does any body know how fast you would be going if the ogange needle on the 100 mph bar graph speedo disapears compleatly. id just gotten my car back from having it dynoed ,they also ecalibated
the speedo , then i hit the road doing the speed limited 110kph ,she was puring thanks to my now regular workshop, so i decided to see how she went curious on how she whent as the engine is
now nearly broken in and to hear the second barels if the deloghtoes it took nearly no time to do and she wanted more, i cant wait to get the hp figure as they assure me its in the post cant
wait to find out though. has any one got any predictions . its an a15 with all the right machine work 10/1 compression ,lumpy cam (ive got the specs some were) twin deloghtoes , huricane
extractors ,1.75 staight through exhast, and seems to thash xr6s (thats all ive draged so far)
any responce to this will be appreciated . what do you think my qurter mile will be

A healthy A15 should have 140+hp with that power should run 14s easy.
Talking about speed Can someone work out what speed my datsun has done it was reving to 6400rpm in 5th gear 0.83 overdrive it has 195/60/14 tyres and a 4.625:1 diff ratio All I know is
the speedo was tapping back on the 0 for quite a while and the road was nearly a blur it had more in it but revs where a bit on the high side. Ill put the 3.3 in it and take it for a
run out the road

Yep..My 1200 hit the 0 on the coupe dash. ~150mph?
That was without a turbo..instead a nice big hill on the way to Canberra. The speed calc relies heavily on measuring the diameter of the rear wheel, and then estimating how
much its diameter has expanded at that speed. But we could guess.
..How's the rebuild going?

Nearly complete just have to assemble bottom end and receive new copper head gasket bolt it together ang have it tuned ect.It has a 350hp roller bearing turbo now :) if you
know anyone after a 290hp roller bearing turbo to suit CA18 let me know.
cheers Andrew

"reving to 6400rpm in 5th gear 0.83 overdrive it has 195/60/14 tyres and a 4.625:1 diff ratio "

That works out to 113MPH. Lots faster than a stock 1200!

Dattodude : FYI 150MPH would be 7100RPM in 5th w/ 195/60/14's, a 3.9:1 diff and .83 OD. It would also require somwhere in the neighborhood of 270HP or more. It's also
require some pretty huge gonads!!

Hi Andrew,

How much do you want for the turbo?
When does it start to make power?

Justin

It was a BIG hill, and if you know 1200 speedos, it was right around at 0. No kidding. If you extrapolate numbers on the dial it would read 160mph, I took 10 off for error, it could be
20 less. I was running 205/55, and I have had my engine up to 7000 with 3.9 .83od. As for the gonads, I think youth alone got me there. ps. I've also had a stock A12 up to 6600 in 4th :
) valves bouncing all over the place...

Well either my revs or something is out as I run 113mph or 182kmh over the quarter mile it was going a lot faster than that Maybe the tacho is out it felt to me that it was
doing over 200kmh I have a 3.3 diff what sort of speed would it be doing with same revs with that diff??

It starts to make power at 2500rpm it actually better response than stock T25 turbo but will keep going running 15psi it produced 225hp at rears behind a very basic modified
CA18Im asking $900 it cost $1600 less than 12 months ago.Its in excellent condition

I've gotten my 1200 up to 6,900 rpm in 5th gear (B210 5 speed), with 3.9 rearend, and 175/50-13's. I think the tranny ratio is .82 in this tranny. That had the speedo back to 0 again.
That was a lot of fun, but I need bigger tires on back to correct the speedo. I calculated this out to around 135mph, which is fast enough to set a record at the Bonneville Salt Flats
in the 1200's class.
