Peter Burgess, renowned UK tuner of MGB B series engines is thinking of bringing over a suitably prepped MGB for Bonneville speed week, and is looking for any information about MGB's that may have run at Bonneville.
Peter will run a 1950cc B series engine so 4 pot engines more relevent, but news of any B's would be interesting.

Just FYI, Peter has posted a thread on the MGE BBS in the "MGB General" section.
Bill,
Yes plenty of MGA stuff including the factory record runs but nothing has come up from searches so far re any MGB's having been run at Bonneville, rhere were no factory sponsored cars so it would be privateers only.
Steve,
Yes obviously aware of Peter's post over on my side but said i would widen the search for him.
Regards,
Kevin.
I hope Peter is a member of the SCTA....tech is weird enough that he better have the correct roll cage setup....and rent the DVD "Worlds Fastest Indian".
A stock bodied MGB would run in G/GT (up to 2.0L)...class record is 157.869 mph
An MGB with a modified body would run in G/GMS....class record is 163.441
Add a blower and the class becomes G/BGMS and the record is 230.352
I know nothing about top speed records other than I would love to see Bonneville one day. But these record details intrigue me.
A stock bodied MGB is only 6 mph slower than a modified body? Is there more to the story than that? Wings, air dams, no windshield? Are there any other details on why such a small difference and what is their definition of a stock body.
Thanks,
Richard

No, no, that doesn't have anything to do with what an MGB would run, they are just class records for the classes that an MGB might run in, depending on its configuration.

I have been going to Bonneville for years...never seen an MGB running. They are at a disadvantage I think. Cars are classed by body type (sports cars, sedans, etc.) and engine size.
An MGB would run in grand touring sports (known as GT). An MGB with a modified body would run in modified sports (GMS)...meaning unblown, gas, modified sports. Add a blower and you get (BGMS)...blown, gas, modified sports.
Engine size determines class. 1.5-2.0L runs in class 'G'.
The record for G/GT is 157.869 mph
in G/GMS....class record is 163.441
in G/BGMS....the record is 230.352
Don't forget....a 2 litre 911 Porsche will also run in this class...........
Ahhh, I understand. That makes a lot more sense.
Thanks
Richard
Heck, I think these MG's we all love are at a disadvantage just about anywhere except vintage events. Unfortuneatly time keeps marching on, and advancements continue, and other newer more advanced cars keep getting grouped in with ours in the "catch all" classes, and we get farther, and farther outclassed by more modern stuff.

From the highway, I-80, the area is just a continuation of the flat nothingness that exists for hundreds of miles across Nevada and Utah. Amazing that the Shoshonee tribes could live there 170 years ago.
The "World's Fastest Indian" flic was quite interesting---I can't quite believe the stunts Monroy allegedly pulled in that movie (shoe polish to make cracked tires look new, etc).
There is always the option of running 'Time Only' to see what the car will do if you feel that there is no point in running a class...or it doesn't fit into a class which is a problem I have.
The car still has to pass tech for it's speed capabilities and the rules/regs are unbelievably strict. Join the SCTA and get a copy of the rule book, have a read on Landpeed.com forums and ask questions, the inspectors are very helpful and would rather pass you than fail you so will give you as much help as possible beforehand.
New builds for 2010 onwards and existing cars for 2011 onwards now have to be ables to have the full Hans or equivalent safety equipment.
You have to go to Bonneville at least once, it is an amazing place, I shall be back out there in 2011 this time with my car if all goes according to plan.
Last time I was there I drove this....

A word of warning, the place is addictive...salt fever....and you'll find yourself wanting to go back again and again and........
Ian, I'm curious about your intake system, the small inlet particularly, aerodynamically ,obviuosly it is cleaner,are you making good power at the end of the run! BTW; I love 27 T roadsters!

Aerodynamically it's horrible.....:(
The engine is a Mercedes V8 from the 70's and is running fuel injection system with the ram air intake housing the butterfly, electronic ignition and all controlled by an AEM programmable ecu. A ridiculous amount of compression, a lot of balancing and a fairly stock bottom end. :D
The gearbox is a TH350 with manual shift conversion.
The car makes good power all the way through a run,as you say mainly due to the air intake. It wouldn't get enough air flow to the engine if the intake was inside of the shell and there are limits to the aerodynamice modifications that are allowed in each class.
Unfortunately this engine is no longer class competitive as the record has been taken now by a car with an Aurora engine producing more than twice the power. The Merc engine is on the ragged edge so there is no way to compete so the only option is a new power plant...it will be back! :smoking:

Here's a pic of a car we have helped on the composite work, it also has an Aurora indy car V8. Basically it is a Berkley with
an Opel gt front clip on it,it is owned by John Stieger,he and Gary Hensley(200 mph club) are working on getting it ready, last year they had difficulties with the preheater etc. and could'nt get in a run.
Here is a link to some modern MG recordbreaking.
