Not really, was there an SCCA determination, for this class ? The Sunbeam Tiger is allowed 260". What's the deal ? Mushroom lifters,(VW based), are needed, and a genuine racing restrictor carb. Do the rules state, the restrictor must be "below" the carb ? It dows say 4ithin 4" of the butterflies/but ? roverman.

Looks to me like the RV8 got limited to 3.5L because it was lumped in with the MGB/GT V8 & the TR8.

Maybe Phillip or Curtis will chime in on the specific restrictor rules. As much as I love the RV8 that Phillip has built, I don't see how it can be competitive in this class.

Same ol' story, privateer calss, but spend like a corporation, if you want the class championship. Beating the class leaders, with an obsolete design, will be expensive, at best. Perhaps better to just have fun, and save your small fortune ? Good Luck, roverman.

Just like the SCCA I remember....If your a racer and not competitive, get on a "rules committee" ! Then change the rulles to favor YOU ! GT2 blues, MG RV8 is required to run obsolete 3.5L heads, in a non-vintage class ? Not even "stock replacement" aftermarket heads ? This stinks, and is another prime reason, not to run SCCA ! Regretfully, roverman.

I 'luv it, get on the race committee. Yep ... that's the best way to get changes in the SCCA GCR (General Competition Rules). But getting on the General Competition Rules Committee requires years of service in the SCCA and a load of experience in all the different auto makes and drive train components and safety hardware and on and on and on. I know a few of the guys on the GCR Rules Committee and I know that I certainly have no place on the GCR Committee.

As far as I know - for I haven't seen the latest 2015 GCR and I don't think it is available yet - but there will be no change in the rules for the GT2 RV8. I'm still restricted to the 3.5 Rover V8 ( even though the RV8 came with the 3.9 V8). So I'm building a new 3.5 engine with better heads, cam and compression. I've got all the parts - disassembled the old 3.5 - and plan to have it all back together for the 1st SCCA race at the new road course built into the Kansas Speedway - on June 12, 13 & 14, 2015.

I'll have several free pit passes - & let me know if you can join me in the pits. I can always use help in the pits.

I'd like to point out that I plan to win the race and would never enter the competition if I didn't think I might have a winning car in the Rover (MG) RV8 - even with the smaller 3.5 engine. In the past few years of racing the RV8 in the SCCA ( National Races) GT2 class .... the RV8 has entered and raced in 8 races with 5, 1st in class GT2 National finishes - and did finish the other 3 races. Five out of 8 ain't bad.

The reason the Rover (MG) RV8 is competitive - even with the 3.5 Rover V8 engine in the SCCA National GT
2 class is because of the weight - and the big brakes and aerodynamics and handling - but mostly
because of the RV8 allowed" weight @ 2,101 lbs ! Most of the cars in the GT2 class weigh over 3,000lbs. Many weigh over 3,500 lbs
By the way - official legal weight is "posted" on every GT2 car. The RV8 wears 2,101 lbs posted on the drivers door. The RV8 with the driver aboard barely hits the 2,101 weight requirement ( taken at the end of every race).
The RV8 GT2 car weighs 1,600 lbs "dry". With 24 gallons of fuel in the fuel cell, 14 quarts of oil in the sump, 200 lbs of lead weight and a 200lb + driver ..... the RV8 has always cleared - barely - tech inspection and the weight spec at the end of all 8 National races entered !

I have 7 months over this winter to prep the RV8 for the Kansas Speedway National SCCA Races - on June 12, 13 & 14, 2015. I get several pit passes with my entry. Join me in Kansas City. I could sure use your help.

keep them on the track,

If there was something close to Kentucky or West Virginia I could try to come, maybe even bring Dan.

Jim,

Sure wish I could plan a SCCA National race in Kentucky or West Virginia, but I think the nearest venue is the Mid Ohio track. Ran there several times in a Sprite and a Datsun 510 - years ago. I think Mid Ohio is the best SCCA track in the country - would love to run the RV8 at Mid Ohio some day. I'll try to let you know where the RV8 will be entered into an SCCA GT2 race near you - "Back East " - someday.

keep them on the track

Mid-Ohio is probably the closest. We've been there a couple of times. I'll never forget the Mini/Sprite challenge through the madness at the end of the straightaway (you know the one). Someone popped a radiator hose, you can imagine the results.

Hi David,

Good to hear from you.

You probably know that I got a set of good Buick cylinder head from Dan Jones (BIG VALVES & PORTS !) .... but .....
I decided not to use them in this rebuild of my 3.5 Rover V8. I decided that it would bring just too much attention from the SCCA Tech inspectors.

Getting through Tech at the end of a SCCA National race is chore enough with a perfectly "stock looking " Rover V8 - and those beautiful Buick cylinder heads could well lead to a protest, a tear-down and a nightmare at the end of a very long & out-of-town return tow home. Been there-done that and will avoid that scenario.

I've highly modified the (mostly stock) Rover cylinder heads that I have already used in 8 SCCA National Races, this time around - porting, polishing, flowing, cc'ing and changing compression just a little. I've improved on the valves and springs, too and have gone to a new Crower race cam.

The most important change is to the Edelbroch intake manifold - so that it now matches up to the tiny (SCCA mandated) restrictor plate that I'm required to use with the world's smallest Holley carburetor - a Holley
390. The SCCA rules make it very difficult to compete in the GT2 class with a MG / Rover 3.5 RV8. FYI .... I've had to remove the 390Holley carb once before to the Tech Inspectors - to reveal the the restrictor plate.

I plan on putting the RV8 on the same dyno near my garage - where I last found about 175 HP. Hopefully with the new engine - I might see 250 HP, with some good luck.

I hope you can join me at the new road course built into the NASCAR Kansas Speedway - June 12,13 & 14, 2015.

Could sure use your help in the pits and maybe you could even get Dan Jones to make the trip with you from St Louis to Kansas City.

keep them on the track,

phillip g

Yes the SCCA is far more friendly to the big name manufacturers , that's where the bucks and the perks are for the club, they are probably apoplectic over the performance of the LBCs at the runoffs this year LOL . well good luck next year Phil, MID OHIO in 17 !
