Alright chaps, my project from 2004 finally almost (!) finished and hopefully will be going for an MOT in the next few days!
Spec in my signature, but in summary a 5gze block with HKS stroker crank and OS pistons, levin block and smallport head, TRD OS valves, HKS cams and HG. Block bored out and with stroker think it's about 1.7.
HKS supercharger pulley and HKS T3 turbo and partial HKS twincharger kit.
1.6 bar of boost
301bhp at the wheels
251 lb/ft
At that point the breathing got a little restrictive. So there's room for more. C16 would also probably generate about 50bhp more I'm told! However I am stopping for now as I'd like to drive the car at some point, LOL.
Bits of the story here

Of course the figures aren't the whole story. The graph is the interesting thing, no lag! I'll post it up when I've got a chance.

Re: The twincharger lives!
I feel as if there has been a rip in the space time continuum!
Well done Toni, only took 10 years lol, looking forward to seeing it

Re: The twincharger lives!
Hey up Paul, do you have an idea of what transmission losses an E51 has? Engine must be making 40 or so over the 'at wheel' figures possibly?
If I knew then what I knew now I'd have never started it, LOL!

Re: The twincharger lives!
A loss of at least 50bhp I would say.
Remember when we put all our SC's on the rollers, Toni (back in the dark ages) and there was about a 60bhp transmission loss.

Re: The twincharger lives!
That's what I was thinking, so engine is doing quite well at 350bhp ish at 1.6 bar really. Pleased with it, particularly as it is capable of more....

Re: The twincharger lives!
Yep i'd agree with around 50bhp loss, that's pretty impressive, do you have any dyno sheets yet? I'd love to see how the torque curve compares to a 2gr setup, i bet there isn't much in it.
Re: The twincharger lives!
Top stuff Toni.
Trying not to reason with myself that turbo+standalone is more interesting than sticking with the supercharger!
Looking forward to some Dyno vids!

Re: The twincharger lives!
Bit Heath Robinson but pic of dyno plots...blue line is most recent.
Pink we were experimenting when to bring in the sc...the answer is straight away! Gives 180lbft from the off then!

Very nice - thanks for posting it up!
What was done to change the torque curve soo much between runs?

Re: The twincharger lives!
The pink line is a 'before' we adapted the bypass of the SC, but also in the blue run the SC was bought in a lot earlier.

glol!
Awesome, so glad for you as well

Re: The twincharger lives!
Very nice, you aren't that far off 2gr levels of torque there, i have 200lbs.ft from the off and max out at 290lbs.ft
I'd say it's been well worth the wait

Re: The twincharger lives!
Since I'm half the literage of a 2GR I'd say that was impressive.
On C16 or with improved breathing it could probably do more, but I kind of feel that's enough for now!

Re: The twincharger lives!
Very happy for you Toni.
I wanted to wait about on Tuesday to catch up and have a look round it with you and even maybe beg a little ride round the yard but I had to get back.
Glad it's all you hoped and I'm sure it's worth all the time and patience (not to mention funds) invested. Looking forward to seeing it at Classics On The Common.

Re: The twincharger lives!
Great news Toni
Could something similar be acheived based on a 7A-FE block rather than using the uber rare HKS stroker kit

Seriously don't even think about it. Completely mental idea as I told Toni some 9 years ago!

Fantastic news Toni, it's been a long time coming! I bet you can't wait to get it out for a drive now?!
