longativity of 200+rwkw

**go_the_datt** · 07-04-2006, 06:34 PM

but i wish to drive the car on wednesday nights at WSID. isnt it a stipulation that it must have rego to drive there for the street meets? ill go check now
like i said it doesnt bother me if i cant drive it. it is only going to be a qauter queen but i thought itd be fun.
maybe i will abandon the project for something else....
cheers
edit. if the car doesnt have rego it can just have a ANDRA log book in lew of rego...

nahh, do it anyway... it will be fun!
get video of each run in case it blows up

I know a guy with a 300rwkw 4agte (might be more by now

) which i think is road registered. As stated, it is possible to build this sort of engine but the costs escalate VERY quickly.

My build is nowhere near this sort of power but will eventually cost me around $16-18k for engine/driveline/brakes/support systems. I hope to crack around 200-220atw with a maximum redline of 8.5k. This is probably the limit of a "comfortable" road 4agte but i'll have to wait and see about that as well.

Go the DAT:

Yeah it can be done TRUST ME!!!!!!!!!!

Im making near on 300rwkw with std cams on unleaded race fuel. It drives a treat.
My goal is to reach 300rwkw ( people told me i couldnt do it

LOL)with std cams then change to so HKS items and make some real power!!

The biggest prob you will face when making over 300rwkw is the block. They split bores above this power level and the remedy is to fill em with grout. But this means you cant run coolant in the block and hence drive for extended periods of time.

The other prob is breaking gudgeons.

Can you run Methanol in place of using coolant? I don't know a lot about it, but I know it cools things down pretty damn well....

Methanol will cool things down but its more to do with the inlet temp/ fuel side of things. It wont do anthing towards cooling the block on long drives.

I have wondered if getting a custom crank girdle made would help strengthen the block but my mate in Las Vegas says it is the thickness of the bores that has issues with the compression needed to make big power! ( they just cant handle it )

why bother, even teh p00 7m can do 300rwkw when spending like $4000 on it..
why bother with a 4a ?

**mullett** · 08-04-2006, 11:40 AM

Not really relevant...we covered that earlier, he wants to stay with a 1600cc motor. I think the common consensus is that his power expectations are stratospheric, but nothing's impossible. Just on a sidethought, a B16A might be an option if you're going to spend that much money. Heaps of work to get it in, but I think they're capable of supporting a fair bit of boosted power (I know someone got 240hp out of an NA one (!) But again, for sake of driving in once or twice a year, just drop a bigger engine in it and de-rego, the money you'll save on the motor build will build you a tough street car. Just out of curiosity, how much money were you planning on throwing around?

can i suggest you read read for real-world discussion about 4agte - flynnSX's 'rolla:
members ride thread

was aimed at ~230rwkw - streetable, drivable and dragable.

**General_Bupkiss** · 08-04-2006, 02:06 PM

Ok so we have established that 350kwatw is probebly possible. so i say go for it. as for the rego'ed part of it. i wouldn't drive it on the street, but I have no doubt you could get it street rego'ed. have a look at all those 9 and even 8 sec rotories that turn up to the wednesday night drags on traliers and leave on traliers they would never see the open road, yet they are registed, how, cause they have connections. It is not hard, my mate has managed to keep his unrunning 1200 coupe registed for about 2 and a half years. It is not legal but doable.

**mullett** · 08-04-2006, 02:22 PM

Precisely. If you don't road drive it, it never gets a sticker, you just keep paying the rego, everyone's happy...

**Joshstix** · 08-04-2006, 07:50 PM

But why would you keep on paying rego for a car that you are never going to use the registration on?

The government takes enough money without you choosing to donate more like that. Get the car tech inspected by ANDRA and you can still run it at street meets.

What he said....

well im offering my services to do the pink slips on said car if he so wishes as i get to take it for a drive to do the brake test

I'll attempt to answer your original question - you can make a car that will live happy at 200rwkw - how long it will last is a question like "how long is a piece of string?" HP doesn't kill engines, rpm kills engines (within limits - cylinder pressure being too high will hurt things like lifting heads etc).

But if it doesn't live at it's first excursion to the 350rwkw power level, then it's longevity at 200rwkw will be easily worked out by examining the power graph and making an guesstimation at how long it took to pull through that zone.. if you catch my drift

No it is not a requirement to have street rego at WSID street meets. The car must be teched (ie have a log book) if it isn't rego'd and you are not allowed (at least for the time being) to run sub 9.0s.
