This is just an information update for any of you guys that are running the Richwood supercharger manifold.
I recently found out from one of the Soarer Club members here in Aus that the injectors dont sit far enough down into the ports in the manifold, they are approx 4-5mm to high and the spray from the injectors hits the wall of manifold causing the fuel to turn into droplets rather than misting.
Mine has never run very well at lower speeds when there is not a high demand, with greater demand for fuel it didnt seem to be a problem.
When mine was tuned, the tuner said he could not get the fuel trim any better at the lower revs and idle was always a minor problem.
We didnt know what the problem was and now hope that this will improve things.
It does seem to drive a bit smoother and does sound a lot better out the exhaust,
bit hard to explain that one except to say it sounds like it was choking when driving at normal city speeds, just sounds a lot smoother.
It has been 18 months since I ran short on funds for this, so I have driving as is with at the last tune was 310 rwhp.
In the next few months I am getting a good quality water/meth kit from the US, and am going to set up a good oil catch can system.
Then it is down to a tuner in Melbourne who knows the Wolf V500 ecu that I am using and also knows the Toyota product.
The last Soarer he tuned, with a set up similar to mine produced 398 rwhp.
His Soarer with a built motor came up with just over 600rwhp and the gearbox didnt like it much, so the gearbox now has to be made stronger, he is aiming for 670 plus.
Apart from tuning issues, I have had no real dramas with the Whipple set up and will be very happy to get some decent results finally.
Here are a couple or pics of the strip down and rebuild.
