Cockpit placement on GRMR

butch nassau · November 18, 2011, 04:33:41 PM

It is not clear to me...few things are, so I'll ask the question:

Can the cockpit(roll bars.seat,etc) be placed behind, or partially, behind the original firewall.

As I am contemplating a four cylinder engine there will be adequate room to move the cockpit back if this is permissible.

I cannot tell from the few pictures I can lay my hands on.

Advice?

It's always best to consult the SCTA rule book:
5.B.1.a "The driver's seat shall be entirely in front of the engine."
(And the entire engine has to be forward of the centerline of the rear axle) So, if you can squeeze in somewhere, feel free . . .

That darn rulebook thing.

For instance...the harmonic balancer is in front of the engine but so is the front axle.

The rulebook says, "'streamlining ahead of and including the cowl...is permitted."

So I Guess that if the cockpit , or part of it, goes into the cowl area your okay."

I'm getting kinda punchy trying to figure this stuff out.

I have a1.8 litre Honda DOHC engine adapted to a VW type I trans axle so it is only about 24 " from the rear axle to the front of the engine. So the whole cockpit may fit behind the cowl. I'll start using that darned tape measure thing tomorrow and figure it out.

Are the fiberglass bodies from Speedway Motors and other aftermarket suppliers acceptable?

Any and all advice is gratefully accepted. I just don't want to get seventy five pounds of tubing , labor and fiberglass into this and....

I cant speak about others but from talking to Russ a while back he mentioned the Speedway body was not legal. Maybe they have changed the molds around and now its legal, but I would check with Russ for an official answer, the SCTA allows + or - 1" on the dimensions. I have the spreadsheet that Russ sent me with all the dimensions. Send me a PM with your email if you want it. We are using a Dick Williams Polyform body and since you are building a REMR, welcome to the dark side. Tony

I was just about to suggest looking at Tony's build diary. I'm not trying to steer you away from RMR, they look a little like lakesters except they must be wider at the back... Save yourself a lot of trouble, put your 75 lbs of tube toward making a lakester...a lot less rules and hassles.
Try not to paint yourself into a corner with your engine. Leave room to grow.

Thanks, where can I find the build diary?

I kinda like the idea of a ,maybe, 135 MPH record in "G" rmr. But, as far as a Lakester at 212 MPH?!...I don't want to go to the expense of having my heart stents bored .030 over to stand the excitement.

What record database are you looking at? I don't see a G/RMR record at Bonneville. This means they are all zero.

Okay,

If the rulebook says that "G" class engines are allowed and there is no record in the record book...doesn't that mean the record is open?

Or , maybe this is how it starts when your mind is trying to tell you it's time to take up lawn bowling?

Kiwi Paul · November 19, 2011, 08:22:16 PM

Dan-I think Butch is saying that he thinks he could build a REMR with his combination that might go 135 and set a record.....having seen that there is no record listed in the Rulebook, eg open.....Butch--don`t take up lawn bowling, I did it once, and nearly passed out from the sheer heart pounding fabulousness of it...

Stainless1 · November 20, 2011, 04:44:44 PM

Butch.... build a lakester... There is a lot more satisfaction in taking some SOBs record than setting the first number on an open one.... that and 212 is way more fun than 135.
Go for it

dw230 · November 20, 2011, 05:06:56 PM

Butch and Stainless,

I knew that, I was trying to get a little more exact for the peanut gallery.

If an engine class is allowed with no record listed it is in fact open and two consecutive passes will equal a record. Take a look at the 15 to 46MPH records set at this year's Speed Week. Butch will not have to go as fast as 135 to satisfy his needs.

Butch,

Joanie and I will be in Nassau in mid-Dec., is that your location?

Okay,
Thanks everybody.
I'm about to go to my potential sponsor.
I have yet another question...of course.
The question is:
Withe driver seated very far forward in the standard roadster body, can the drivers legs protrude through the firewall...'which cant be altered'...into a nose section toward the front of the car?
