Kermit II (K-II) Triple rotor rebuild project

I love this build.

Some one has been a busy boy! I love the exhaust exits!
Just on my rad brackets too at the mo!
Certainly will have to make a trip over to you in the not too distant.. Just a bit busy at present.
Keep ploughing on!

Thanks fella, yours and others comments keep spurring me on !

Hi Leeroy, a cuppa is always available when you pop over.

The rest of the exhaust will be completed on Monday and I will order another intercooler as we need a specific
shape and size for what we\'re trying to achieve.

Good luck with the brackets, they\'re awkward buggers to make as you need 10 pairs of hands !!  

[leeroy_25]

Cheers.. I am less concerned with the brackets and more worried what I am putting where! Really cannot decide. I have 2 intercoolers waiting to be cut up and I cannot bring myself to do it! Will have to take the plunge soon or go with a different setup that means no cutting!
You are lucky having so much more room to play with on a race car..

You say that but I\'ve got to put all the coolers somewhere, heat is a racers devil.

1. Big Intercooler
2. Big Radiator
3. TWO big engine oil coolers
4. Big Gearbox cooler
5. Fuel cooler.

And I\'m even toying with a Diff cooler if I can work a way of doing it !!  hehe

Bit of a \'sitement\' nightmare to say the least !!   lol

[leeroy_25]

Fuel cooler?! Didn\'t know there was such a thing!? Are u planning on racing in the dessert or something!? Looking forward to seeing your cooler setup!

[Grant Monkhouse]

Fuel coolers are necessary as engine bay heat can heat up the fuel in the lines and returns to the tanks, fuel coolers keep the temp consistent and low so that everything going into your engine is consistent. Makes things easier to tune etc,

Tbh think that might be a bit of a Myth, but would be interested to see.

We\'ve measured the fuel temps on K-I and they do rise significantly on full chat on track, defo needed.

Fair enough, But to me that sounds like your not using Insulated Fuel pipes? shifting the amount of fuel you will be at 40-50psi it\'s going to be moving quite fast through the pipes. On our Rally car with a 1lt swirl pot the fuel temp did creep up when cruising off boost but at full chat it was pulling 90% fresh fuel from the tank so stayed about ambient temp.

Anyway be interesting to see the results.

Thats good info, we will have to recheck the temps again on K-II as its
a dash 10 fuel line with dash 8 rails now so the flow will be slightly slower....
.... we think !!   lol

rotarys love to heat up the fuel. we found this with the drag car on the dyno and on our t/a build, we were not able to touch the swirlpot after 5-10 laps of donnington

a few of the timeattack rotaries in jp run a fuel cooler in the numberplate recess

We\'re thinking of running a small vent under the car when we flat floor it and run ducting into the new fuel tank area for the cooler
AND keep the whole assembly cool.

or just make it a non return system

PMSL !!  no no no !!  :Giggle
