the SSM to be turbo'd ......... has now been turbo'd!

Build thread will follow sometime soon


On first run out at NJMP last weekend, I was getting "hopping" at the rear end on the exit to (primarily right hand) corners - probably easier to watch my head move and listen to engine

See video - http://vimeo.com/39336123


Car:
302 hp ... but first event so taking it easy
1.8 with new internals + Garret disco potato turbo
Spec miata suspension and old 7" toyo RA1s (yes i know needs upgrading ...but ran out of $$$ after budget more than doubled)
Torsen diff
6 speed mazda speed gearbox


All advice appreciated??
Shocks?
Diff?
Engine??



Cheers
Steve

 

what ECU? looks like poor acceleration enrichments.


but i also wouldn't be riding on spec miata supension as well (unless they were revlaved bilsteins and a better springrate)

 

AEM v1
yeah I know - will add it to the (never ending) list after big wheels and brakes

plus forgot to say, runs on E85

 

Yeah, it does seem like it's happening on the accel out of corners. What are your afr's looking like?

Also, double check that your driveshaft is properly seated to the pinion shaft and that the u-joints are good.

When this is happening, is the shifter jumping up/down as well?
