- The 2.0L Supercharged Rover V8 engine has been extracted from the TR7/8 shell that it didn't quite fit, and plumbed into the RPi engine test bed to get up and running.
Cool! I remember reading about the _'Italian 2.0L TAX specials'_ back during my two stints at Triumph TR8 ownership, the first from 1988 to 1998 with a 1980 TR8 w/ 390cfm Holley, then with a true 10K mileage 1981 injected TR8 beginning in 2012.
Mannnn i love this project...really fan of small capacity engines with more than 5cyl!
Beautiful piece of engineering there!
You are very precious. Your engineering knowledge is invaluable
i dont like the look of that silicone hose collapsing, looks like a problem waiting to happen, maybe a stiffer or a ribbed silicon hose might be needed other than that it sounded sweet.
Yep, but of course this pipe work was just a temp solution to run the engine on the test bed. In the car it will be hard piped to a inter-cooler.
You can see the bonnet bulge was designed for this engines intake and supercharger location.
Awesome ... cant wait !
That engine is an animal!
Lovely.
dear sirs, where may i find a stroker crankshaft kit (not a buick 300 crankshaft modded to work in a rover v8!)for a rover 4.0 v8 engine??
I know TWS in the states sell a stroker kit but they make it by offset grinding a 4.6L crank, dunno what pistons and rods they use though
How cools that !!
How come the change of plans, with the engine now on eBay?
R/P. Sprintex supercharger we suppose ! Would it fit better in a transverse setup similar to repowering a Lotus Esprit ? V.
Hi Ian,
We need to know how much power this engine makes, dyno run please.
By the way there was also a supercharged version of the Tasmin called the SX350. See CARS AND CAR CONVERSIONS magazine from september 1989 with a road test by reknown journalist Paul Chudecki. See also AUTOCAR from the 20th september 1989, p.52 is an article named "Level 42" about driving a Sprintex supercharged TVR 350.
Keep on your good work.
Chuck it in that Sd1! Better still get a 2000 Sd1 and stick it in that and keep the badging.
Huh. Whaddaya know? That's pretty cool. Flat plane is cool. How's the balance? I wonder if that could be replicated on a 4.0 with a bigger crank and bore and custom cam.
It idles reasonably well but unknown for sure at the moment as its running on a 4.0 litre fuel map so is rather rich and dull.
Is it done yet? 😇
lol :-)
Where did you source the camshaft for this engine ?
Its the original fitment cam. However we work with both Kent and Piper should you or we need anything special.
What was the problem with the original engine from the V8S?
Nothing at all. V8developments 4.0 liter build and drives incredibly well. It will likely be available for sale.
So your removing a perfectly good v8 to put in a smaller v8 with a blower? Wouldn’t it be better to find a 6 cylinder to put it in instead?
The V6 models from what we could research had a very different chassis meaning to fit a V8 its a lot of work and also V6 moded to fit a V8??, NAH!) Better to start with the right car. :-)
Ah I didn’t realise there were chassis differences still think I’d opt to put the supercharger on the v8 already in the car be far more fun. 😝😂😂
It would be too small for the 4.0 litre engine.
What happened to twin turbo Tuesday?
Its still happening but as always is at the back of the que as customers work takes priority. The only thing left is finalizing the petrol ECU. Dyno tuning went very well however just didnt hit all areas an light throttle on the road still is not right hence no update / final video. Covered around 3 thousand miles now on LPG (ive done some basic mapping on LPG so I can use the truck) and all that have been out in it have been amazed at the instant power available.
@@RPIEngineering excellent and Tha ks for the reply.
Any idea on what power and boost its at right now? How's the auto holding up?
@@psiwog around 6 to 7 psi. Power levels on the dyno were between 350 and 400 bhp and equal lb /ft torque however the rollers were not calibrated properly to the engine rpm due to torque converter slip during calibration hence why Im saying between 350 and 400 bhp and not the 400 bhp that we first saw or the 380 that we saw at the end of the day once some timing had been pulled out. I will get there and a final video will be published with a dyno run on the same dyno that the project started on so that we have a fair comparison.
@@RPIEngineering that's incredible given its 4WD, auto and low boost 😳
@@psiwog These are crank figures not wheel.
but why reduce the capacity of a v8 so much ? i'm sure there was a good reason but seems silly to me
Originally designed to get round Italian emissions laws.
@@stuartlindsay8136 thanks for clearing that up for me
The BMW E30 320is was made for the same reason; the M3 had a 2.3l I4 which would have been heavily taxed.
