1st TVR Power Supercharger fitted to a customers Car
Discussion
Hi Chris. Thanks for posting.
Nice to see a 4L V8 SC getting closer to a SP6 4LRR.
The torque curve looks similar to mine even producing the same max torque @ 275.
Pleased to see it's still 40bhp at the wheels less than mine!
Although a 5LV8 SC will slaughter it. Dom get your finger out with the SP6 SC! We need it to keep up!
Any more work needed; mapping etc?

Thats only if you believe TVR's power figures for the T350C in the first place
Based on the same rolling road a few weeks back. Like for like and not calculated flywheel figures.
Mine developed 308bhp@6200rpm at the wheels. Would have been higher if Jason had taken it higher but he stopped there.
Anyone familiar enough with this installation to explain what all these hoses and things are?
There's a 35mm hose that comes out of the black air box and heads off round the back of the plenum, what's that? Perhaps a breather from the far rocker cover, but if so why's it so much bigger than the nearside one?
What are those two hoses strapped on top of the air intake hose? Oil lines, perhaps, but whay are they routed all the way up here?
What's that blue thing a couple of inches away from the stepper motor?

Paul you need a supercharger now. :-)

Is there an intercooler? The two black hoses could be coolant to/from a front mounter intercooler?

I've already offered my car to Dom as a test dummy for the SC installation with the promise I'd fully explore its reliability - free of course. No luck. He's got a new 4L SP6 engine lying round to go in his Sag - which he's going to increase to 4.5 and SC (if I remember).
As always, you can never have too much power...

Not familiar at all but could have a bit of fun guessing some of the above.
The larger hose (35mm) looks like it goes to the inlet of the plenum not the OS rocker, in effect a blower bypass
Agree the two hoses are oil/hydraulic, and go forward past the AFM possibily oil cooler or even rerouted Power Steering lines, but why up there is a good question
. The blue hose feed looks like it has a breather/relief type thing on the end and its connected to the plenum base.
Great wheel figures there, a lot lot lot better than most standard 5ltrs
. The only real query I have is why there is a significant difference between the off boost
figures in the before and after plots i.e. sub 2k3rpm at zero boost the 'after' already has +30lbs +10hp over the 'before'

Might be because they haven't measured vacuum. Reading 0 boost for both engines at them revs, the NA engine will be further in vacuum. So the SC will effectively be producing boost but not enough to reach atmospheric.
Just a guess.

Looks to me like the 35mm pipe is for the blow off valve, (this is simply putting the pressure back into the blower so when you lift off the throttle and the throttle plate slams shut the air has somewhere to go rather than try to stall the blower) the other pipe into the black box is the crank breather, the black box looks like its simply a way to get the crank case vent and the blow off back into the intake after the AFM and to turn the air intake into the blower, its not a cooler of any sort,

Good call, yes I had noticed the blow off valve on the far side but assumed it was a dump-to-air system. Given the hotwire it would of course have to be recirculating. That black box looks like an expensive way to just turn the air through 180 degrees but perhaps it was something they already had. Any idea what that little blue sucker is below the stepper motor?

Not sure, looks like its a T into the vacuum feed for the brake servo, could be a pressure sensor, no idea though, would be interesting to know though,
