RX7 Improved Production Racecar


Guest |114|

Recommended Posts

After the success of the Vi-PEC install into my Honda City I am now doing a RX7s1 13B bridge port racecar with Scott@Insightmotorsports

as our next test bed for developing our range or Rotary engine products,a list on the car below

Race Torque built 13B bridge port engine (for now till our own in house built engine is finished)

Phil Laird 4 throttle intake manifold (highly modified by us now)

V88 Vi-PEC using 2 EGT sensors with controller,2 knock sensors,Tech-Edge dual lamda controller & gearcut strain gauge

Vi-PEC 4 channel CDI with Mercury Coils

So far we have made great part throttle gains with the Vi-PEC over the old ECU setup and it has allowed us to play more with intake manifold design and the engine sounds very different now,

again I cannot thank Scott from Insight Motorsports enough for his knowledge & input and to Ray Hall for the late night e-mails with great tech support,I will keep the thread updated as we

get more involved with developments.

Regards Dave

More on this setup soon after months of playing around we will finally be back on the dyno within the next couple of days to get the

engine ready for a run in the IPRA support race for the Bathurst 12hr race meeting early next month in our 2nd team car.

Cars 119 and 4 where not in our class and running slicks we run on a control R compound tire

We cant thank Vi-PEC and Insight Motorsports enough the car did not miss a beat all weekend we just need to sort out a few chassis setup issues and then we will

be able to use the power our engine is making.
