I had the opportunity to visit a really talented machinst/fabricator that restores vintage racing cars, and does full chassis prep, and motor building work for all types of race cars. I had a really great time and thought that i would share a couple pics and some interesting info about some things i didnt even knew were in exsistance.

The shop is called DSI, (Dean Sellars Industries)

The first car is a McLaren M6 (its an old CAN-AM car) That was completely built by this one man at this shop, practically EVERYTHING was fabricated in house.




Small block 350, with custom mainfolds and custom sized TB's All tuned with electromotive TEC3



More pictures of the same car, you can really see the detail of all the riveting and suspension work that was done, really neat.



Thats correct, that car has a custom fully functioning AC system. 16 inch wide wheels.

NOW HERES THE TECH QUIZ...

Can you guess what kind of motor this is?
How much boost?
Displacment?
Manufacurer?
HP?





And, How do you think this Turbo works?




Ill post up the car that motor belongs in at a later date...

and one last picture...

cool ****, im kinda curious how that turbo works

 

Thats one mean looking car.... Any pics of the whole car?

 

everything looks good

 

The turbo works by varying the fins on the compressor and/or exhaust turbine.. And I think the displacement of the motor is 302CI..

 

I'd like to know more info on both, especially that engine

Right on the turbo, (i thought that was really cool, when i saw it, it varyies the amount of air coming in to the turbo with little fins to assist in spool up...because that motor pictured ran FOUR BAR of boost

Oh, and WAY wrong on the motor.

more information coming soon...

 

is that motor a 3 cyl, 6cyl, or 12cyl? Looks like it either is a v6 or l3 with bifurcated exhaust ports , or it is a v12.

 

ok ill spill most of the info...

Twin Turbo Renault V6

1.5 liters
12,000 rpm
4 bar of boost
Drysump
Variable vein turbos
7.5:1 compression
approx 6 inch thick intercooler core.
1000 hp

THe motor went in to a John Player Special Lotus from the mid 80s, i have pictures of that car too (not may though) Nigel Mansel drove that car.

Funny story is that the guy who previously built the motor for the customer used some off the shelf valve spring that only had 50lbs on the seat. Well if you think about that if your running over 50 lbs of boost, whats the valve spring doing? Some of the things that you have to take in to account with a serious turbo motor like this one is just out of this world. ill post some more pictures later tonight if i have time.

Thanks for looking!

I thought you were talking about the can-am motor.. And the variable fin turbos are on the new Ford powerstroke diesels, I think Garrett makes them..

 

Did they say anything about the ports on that renault? I have never seen that on an exhaust port. I don't know why they would do it, unless to try to reduce the turbulence after the divider on a siamese port. I guess every little bit helps when you are making that much power.
