General Green HGT

General Green HGT

I am a bit worried about Friday. Not reliability or anything daft. If I like the car on track and recognise the potential. I might be tempted to make a few improvements. ;)
 
Unlike my Bravo you can still get bits for the Punto. Even though the ECU is uncrackable and if you run a piggy back it works it out.

Brakes, wheels, tyres, suspension, bracing and other chassis tuning parts. Such a shame it's limited to filters and exhausts tuning wise.

Still the Alfa twinsprak has the same exhaust manifold gasket as the 1.9 JTD so a manifold, proper turbo and the standard MaF, ECU and injectors are good for up to 220bhp. ;)
 


I experimented with camera positioning during my last shift. :devil:

I won't be going very quick in the car Friday so I may as well get some good shots of being overtaken. :slayer:
 
I know how serious people take track day prep' to today has been a monumental effort getting the car perfect.

Nah, not really I changed the oil, filter and topped the washer bottle up. ;)
 
Well...

...surprisingly well. The conditions were initially crap but that suited the HGT pretty well. Nimble, good tyres and enough power to put down without issues we found ourselves keeping up with and pestering better focused stuff on track.

I don't know about times as yet (I thought it would be a good idea to film five minutes at a time instead of three so there would be less cut lines in the final clip but transferring from VLC to MP4 via Race Render is taking hours.

I had fun, we raised £2,500 for Macmillan Cancer Support and the HGT certainly has potential. Not much room for improvement without doing something drastic about the engine management.

The gearbox got noisier throughout the day and the exhaust split on a speed ramp when I got my lunch but mechanically was well as well as could be expected. :slayer:
 
Back to life. Back to reality.

The reality for me is to get to Blyton Park and back I have driven on the A17

This time of year that road is either being dug up for no apparent reason, covered a freshly ploughed mud or both. My poor car looks like I have done a forest rally rather than a track day.

Back to normal with a little help from the local car wash (I could not be arsed to faff about washing my car in the snowfall again).

I have topped the gearbox oil up and even though I can not replicate the conditions on track I can confirm she's a lot quieter.

Best case scenario the top up has worked and I'll do a full change in a couple of hundred miles to see how much damage is done. Worst case I need a new gearbox, but so long as Punto HGT ones are holding a premium the Alfa lineage of the engine block should mean I can use a 145, 146, 147, 155, 156, 166 one if needs be. ;)
 
Very good update thanks. Looks like you had an amazing day and the Punto coped well. You did really well with your fundraising too I’m looking forward to experiencing this for myself
 
Oh crap!

My best time when my Bravo was standard apart from brake pads and tyres was 1.41.3

My best time with a standard HGT apart from tyres (in the damp and with a noisy gearbox) was 1.29.6

:bang:

My best overall time in the Bravo was 1.24.8

With a modest budget my Bravo improved dramatically I know this will not be the case this time as removing the AC from the Punto and adding a better filter/exhaust would be effective until the ECU learns, adapts and automatically restores factory settings.

I've done a bit of a write up in the description. :)
 
I'm thinking with the block being the same as the Alfa 1.8 Twinspark a 2.0 block with the HGT head could work. The section in the Guy Croft forum (I posted earlier) is more than discouraging.

My Punto and I were consistently hovering around the 1.33-1.34 mark and 1.29.6 was a bit of a fluke while chasing a Megane 225 RS (making 260bhp).

Do I spend money improving the HGT or stick to the plan and build something to beat it?

:devil:
