Standard sequential and its the bomb !!!!

You will find most run single due to less heat, less complicated turbo control, more power, and which turbo is really pending how wild you want to go. Happy medium seems to be t04r/s, gt35r, tdo7 or turbonetics kits like the t60.

For street driving the seq delivery of the twins is a thing of beauty, full boost from 2k!!

Have you looked at the bnr stage 3 sequential turbos apparently they can make 450 but I would have thought it would be pretty hard

The bnr seq twins have been tried a number of times over here but the claimed big numbers have never been seen. That and the cost of them plus import fees etc just makes them a crazy choice over just going single if power is your thing.

The same applies for knightsports rf420s etc

I know I keep adding new questions but has anyone had experience with the revolution twin turbo setup they claim 470 horses and would think it would be a nice setup to use thanks

A good delivery and quick spool tbh with enough power (450-500) I love the t51r for the noise but my mates RX has one and the lag can be quite bad I think full boost by 55-5800 rpm and his revs to 8k, so not much of a power band, I want a power band from about 2-3k all the way to the limiter, if poss

the only uprated Twins that actually perform that I have mapped are the Knightsports, 370 rear wheel horsepower.
BNRs have been dogturds to be honest never make the power clamied, mapped 3 always been disappointed, only making an extra 10bhp - 20bhp over stock twins

I\'ve just switched from non-sequential twins to single GT35 - a screw came loose from the inside of the throttle body, wrecked half the engine and the rear turbo :( I figured, with the twins getting harder to maintain I\'d take the opportunity to go single while the engine was rebuilt. Also gives potential for development of the car over the next few years when I can afford some more bits.

Currently mapped to just under 0.5 bar with standard fuel system, rad and IC. I\'m running a large street port. Estimate 320ish BHP from builders, and man it is LOUD when she comes on boost :Thumbs-up

Single turbo TDX61
TDX61R is arguably the best street, and medium frame turbo for a 2 rotor engine. This water-cooled Ball Bearing turbo provides the fast spool of our standard TD61 Turbo(61mm-500rwhp), with the power of a To4Z Turbo(67mm-550rwhp). This turbo features A TurboSource 11 blade 61mm billet compressor wheel. It " spools" 500rpms faster than a TO4Z while still being able to support 550rwhp @ 25+psi( E85 or race gas). The turbine section is a 74mm P trim wheel, which is very well suited for the 15 to 25psi range on a 13B 2 rotor. The larger 74mm P trim wheel outflows the 68mm Gt35R turbine wheel considerably above 18psi. We have seen as much as 24psi by 3400rpms in 4th gear on the dyno. Most end users report 400rwhp @ 15 psi, and 15psi by 34 to 3600RPMs.

not yet, I need to tune my ECU.
I do some log to see better what to change and adjust to  my AFR.
I do not have much experience in this field, I will help with some of my Italian friend more experienced than me :)
