Hey Mish im putting an Mx5 Gbox on the back of my FE3N (Big block BP) Based on the the FE diesel. Can i get some pictures of your set up for the gearbox? Cant seem to get it to fit without cutting the original mounts out of the tunnel
 
Cheers

So today i thought id try out the straight line stuff, went to a not so local test and tune day out at Heathcote Raceway.
 
The day was very busy and with racing only run for 4 hours i only managed to just get 4 runs in,
best of the day was a 12.86 @116.3mph 
my 60 ft times were all horrible best being a 2.20sec
 
All in all it was a successful day, i now know what i need to do to improve the car if i wish to and i was able to not break anything which was good considering it was a 250km round trip.
 

 
 
 
 

Good stuff. That's a kick ass time and to be expected from your power output. What changes would you make to the car?

Was a little disapointed with the times to be honest, thought it had enough in it for a low 12 pass but wasnt ment to be. 
The main thing i will be doing is installing a line lock or a brake hold system so that i can get a decent burnout going, was really stuggling with that side of things due to lack of experience and too much of a well set up brake bias. I think getting the slicks hotter would drop my 60ft times a bit

Burnout does make a big difference. Apart from getting slicks hot you may have to play around with tyre pressures to work out what setting works best, slicks can bog down with wrong pressure. Len

My MK1 did a 2.2sec 60ft with cold street radials, tyre pressure 30psi. Standard diff & clutch. 
I imagine launches are a totally different world with boost

Yeah had a bit of trouble finding the spot where it wouldnt bog down once i dropped the clutch but also not too higher rpm to distroy the box. 

I had the same bogging issue with the Webers. They don't respond well when going from idle to full open throttle. Took me about 5 runs to figure it out, just needed to have my revs up on the line, around 2500rpm

another weekend another 350km round trip, this time for the annual RSOCvic motorkhana.
 

 

 
aside from a vac blanking plug coming off and the car idling @3000rpm for a second the day was faultless. 
 
still not sure how this gearbox is holding its **** together....
