also tuned my twin turbo car. I wanted a conservative tune and can't say enough about how solid it has been. Extremely conservative timing and it makes a lot more power than I am able to use right now. I've been running on it for over a year with zero issues. Very laid back, patient guy...

This is my first turbo car. My tuner and several other experienced turbo guys recommended the boost leash, so that's what I got. Very simple to use and works flawlessly. I like the scramble feature on the street (kind of set up like a nitrous switchl) because high boost won't hook so I can...

I've had 3 cars with positive displacement supercharger (09 CTS-V, 2007 Mustang GT I put a Whipple/Kooks longtubes on and a 13 GT500). All of them were pullied/modded and all were reliable, fun to drive and fast. That being said, NOTHING I have driven pulls like the Hellion kit I put on my...

Another vote for the magnaflows...i have the Hellion twin turbo kit and initially had the same flowmaster x pipe/axle back setup that I had on it before turbos. Sounded hideous, like a tractor with tons of rattle from the mufflers. Learned that you want a straight through style muffler on turbo...

Sai was running it on the dyno so I know it was done correctly. I'm running NT05Rs (305/19, 18 lbs.) and I discovered on my last couple of passes that they worked much better with a long, smoky burnout, which I wasn't doing earlier. I ran out of time to try to increase the rate but I'd be...

Thanks! It's got MMR oil pump/crankshaft gears, otherwise stock!

I'm still learning it. I had to turn the rate down to 12 on my best run, otherwise it would hit high boost too early and the track wouldn't hold it. I was trying to slowly increase the rate on subsequent runs but ran out of time after several cars broke and caused delays. On lower boost I had...

I have Sai Li's return style system and E85

Hello all, I've been lurking on here for a while and thought I'd share my experience with the Hellion setup on my car...I have a 16 GT Premium auto that I purchased last March. I traded in my 13 GT500 (Grabber blue, 11k miles, beautiful) mostly because I couldn't ever get the shifter/clutch to...
