David Buschur's RS/BADBISH 2010 build
Thanks guys. Luckily for me, my drive on this car hasn't ended yet. Generally when it does I sell the project and I don't want to sell this one. There's more to come but it is getting more and more difficult to keep improving. Few ideas left in my head. This year might be the year I finally install my electric power steering that's been on my desk for a few years
I actually drank coffee/tea/redbull just to stay awake and finish reading all 12 pages! Amazing testing... does any one still have reasons not to trust the work & craftsmanship @ BR? I dont think so!
Keep it up guys!
Keep it up guys!
I totally took your advice on the braided lines and oetiker clamps. The last thing I want after getting my car back together is a vacuum leak. I think it's a great idea for anyone that drives their car everyday.
More work ahead of us. It just never ends. I am going to spend some time on VWJeff's car first and try to finish it up then go back to testing on mine. So much for not doing much testing on my own car this year. The line up is growing again.....
Here is some video action of the RS since it's been put back together.
Hope you guys enjoy it.
Thanks for putting these together Jarrod, great work as usual.

OK, I hope to see Ted and R/T back in this thread.
First off let me say, there isn't much more that aggravates me than telling someone something, having them call around, get a different answer and then tell me what someone else said, so don't be offended by my "calling around".
One place I've found to give me reliable information is Kinsler Fuel Injection, they haven't failed me yet. I spoke to their engineer there about the pulses in the fuel system. While I seem stubborn at times, I get to sleeping on something and then usually open my mind up a bit. So I got curious about this.
Anyway, I just hung up with the engineer and I have some information I feel safe with for my application.
He asked HP levels/rpm/fuel pressure etc. Then gave me a formula to work with.
He told me to take the base fuel pressure, add in the highest increase to it, divide the base+increase by the base and then take the square root. This would give me the effect on the flow in percent.
So 40 psi base + 2.5 psi increase= 42.5 psi. 42.5/40=1.0625 square root of that is .03, or 3%.
Then we went on to talk about how close to the edge the car is tuned, what type of fuel etc. Tuning on E85/methanol/E98 he said he'd have no concern until atleast 6% and on gasoline if the car was run right on the edge 3-4% would be the limit.
In my case, I run the car pretty rich and after talking to him I am going to not be concerned with the 2.5% I am seeing.
Also, something interesting was he asked about the boost and if it was filtered. BINGO
I pointed this out earlier. I explained to him that the boost signal is filtered and the fuel pressure is not and then the difference became less relevent. The next time I do some testing I'll log both channels unfiltered if I think about it and post a new log.
