Went to the Pod yesterday with the slicks swopped for 888s, so sort of street tyre, and ran a best of 11.9/114 and 1.7 60ft. Well pleased. *Cloud 9*


Excellent mate, well done
Once Simon stops playing about on low boost he should see some 11s runs too *happy**happy*

Yes i moved to the darkside *happy*

Latest dyno results gave 215 bhp, then 277 bhp with NOS, and 288 lbf. ft. torque. Power held up well beyond 6500 although peak was 6100. I'm using an Avonbar PH1 cam supplied by Ian Hargreaves and although it loses some low speed grunt it does exactly what want on the strip, running between 4 and 7000 revs

well done steve ...what boost ?

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

I have started posting on Instagram also my name on there is turbomk1mini

Nothing is impossible it just costs more and takes longer.

Boost was around 20/21 psi. When I tried a bit more the dump valve started leaking, now have a stronger spring on the way. Hopefully with that installed I can tweak the boost to about 23 and hit the magic 300 bhp. Don't think the transmission will take any more.

Have you considered not running a dump valve steve ?

The theory being , if you change gear fast enough the back flow is not enough to kill the compressor , and the wheel speed on the turbo will not drop ,and so you get a big jump in torque on the next gear ...

Interesting theory Robert, could it damage the turbo if I shift too slowly? My shifting is not the best, combination of old age and excess of mechanical sympathy.. *crying*

Practice your gearchanging Steve !!
Robert, I was past your house on Sunday on my way to Pinnocks farm to view an MG Midget but was not sure if you were here or across the pond

So back to the Pod yesterday, managed a new PB 11.85 @ 114.7, off a 1.71 60 ft. Car felt good, but there is more to come, as i need to launch the car better. I moved the intake temp sensor to the engine side of the NOS injector, previously I saw 60C , now 20C, significant cooling effect.

I bet it was a little toasty in the nomex! Great result, congratulations.

Thanks guys, and yes it was a little toasty at times. I picked up a high speed misfire which I suspect was heat related.

So a stronger dump valve spring resulted in more power, and I practiced gear changing as instructed. Went back to the Pod yesterday and ran 11.78 at 115.3, so well pleased with that. *Cloud 9*
