Well time to start again i think(track car)

[Grant Monkhouse]

Awesome mate.

You just can\'t beat a big rear end on a good body! Lol.

Looks weird underneath with the fuel tank gone. So much space

Dashboard looks awesome too

[turbotoaster]

this is my design for the rear end



red is fuel tank
dark orange is the chassis/boot floor
light orange is the bumper
black is the subframe
dark grey is exhaust
light grey is diffuser

the exhaust will be a 4inch bore with a 12inch diameter silencer, it will exit into the diffuser for that \'blown diffuser\' look, should hopefully keep the noise down

the diffuser will be made out of ali i think as its cheap and easy to bend to shape, plus can take the heat, i will cut the rear bumper to make space for it and the dotted line shows the venturies.

Im planning on it sticking past the rear bumper buy 3-4inches to help with seperation.

we test fitted 18x12 et15s on the rear and they fit so im gonna run 335 tyres, hopefully 99% of the time ill be power limited, not grip limited

[RobMatthews]

how much was the cleaning/powder coating on the arms/subframes?

when you planning on going single tub?

[Grant Monkhouse]

With the exhaust being under the fuel tank will it not heat it up? Obviously you can heat shield it etc but I would imagine it will still get hot?

Surely hot fuel won\'t be as good as cold fuel? Mind you, you could always run your fuel lines through a part of the water tank for your WI to take some if the heat away. I do believe Rice Racing does that?

[turbotoaster]

potentially but i will like you have insulate it from some of the heat, it maybe in the future i fit a small fin type fuel cooler but only if needed, id probably fit that next to the gearbox where the fuel lines come into the engine bay.

your right that hot fuel isnt as good as cool fuel because theres more chance of auto-ignition, i havent worked out the figures yet though at what level of temp increase becomes heavily detrimental to that yet.

My extra tank might be carrying methanol, its cheaper than buying race fuel.

I havent decided whether to chuck loads of water or meth at the problem yet, water is free and i have an ignition system that will laugh at it, plus its a bit safer

Rob - ill ring jon today and ask for you, have you tried ringing him for a price?

[RobMatthews]

no i\'ve already done mine to be honest but with a drill and wire wheel lol, just wanted to see what it cost to pay someone as its a dirty old job!

have you still got your old car there? dont suppose you still have the bonnet catch cable?

[turbotoaster]

yeh the old shell is still there, once we get to the point where the car is nearly finished ill let everyone have a free for all on all the parts as it will help me pay for this build.

i would imagine the cable will be fine, but didnt look to see if its still in the car or if its been used.

Best thing to do is ring jon if your after a load of bits as the shell, interior and wiring is pretty much complete.

[shaunwil]

Please don\'t take this the wrong way but your doing some massive work to the car and its progressing really well but have you considered the squidgy bit in the drivers seat.

Is it worth getting more instructions for such a monster car out on track. The last thing I\'d want to see is you to bin the car down to lack of experience.

[RobMatthews]

Im interested in your fuel tank, jon supply it? size etc has it a built in swirl pot etc?cost?

[turbotoaster]

yeh rob it was made by them, its quite a good idea behind the design as it means you dont have to run a seperate swirl pot and lift pump which cuts down on weight.

the only way you could get fuel surge is either running the tank down to less than 1/2litre of fuel which would be very rare or if the car flips on its roof.

the benefit of this setup is ill be able to use the minimum amount of fuel required to complete a race which again keeps the weight down.

this is basically how it works

its a 60ltr tank with a 1litre swirl pot being picked up by 2 x 044s though -8 lines, fuel cap is in the B pillar which runs to the front top left corner of the tank for filling




any questions?

[Kriss]

Where did yuo get the front wide fender? I\'m searching something like that...

[RobMatthews]

another question how do you know how much fuel is in the tank?

[Grant Monkhouse]

If it doesn\'t start, that means it\'s empty I would imagine filling it to the brim before e every race/event will be the best way to make sure you don\'t run out of fuel.

Does the fuel tank have foam inside it too to stop the fuel sloshing around? Or is it baffled?

[turbotoaster]

another question how do you know how much fuel is in the tank?

im running an ETB digidash2 that comes with a fuel level sensor so ill stick that in the tank.

since the tank is rectangular it will be pretty easy to give an accurate reading of the whats in the tank

dont think ill be running that low that it wont start......can you imagine going racing and running out of fuel, how embarrasing would that be, especially if you only had to cover quarter of a mile, hey blitz;)

You would log injector duty for one lap of where ever your racing, calculate used fuel, then times it by the amount of laps(add one extra for cooldown/warmup lap)

Im not currently sure whats inside the tank, been trying to ring jon all day but sounds like hes busy moving shop so dont want to pester him to much

[turbotoaster]

picked up new item today, since funds are limited im holding off on the big turbo until ive got the funding in place.

So i bought myself a knightsports twin pipe downpipe off a member on here.

This should help with reducing back pressure, egts and exhaust gas recirc on the compression stroke which holds off potential det and in turn increases the overall VE of the engine.

If im going to be running upwards of 20psi again on track i want to help everything as much as i can.



hopefully help with spool aswell as non-seq twins are pretty lazy
