My friend does the TT setup on 355's, I don't know the exact number but theres alot of them, most of them are challenge cars running on the track, none of which have any problems, extremely reliable.

The turbo's seem to be sitting pretty far down stream from the exhaust manifolds..

Would be interesting to see and feel how it drives.
I have the dyno sheet somewhere I'll take a pic of it and PM it to you, although the spool isn't bad.

I saw Hubert's car get built up, my friend is the one who does all of the crazy setup's at that particular shop, and does the tuning.

I believe CS's put down ~340rwhp, although I'm not 100% positive.

Those numbers seem really weak. What's the point of twin turboing such a car if your gonna run it on such low boost? I know it's to maintain reliability, but why not just go ***** out and build the motor? I know it would be hella expensive, but it would definitely be worth it if you decided to head this route.

I'm really curious how this car drives.
Its not that bad on a power aspect, the car puts down 550rwhp on such low boost, I believe the drivetrain loss is around 14% on Ferrari's, that would mean at the crank it puts down 639 crank hp, which isn't bad at all. Although I agree with you, it'd be definitely alot better if the motor was going to get built.

In a few days I'll go down and ask my friend for a ride.

Awesome project!!!

Really the motors in these cars are so high strung that you're forced to boost it to see any major power gains. The setup looks great, very nice welds on the aluminum.

People talk of building motors, would that have to be all custom work? I wouldn't think there would be enough of a market share to make a production run of strengthened 360 cranks/rods/pistons

For the most part it'd be all custom.

Maybe i'm the only one who understands the parts and whats going on, but that absolutely looks like ***.

Why use those pos, cheap *** barrel intercoolers?

He couldn't hide those hideous lines going to/from the IC's?

Couldn't manage to come up with a better way to route the intake tubing rather than it snaking across the engine bay?

The intake piping is how close to those red hot turbine manifolds?

Sorry but i'm not even the least bit impressed what so ever.

I assume your speaking about both setup's?

I think its alot easier to critique a job from a person looking at it opposed to the person who had to deal with the space constraints etc.

The setup is also tested and proven, with alot of time spent on the track in wide open throttle hot temperature conditions, beaten up and driven to the limit. With absolutely no problems and performing perfectly.

I'm speaking from personal experience after designing and building many TT systems fit in MUCH tighter engine compartments, and making near 1600rwhp.



Tested and proven... against what?

It's proven because it didn't blow up? Thats 100% tuning more than fab and design skill.

What does the dyno graph look like? How much does the torque fall after peak? If it's more than 7-10% from peak to redline the design efficiency is ****... <5% is considered good.

What are the air intake temps at the intake manifold?

Exhaust backpressure measured at the turbine?


The guy used flat head screwdriver worm gear clamps on the intake piping. On a $200k car, give me a break.

I couldn't stay for long so only snapped a few, these are the best ones, in a few days I'll swing by again and take more, the car will be clean then too. I have the dyno sheet, just gotta snap a picture of it and upload it.

Stupid me, it makes 375ft-lb of tq. Uploading the dyno sheet now.
