Wow 8,225rpm

I cannot imagine what that must sound like .

Cheers chaps

Oddly, while 8,250rpm is indeed bonkers, it's as smooth as 6,500rpm was in stage 2 form I'm already very comfortable winding out Monty's Duratec to 8k and beyond, this when 7k was the end of the world before.

Monty seems to enjoy it too, but he'll never pass the 100DB noise test at Castle Combe without his DB killer.



The following is also now a must!

Remind me to do an Environmental Check the next time you are with us at Prescott. But you'll be allowed a bit more than 100dBa

Pass or fail... it'll be great to see you again Graham

Thanks Dave,
Unless you are actually competing we don't normally check sound levels, unless the vehicle appears to be excessively loud.
Regardless, look forward to seeing you and Monty at Prescott again soon

We already know Monty's gearing, and now we also know he revs to 8,225rpm.

All this means we can very acurately calculate his maximum road speed in 4th gear.



Not too shabby for a relic

AI predicts Monty will be aerodynamically limited to 145 mph in 5th gear.



However, If we can get Monty to pull 6,000rpm in 5th, we'll be pushing through the air at 147 mph.



Obviously, this needs testing

The next exciting phase is putting the theory into practice........ It's been a very interesting and informative read throughout all the various stages of development you have put Monty through..........I'm waiting for all the aerodynamic aids and weight saving to start to influence Monty's drag co-efficient to help achieve the theoritical limits....those front overriders look heavy and must create turbulance.........

Probably need a very long runway

New Ramair foam air filter fitted

From this....



To this.....



The new direct to throttle body foam airfilter deletes the induction pipe and one significant bend, it also adds an internal velocity stack. The new arrangement is now largely pulling cool air from the top bonnet louvres, and the cooler nearside engine bay area so while it's definitely not a cold air intake, it is way better than it was!

And better on many levels, with the addition of the cold air feed I've got planned out, it'll be Monty's final fully optimised induction setup.

It needs testing, but I also predict the new arrangement will give even more of the lovely 'Sporty Snorty' induction sounds Monty likes to make
