It’s rather nippy but to be fair not exactly great weather to not die when testing. Will give it a proper drive when it’s dry.

I bet the drive back will be fun!

 

[Steve Swan]

OOOOOft. Should go like shot through a Goose..

I’ve got a Dragy to test and that road would be ideal.

 

[Adey]

lol I've borrowed one also, its my road of choice. Just need to find some time between work and kids to get over there. Quiet enough to fully stop on a lot of the time

Some observations when comparing yesterday’s graph to last years.

Changes were bigger/fatter intercooler, new 60mm waste gate vented externally. Large K&N air filter. Just a few additions in the way of 2 x EGT probes reading in the ECU and added AFRs into the ECU too.

Previously at 5800 I was at 400hp now I’m at 500hp. Even at 5000rpm I’m up 40hp on previous set up.

Roughly 800rpm better spool give or take, 400lbft is from 5000 now, was from 5750 before.

500bhp used to be at 6500, now it’s about 5800

I now hit 550bhp about 900rpm sooner, used to be 7000 on the dot, now about 6100

At 8250 I’ve gained about 30bhp as there’s almost no drop now like there was before.

At 5500 & 6200 I’ve gained 80lbft

 

[Adey]

thats some heafty gains in delivery

Christ, with that much power you'll be peeling the paint back when you mash the go pedal

Has the Twingo met it's match....?

 

[Adey]

The rx7 isn't a match, it will just bring the slaughter!!!!

New refurbished box fitted plus fresh diff oil all sorted over these last few days.

Also a few little tweaks adding some additional engine protection features in the ECU, we are hoping to get a few more dialled in on the rollers later this week.

I decided to be a child and legally transfer over my GAP You number plate.

On the subject of Go Pros I need to buy a new one. Which one of you got ?

Mines old buddy, gopro hero 4+ and my phone for all my stuff. Think the gopro still does 4k but has no stabilisation built in but is fine when mounted, the phone will do 4k and more.

Hmm ok, I’ll see what’s on eBay at the mo.

 

[Mark Davis]

Oh I forgot, I acquired another HX50 to eventually fit a larger compressor wheel.

because 600bhp just isnt enough

I’m hopefully going to SRD rollers Friday as after the 608hp run the dyno couldn’t hold it, kept spinning so hopefully we are making a bit more, downside is of course that SRDs rollers will likely read differently to Jamsport.
