Ron Ron the only thing is that it is really designed for low compression US engines and it needs a major rejig to work on anything over about 8:1. If you want any more info talk to Jeff Marks at Moss as he can give you chapter and verse on the kit. Stuart. Quote Link to post Share on other sites

Tom Fremont Posted April 18, 2007 Report Share Posted April 18, 2007 Ron, Â If it's more power you want and you've already got the P.I. head ( what about the cam? ) you can fix yourself up with a second-hand set of Webers for a lot less cash. Don't be concerned about second-hand; I've got 70,000 trouble free miles on a set of really ancient ones ( with brass throttle shafts ). Â Now that Webers are back in production the used ones will be reasonably priced for a while yet Quote Link to post Share on other sites

Guest ron Posted April 18, 2007 Report Share Posted April 18, 2007 (edited) Jon You know my opinion of the PI set-up [if I'd designed it I wouldn't tell anyone ] Tom Wouldn't mind Webers, it's just the supercharger is something different, anyway I've just spent over £1000 on steam engine castings etc so they're all relegated to 'another thing I'll buy if the lottery comes up' Ron Edited April 18, 2007 by ron Quote Link to post Share on other sites

My engine is a CR 125 HP engine with a 7,5 compression head, the injection is converted to Bosch L-Jet from a Opel Senator 2,5 donor car , Eaton M62 SC. My TR6 use 7,8 seconds from 0-60 miles and that is before I have added the intercooler. Take a look at this video.  Oystein   Edited May 22, 2007 by tr6driver Quote Link to post Share on other sites

Ron   I think it is a good option and comparable to a lot of machining and new parts. You do have to have a good solid motor to start with so chances are you are going to spend half as much again on refurbing your standard engine before you add the SC but it does look good and I bet it sounds impressive too when it is cranked up.  The part I noticed most was the "stunning" price, I was truly stunned when I converted that to dollars. Moss in the US sells that kit for $3500.00 or around GBP 1750.  Stan Quote Link to post Share on other sites
Andy Moltu Posted April 19, 2007 Report Share Posted April 19, 2007 I think tyey were claiming a 40% power increase for a US spec engine so it seemed a lot of money for the power increase compared with a head skim, camshaft and new needles for the carb. Quote Link to post Share on other sites

Still, the 7.8 second figure is not much better than the testers got for the early TR6 PI... Â Hi. Â I think I am able to get the 0-60 lower when I have fine tuned the injection and added the intercooler. The test result on 7,8 seconds was only done once , I havent reinforced the diff mountings yet , that will be done very soon. The engine power is theoreticly calculated to aprox 180 HP with this figure. I think on adding the intercooler and fine adjustments on the injection the car should make 0 -60 on 7,5 seconds with an engine giving about 190 HP.I dont think I want more because of the limits of the standard driveline. Since the engine power is up to the limits of the driveline I allways must have that in mind when driving. Compared driving a standard 150 HP PI engine there is a noticable difference in torque and power. I dont want an engine you have to rev up to 7000 RPM before you have the max power output . With the supercharger you can have high power and torque on much lower RPM. Â Â Oystein Quote Link to post Share on other sites
Guest ron Posted April 19, 2007 Report Share Posted April 19, 2007 (edited) Tom I think 7.8 secs to 60 is very optimistic for a TR6, back in the early 70s I had an Elan SE which was quoted at 7.9 to 60, it was CONSIDERABLY faster off it's mark than my pal's TR6 and any other ones I met, in fact the only car I ever met that it couldn't outdrag was a V8 Morgan.

Since I was the pilot for the test I expect it's really good for a bit better, as I wasn't about to thrash it within an inch of its life Edited April 21, 2007 by Tom Fremont Quote Link to post Share on other sites

Ron  Few TR drivers have experienced a supercharged engine with its smooth torque that starts at 1000rpm and just keeps coming as the revs rise. I'm convinced that once that kit gets fitted by a few members we'll be hearing rave reports. Moss must be onto a winner here. My Wade-blown motor takes 9psi boost at 5000rpm on a 9.5:1 C/R, providing I use 95octane fuel plus 2 octane-points of Millers dope (see the Technicalities CD). On a single SU with no fancy cam, no air-flowing, no balancing, no tuned exhaust.... And at full boost the engine is in effect working at 11.5 C/R: that's racing engine territory (and the exhaust note sounds like it).  Supercharging would make a good topic for a discussion meeting at the International. Anyone got a Moss-blown motor to bring along? Quote Link to post Share on other sites

Guest P Cobbold Posted May 18, 2007 Report Share Posted May 18, 2007 Moss catalogue says it only fits left hand drive cars. Regards Phil The carb and clutch m/c would probably be fighting for the same space in RHD. In the 80's Protek built a supercharged RHD TR6 with a big Marshall blower where the Eaton sits: the carb was fitted above the distributor. So here's an idea: put the battery in the boot and fit a single 2"SU in its place. If Moss give me a kit I'll do it for them, and in time for the International.

I was going to add a few 'toys' to mine,but I have decided to keep it 99% standard,and put the ££££'s to better use,like getting only genuine stanpart parts where I can!! Like wheels!!

I bought,fitted,then sold a set of wires, in favour of the original steels with chrome finisher rings.   I think it would be a shame to butcher an otherwise good injected engine with anything (webers, SC etc) but for the carbureted engines the SC is a good option and compares well with the cost/benefit for traditional tuning via normally aspirated means (c/r, cam etc). The SC is a good way to get closer to the original injected HP in a weekend assuming an otherwise sound motor.  Stan Quote Link to post Share on other sites
Tom Fremont Posted May 21, 2007 Report Share Posted May 21, 2007 I think it would be a shame to butcher an otherwise good injected engine with anything (webers) Â Aargh! I'm cut to the quick.... Â Actually a number of formerly injected cars are running with triple Webers - they can always switch back to P.I. if they want. What they get with Webers is performance, reliability and vintage cachet. Â It seems to me the supercharger option is presented as an easier way to get "there" but, as Alan says, you can buy the pieces for a P.I. and bolt them all on without much head-scratching there either. I've seen several TR250s and TR6 carb cars offered in the U.K. with P.I. conversions Quote Link to post Share on other sites
Guest P Cobbold Posted May 21, 2007 Report Share Posted May 21, 2007 Supercharging is no good for racing. The regs will put you in a class with the V8s- a 40% cubic capacity penalty. That's how effective forced induction can be, when taken to its limits. I drove my PI'd CR motor for well over 150,000miles. Now the PI kit is slowly gathering dust in a box in the loft. And there it will stay. The supercharged car is vastly superior - smoother, much more-low down torque. The car pulls a gear higher than normal, and feels overall very much like a V8. And that from a DIY conversion with a 50-year old blower from a diesel truck, (which limits max rpm to 5000), fed by a single SU and with near zero expenditure on tuning.
