On Sunday, Garage Whifbitz attended the MKIVsupra.net Supra dyno day at SRR, as we needed to check out the current performance of the cars and we also get a chance to catch up with some fellow mkiv supra owners.
Back in July we’d seen 602HP/515lbft @1.4bar but we had a boost leak so couldn’t hold more than that.
This time round we saw 652HP/550lbft @ 1.3bar, again with a boost leak.
We still need to find the leak, but after a full engine refresh and a new inlet manifold it should be relatively easy to find it.
This is a great improvement, and does show to some extent that the new inlet has increased power.
Concensus indicated that we should have been able to get 700HP had the boost held.
… time to find the boost leak.
