BTW, I was talking to Ian (Danger7) at the National, and he said that quite a few Euro VXT cars are running upto 360 to 380 BHP on OEM internals (for many thousands of miles safely). Food for thought...

All with water/meth injection Nev I presume?

I don't really know as he didn't mention it, but water/methanol would only be needed to keep the IATs down, which is not really an genuine issue for road driving with the Pro-alloy system (unless you drive in properly hot ambient air like 35+ degrees).

 

What I was more surprised about was the level of power (and presumably torque) being so high on standard internals.

its not much, only about 320 torque @6000 , its the high rpm that hurts the conrods at an exponential increase in risk

wtf am i going to with this car once the ta is over?? i hate it like a bout of gout but when its been right its been awesome,sell it,break it,store it,do it again? anyone know of a race series me and george could use it in?

[jameso]

Detune it a bit so it's more reliable and will run all day, and race in a bhp/tonne classified series like 5oc? Then you aren't worried about runnin max power all the time cos you are out powered in TA (as it'll be a level playing field)

lbft be the killer of rods tho not the bhp surely

Yes you are right, lb/ft and RPM are the killers IMO, but to get 360 BHP they must be making more torque + revs presumably, but by how much I don't know.

Not worth breaking it so get that thought out of your head, your stuck with it! You have butchered both clams and no ones going to want an engine thats been in your car. The very least you can do is loads of trackdays in it next year, id love to do one a month next year in all weathers.

Something like what 5oc is doing would be great. We will happily detune the car but need to do something with around 250bhp per tonne. Even if we made the car standard we would have to add a fair bit of weight to meet the 175bhp per tonne limit.

 

IF we end up doing anything it needs to be something relatively CHEAP and that we can share the driving.

Rallying !!

[siztenboots]

team trophy , or trackday trophy. Its not a point scoring championship so no harm if you miss a round, just collect winners trophy for the ones you fancy.

[GeorgeBC]

Trackday trophy is limited to 175bhp per tonne and team trophy is 200bhp per tonne. Both mean adding weight but team trophy wouldn't be so bad in a standard turbo with the weight of cage and fire extinguisher.

Can't you massively under map it George? That way you will have bags of cooling and loads of reliability? Also... Adding weight to the front of a vx is maybe a good thing anyway (distribution wise)

weight includes the driver

Wouldn't cost much to make the car standard again.

 

Were not sure were defo doing anything yet it would be expensive and i still want to keep and track my own car next year. Just looking at options and we still have two TA rounds left yet.

Didn't realise that. With Darrons gut we could make the 175bhp per tonne then

[siztenboots]

and its as measured at the hubs, so thats about 12-13% lower 

[siztenboots]

so you would end up with a map something like

Comedy!

[siztenboots]

you have to run with a 36mm restrictor  

[siztenboots]

the standard throttle body top hat is about 40mm
