Better economy than my ht18 and std pump tooThe other weekend i tried a few different turbo configurations only to go backwards.
Still all based on the UFI TD05M tubine wheel.
Yesterday, I was machining up a couple of different turbine housings to try some different turbine wheels, when it occurred to me that I hadn't tried our 23L compressor wheel yet.
The TD05M 23L is what we supply to guys wanting 300hp and above.
I had been using the older 23C compressor wheel.
Compressor wheels are the same size, so they interchange easily enough. The 23L is just the latest version with a different configuration to the compressor wheel.
I really wasn't expecting to much change, so just strapped it on the dyno, didn't hook up the boost or AFR cause, well, it was hot, been a long day and I was in a hurry to go jump in the pool.
To my surprise, it made 1115nm and 276rwkw, woo hoo.
Just some points of interest on the dyno sheet that are hard to pick up by looking at it.
175rwkw @ 1874rpm
200rwkw @ 1955rpm
223.8rwkw @ 2038rpm (300hp)
250rwkw @ 2160rpm
275rwkw @ 2476rpm.
1000nm from 1972rpm to 2615rpm.
still has 265rwk @ 3200rpm, this is where some fuel cut starts to take place in the pump.
Peak boost by my gauge was 43psi
Pre turbo pyro hit a max of 804degC roughly. ( its a bit hard to keep a eye on all the things going on)
Economy wise, it used 87lt to do 643km running to and from work and a few errands through the day, no dyno time in that.
To be honest, I don't think I can squeeze much more out of it.
I will try and find my spare high ratio rockers again today that are somewhere, and if I find them, I will replace the broken one, and have another crack and see what it does.
I am pretty happy with where it is at at the minute, and a normal person would just leave it be and enjoy it.
But, lol, i just cant leave things alone.
