Yeah i was thinking the same exact thing. Not only that but not a fan of cutting the naca duct at the front of the hood to fit the IC piping. surely that could have been done another way...

Gravity drain is a nice plus though...

I like the idea of larger turbos that will still boost down low - 5psi on a big set of twins down low could be all the tires can handle anyway, then you have the top end only the big boys can deliver as boost ramps??

Correct it has everything to do with the way the boost controller is set to come on. A large turbo will not hit as hard as a small one. Power “under the curve” suffers a bit however, when you are talking north of 800-900rwhp that’s a GOOD thing.

I have 6266s with built motor and ported heads. The spool really kicks in at about 3000rpm. I made 1015 rwhp at 11psi and 1027 TQ. I have had it as high as 15psi, but not on the dyno yet. I would guess I am 1100+ @ 15psi. The tire spin is a challenge, but with a good standalone EMS, you can tune it to be more well mannered. The Toyo R888s definitely helped. I am at 3psi in 1st, 6psi in 2nd, 12psi in 3rd and 15psi in 4th+, but I also ramp up the duty cycle in the higher gears so the boost builds as rpm climbs, otherwise it will shoot to 15psi by 3500-3800 and be too much. I would say 67s would have been a good turbo for 1200, but I have not ridden in a larger turbo viper so my experience is limited.

Part of the problem you are gonna run into in there cars is that with bigger turbos you won't hit full boost until very high RPMs. With my turbos I am at full boost at 4200 RPMs and I redline at 6.5 or so. Doesn't give you a lot of room to play.

On my Lambo I have full boost around 4000 RPM but I can go to 9K.

It is strange. on the lambo I cruise at 70 at 3K and on the Viper is about 1300 RPM.

A little smaller but quicker spooling turbos might be a better street application.

What turbo size and AR is that to not get full boost until 4200rpm?

I don't know the AR, but the turn size is a 78

I'm running Comp oil less 6767's on a built Gen 1 motor. Makes over 1100whp on pump gas. They would easily eclipse 1200rwhp with good fuel. I had 7879s before, too laggy for street driving. I would NEVER run bigger turbos than the 67s unless I wanted more than 13-1400whp... Personal preference I guess.

Thats good to hear. How well are the comp oil-less holding up for you? I like the idea of them, however i've heard way too many horror stories. Then again, you only really hear people complain about stuff and dont usually hear the good.

I haven't had any issues with them, and from what I've heard, most people that had issues, had them with the first generation of oil less turbos. I would recommend them to anyone.

How long have you had them? I love the idea of them but all the reviews and negativity scare the hell out of me for the $$$. Its almost impossible to find anything out there that speaks positively about them.

I've been running them for years. Dan Lesser has a bunch of customers running them with great success also.
