Next Project
Ported it....
Done the 500hp+ build... Frankenplenum... Nitrous.... I think the only way to keep up with the jones is forced induction; Callaway had it right back in 87 and now everyone is running twins.....I have driven my Sl600 5.5L V12 Twin Turbo with 605hp and 700ftlbs most of the summer; its like the hand of god gets behind you and shoves you in an instant to 120MPH I am thinking a low boost TT on a 500hp engine would get me up to 2017 specs; forced induction is getting cheaper so its time! Or I just go buy a 2012 Callaway

Re: Next Project
Hope did the nitrous turnout? Did you make a new tube or bust throw some cooler plugs in?

Re: Next Project
The Nitrous went well, I will fine tune it in the summer and move to a 125 shot.
Hopefully the 91 project will be finished this spring...sell get it off the lift.....in the mean time will start planning TT layout and start parts search

Re: Next Project
The low boost TT project sounds neat. I would look at a single turbo to reduce plumbing complexity. With how efficient turbos are now you could get a larger single turbo that still spools up quickly.
I'm interested in the Nitrous route as that is the "easiest" and most efficient way for cheap power on these cars. I remember a while back I saw a direct port nitrous plate that sandwiched between the plenum and injector housings.

Re: Next Project

Re: Next Project
Cams, Compression, and a little more displacement--all natural. What are you waiting for? I can get you to 600, maybe 700.

Re: Next Project
My $10.5K ZR-1 has 520-530hp...on the bottle should be 605 to 655; I would like 650hp; like the turbo idea as it can be adjusted. For $700 my SL600 went from 495 to 600+...can't beat the boost.
