There were guys there running 11's with mile per hour around the 125 mark, just had 60 footers of 1.9 and lower.

My wheels spinning was probably another factor limiting the top speed Dean

You can run 11's with 118mph in a BA/F, but I wasn't eluding to the fact you weren't going to run 11's mate. Was just saying the mph was low for 400rwkw.

Wheelspin actually nets a bigger trap speed, albeit a slower et. Has something to do with getting the weight of the car moving in a shorter distance, as well as increasing the distance travelled so to speak. Your wheels actually rotate extra revolutions when slightly or violently spinning don't forget...

Not having a go, just curious as to why it is slower now than it was last time out even though power is higher. Blocked cat would explain it, but I would have thought Ernie would pick up on that whilst tuning & offer advice as to what your options were, especially since he knew you wanted to race it. That was why I was kind of leaning toward the cat not being melted/shagged.

Yeh all good mate

He did pick up on in and said that it would be a restriction, it was because of what he found when tuning that it was dialled back to 390rwkw. I'm not sure what else it could be, maybe valve springs starting to float.

What Power did it make on pump fuel Aiden?

Made 403rwkw then we dialled it back to 393rwkw Im pretty sure, will check the dyno sheets when home

123mph suggests 340rwkw, and as I said that mph figure will be inflated due to wheelspin. Better sort that cat soon as it's really robbing you of power/speed/time.
