    Supercharge or 2 litre?

    Thinking of mods for my 78 B this winter.  I'd like to get to about 110 bhp and I'm considering a 2 litre rebuilt motor or supercharging.

     Does anyone have opinions they would like to share?  Has anyone driven both?

    Cheers!Smile

    TrueBrit-

    I don't think it should be too hard to get 110 H.P. out of two litres and the car will still look stock under the hood. It seems like it would keep things simple and I believe you would also get better gas mileage since the engine would not have to be turning that supercharger all the time. Also would put less stress on components. I don't know how the costs compare but I believe a 2 litre would be as dependable as a 1.8 and I can't say the same for a supercharger. With the larger displacement you could go for an aluminum flywheel without harming driveability in stop and go traffic and this would make a significant performance improvement.

    Hey, what the heck, you could add a supercharger to the 2 litre in the future and really have some fun! (That is, if you win the lottery.)

    Thanks for the post. I've enjoyed spending your $ for you.

    Thanks for the thoughts, that's the way I was leaning but it's always good to hear others opinion. 

    Yes, it IS fun spending others money isn't it!

    Thanks again.

    I have a supercharger on my 71 and love the tremendous torque spread plus the whine gets pretty addictive. Only problem in 10,000 miles has been with the belt system and pulleys and I ended up redesigning the bracket and since then have had zero issues. On the other hand I am building a GT and seriously considering going with a 2 litre so I can compare!! Either way the supercharger makes the car a lot of fun!Stick out tongue

    Wyobrit-

    I'll bet if you put an early MGB head on your later model engine it will lower compression and increase combustion chamber volume which will, with a supercharger, increase power. Has anyone out there tried this? Is this the hot supercharger set-up?

    Hey wyobrit,

    Who are you? Where are you? I'm here in Ft. Collins, Colorado. It's your avatar that got me going. Do you know Ray Middleton? He's an old friend, and if you own that Spitfire, I KNOW you've heard of, or know, Ray. He's just a couple of hangars down from me at the old Ft Collins Airport. That's also a nifty three wheeler Mog there. We are restoring a '39 four wheeler right now in the shop, and do a fair amount of Morgan work. It'd be great to hear from you if you like.

    Hello Bill,

    I only wish I owned the Spit but I do own the Morgan which is a 1930 2 speeder, lots of fun and constant money pit. We have not met but I am up in Cheyenne and own the Midas franchise up here and have recently purchased Ft. Collins and Greeley, also have a radio show every Saturday which reguarly discusses British cars among many other things! Brought up on a diet of British cars and motorcycles growing up in Kent and escaped to US about 17 years ago. The Mog has been in the family for years and is now surrounded by a motley collection of other, mostly British cars and bikes.

    Hope to meet up sometime

    The engine is running about 7:1 and as long as it is carefully timed does not have any detonation problems, particuarly up here at altitude (6800 ft) Big Smile

    Nick,

    This gets better and better. My first automotive job was at a Rover dealership, and I fell in life long love with the P-6 cars, several of which I still have in varying states of repair. What may interest you is that I have three 3500Ss behind the shop which it now seems I'll not get to. Private message me if you have any interest. You can see our shop at  www.motorwayltd.com

    Tell me also about the radio show, please. On what station? I'd love to contribute if I might. I've been doing this for forty years. I've seen a couple things...

    M.B.-

    I'm concerned. I don't like your quote from your post, "I have three 3500Ss ...which it now seems I won't get to."

    I hope your  health is okay, we'd sure miss you!

    Sincerely,

    LCJUTILA

    LC,

    Yeah, I'm feeling fairly OK. Thanks for asking. It's just that I have skatey eight other projects to get done first and I'm not as springy a chicken as I used to be. I need to finish my '67 Rover 2000TC, My newly aquired '58 MG Magnette (an exact duplicate of my first car!), my boy racer MGA, and a radical BGT that will drop jaws IF we ever get it done. On top of this, I work on customers cars all day. I must admit that my status as an enthusiast gets harder to maintain around four O' clock each day, and these four will take just about all the devotion I have left.

    Remember, I still play with everybody ELSE'S Britcars all day. I don't really have to have a bunch of my own.

    Bill,

I would love to have you  on anytime! Call in number is 307-632-6500 or 1888-503-6500. I also have about 5 projects to finish plus the constant battle with the JAP in the Mog, and at the moment have a TR3 an E type and a couple of MGs in the shop plus all the regular stuiff that is the bread and butter every day. Wish I just could concentrate on the 'fun stuff'. as you have managed to do so successfully. I do need some parts for the remote brake servo on the 3500 if you have any ideas. If you get a chance give us a call tomorrow show is on from 8 - 10 am MST.

    M-B,

     Are you planning on taking your Magnette to NAMGAR’s GT-35 in Delavan, WI in July?  Magnettes are featured MG for next year.

    Re: Supercharge or 2 litre?

    Hey Motorbill - didn't realise you were a Rover collector as well. The P6 is fondly remembered by lads of my age as the Motorway Patrol car. I'm pretty sure there was a Matchbox/Dinky model that nearly every kid had in their toy garage!

    As for the original poster, I cant offer much except to comment on aluminium flywheels. One (the Moss supplied part) was fitted to my 67B on an otherwise stock engine by a garage too lazy to fit a new ring gear to the old wheel and machine it's clutch face I think. Anyhow, it hasn't affected drivability at all, as far as I can tell, but the engine is nice and perky for double declutching Smile
