Mad Hybrid Review
I have had the hybrid on for a few days and have been playing with the tunes to get it where I want it. I am running Renegade Diesel 190/75's with the hybrid that has the cast wheel, stock fuel system, so this review is based upon my tow/daily tune only. I know I can drop the fuel pressure to next to nothing with my extreme tune, so I don't even bother at the moment lol.
First blush, not a lot of difference in the egt's vs the powermax. Boost comes on quick and will max the insight quickly. I need to hook up a mechanical gauge to see what it is getting to, just don't have the time.
After several tweaks of the tune, I have the egt's down quite a bit. Max I have seen is 1250ish at WOT in o/d at 100 plus (tested on a closed course naturally).
Cruising at 70 egt's are low 700s. 75 to 85 on flat ground I am at around 790 or 800. Boost is running around 8 psi.
I get a small puff of smoke if I nail it from a stop, and then nothing, truck pulls very hard in this tune, boost if comes on faster and harder than the powermax.
There are two distinct sounds from the intake side. A deeper howling sound and then when the boost gets to around 10 psi or so, it sounds like a leaky window on your house on a windy day. I thought I had a leak in the y-pipe or somewhere but couldn't narrow it down. Then I put my stock intake back on and viola, no more noise. The truck is really quite until you put your foot in it, then it will get a nice exhaust note, and just take off.
Overall, I am impressed with the turbo. It pulls hard, low egt's no smoke in my daily tune, all I need to do is hook up to a trailer and check it towing. I like it.
I have been working with Eli on his setup, 175/75 and the hybrid, and he seems to like it as well. I will let him chime in with his thoughts if he wants too.
I will be getting with Adrian to see about the new wheel and will update from there.
