Our Rampage is a lot heaver than Johnny's which is not a bad thing because it can take a beating. We made minimum weight at 1350 with no added fuel or weight on carbs not EFI.
We moved our seat and steering wheel back about 6 inches which helped but we need to add lift. So the Rampage will be derigged and turned upside down next year and receive a inch or so of lift in the tunnels. It's got 1 inch of squish and it needs more like the STV's

I know 1 way or the other yall will get it figured out , ill b pullin for ya til u do , was giving james few days to settle in and gonna call him bout motor and few other things , can't wait to hear bout new setup next yr

Jesus... if you're blowing up three engines a weekend you might look at your motor program... didn't you bust one or two last year too?

He has a point, something is wrong,

Looking at the missing piston, when my race motor does something odd, I shut it down, I've never destroyed a piston like that.

I don't know any west coast motor builders, Jay Smith's in Texas, fuel issue?, It's been 25 years since I've had a carb Merc.

Just bought a diesel pusher MH, hope to make it next year, would like to bring my boat, but I'm not going to change it to a 20in just to race.

15in motors are safer making corners that's for sure.

So how many Div 5 boats were there, how fast are they.?

That's what a 300xs on a 15 mid would run right.

You can read the rules on Ross Wallsh RPM web site. My guess is you already have.

Our motor program comes from a well known engine builder from this site who has been sponsoring us for a while.
My sprint racing 2L has been running hard for 7yrs and completed 5 Enduros requiring only new rings.
It has been on the same 1 piece exhaust with no problems.
When we decided to run the 2.5 and 2.4 oval port in Div VI we started having what we thought to be lean issues with a fuel injector and when we switched back to carbs (wh 46 and 20's).
We retarted the timing and fattin them up.
We've always ran mostly steel sleeved ported fishin motors.
Based on the help we've received by PM's by well known racers we need to look at cooling issues and water routing especially on the 2.5's. Thank you to those who are trying to help.
Learning curves suck and nobody likes a quitter.

Regardless of how "well known" someone is, three blown engines in a weekend is still three blown engines. No need to be defensive about it, I know there are learning curves in racing, we all do.

What is the cooling system setup like under your current engines?

The sponsor for bakers motors is 1 hell of a engine builder , i do know he has also stepped out of the box when building these , tryin sumthin little diffrent here and there and im sure there's gonna b a learning curve, he's got motors turnin 8k all over the United States and across seas that's living a happy life. I am little biased tho I admit , they will get one they like and figured out , best of luck Keith

**Noah Burns** · 11-06-2020, 03:54 PM

I know who the builder is, it's not exactly some kind of secret. The fact that he's such a super builder and still blowing these things up like it's his job is a little more concerning honestly. It almost seems like there HAS to be a third party issue (possibly the cooling as mentioned) or fuel system or something.

I wasn't being a asshole or nothin and I know most know who does the motor work , it sucks it happen and imo the cooling prob has lot to do with it , cant wait to see what hebdoes now

2 were my engines and 1 was another engine builder so it is most likely a common issue with our set up/combination. The 2.4 (fatblock 2.5 block style) lasted all race last year but we were feeding it a ton of fuel. This year it popped the same way the 2.5 did last year so there maybe something going on with the plate, block, ect. We are trying some out of the box things to gain advantages which can increase the chances of failure. The cooling issue is something that we are having to look into and maybe the reason for 2 engines being lost but the 2.5 suffered a different type of failure this year. Never had a issue with the earlier block only the 2.5 style. I am going to build a very close to stock 225 promax for reliability and then a steel bore 260 for power for next year. We will figure it out and be competitive soon.

Fluffy , you don't owe nobody an explanation for nuttin ...

Ifin racin was easy .. wee'd be callin all them railbirds with an opinion .. Champion

I know I don't. Just easier so people don't assume things because they are not involved or know the behind the scenes. This has been aggravating for sure. We are getting a jump on things this year and hope to get if figured out soon.
