Just for the record, I contacted DHM about co-developing the EFR kit and pretty sure it was the first BT kit started by them
But, it ended up with far more lag than expected and other issues I did not care for so decided to go GTX but I have not been able to work on the car for months though the swap is all paid for, I hope to get started on it in two weeks or so at my daughters house in Scottsdale.
At the time we discussed the change I was looking for a bit more than 300WHP, more like 320, on pump gas and it seemed like the GT2554 was not going to be quite big enough though it has shown great results so I might go right to it instead for the broader power band more suited for my needs.
Since my focus is on road race tracks big numbers and big lag are not the best way to go though I will post some pretty serious lap times that will be hard to beat
My best so far is an unofficial 5 seconds faster than the spec Miata record at MMP on the outer loop which is 3.048 miles long when I had just 220WHP, that is very quick to say the least.
I most highly respect the drag race oriented driver and car though, of course, love to see the numbers already attained and lower to come
