Peripheral ports

[hayden]

Best of luck from me too. But as far as I can see all you have is an unfinished RX-4 shell and no engine??? Be good to see Haywards make it into the 10s though. We need to take it to the fast piston boys as there numbers are increasing

[hayden]

i quite frankly couldn\'t give a rats ass which one of the members on here manages a 10 second pass and who is that 0.1 second slower.

then this is not the thread for you. try the one where the guy makes a scoop out of a box :Giggle

To go 10 seconds in an rx4 you wont need as much power as what an FD requires to make it go 10 seconds due to weight. Therefore PP ports unecessary, by my reckoning 400-430rwhp will be enough so a decent street port, turbo like a T78,T04Z,GT40** at 1.2 BAR will do the trick.
Grant will be a welcome addition to the drag pits, you seem have your head screwed on when I spoke to you at Pod.

there doesnt seem all that much in it for weight
 
rx4 1,188kg
fd   1,282kg
 
but bear in mind what you gotta spend upgrading everything on a 4 to cope with 400+ horsepowers
 
rx3 at 884kg would be better

I would think you can take more out of a rx4 than a FD if you really wanted to

Everyone loves a $marta$$ :Giggle
 
Such a friendly thread - still I have been learning - it\'s all good

[rbs14a]

I was at Carls today, discussing my engine and drag racing of all things. So if you wait a little while and let me learn to drive up the strip properly I will be out racing you guys.

My aim is for a 10 second pass and to go off the clock of the rx4 which goes to 130mph.

Sounds like some healthy competition for you there blitz :Party

lol...............one day Rob, one day,maybe :rollin:Tongue1;):3gears-rh:Thumbs-up

Abso-mutton-lutely. I would LOVE to see an RX4 make a 10sec pass in this country.
Best of luck with that.

I admire Grants enthusiasm, but there will be no 10 second runs off the trailer.

Engine: If it makes the power, and holds together - then it will allow the things mentioned below to run good times. Anyone can go fast in gear, you need to hone the 60ft time and time between gear changes, that is where the fast ETs come.

Tyres: How much can you fit in the stock arch and how much you are prepared to spend?

Driveline: Will it cope with full bore launches - are you running a spool or LSD?

Suspension: Lift the front to plant the back, means running asymmetric shocks, but does wonders for weight transfer on launch.

Gearbox: Any 10 second car can easily run rubbish times with a slow gearbox/shifting - rotaries synchro have it hard as you are revving so high on the change.
- If times are what you are really after, go an auto/transbrake with hi stall converter (3800) 1 step larger turbo and 50 shot of gas to get her up on boost before launch - you\'ll slingshot outa the hole!

Track prep - Santapod is not WSID (NSW) or Willowbank (QLD) and I do feel for the guys here as the times would be far better on a better track.

If you compromise it to run on the street, you reduce the ability to smack down good times at the track. A genuine 10 second (UK) street car would be a real treat but needs a lot of time and cash - the guys who have done it and are doing it now will tell you all about it.  

Way off topic I know....

you could be right kiwimazda. but you would need to add a heavy diff and turbo engine. not forgetting the fd carries a lot more equipment (interior, power steer, etc) from factory than the 4 does

[kiwimazda]

The diff is unsprung weight. The body and chassis is where ir needs to be lost. Weight moves to the rear under acceleration but you dont want to much of that.
Gearing in the diff and box are just as important as the engine. You can have all the horses in the world but you still need the delivery

True about syncros on FD boxes, been sufferring the second gear change in the last three rounds, still manage to do 10s , all the rx7s in the street class are street driven, some doing 10s , some doing 9s. It does take money though and practice .

Can you run a 10 off the trailer?, maybe not on the first run but I reckon you can do it on the same day after a few runs with enough planning and prep.
Obviously with the experiance I have with FDs, I could build a FD from scratch and have it run 10s on its first outing if I was driving.

[Nik da Greek]

Doesn\'t Rob run 9s in a car with a tax disc and everything?

[BlitzBoy]

yes thats what I said in my post Nik, stay awake hahahahahah James also in the 9s drives his to and from the strip when he has not fooked the gearbox LOL
