Re: Land speed 1516cc turbo
World of Speed 2018. We arrived Friday morning and went through tech. After the drivers meeting we fueled up with ERC 110k and got in line. We made the first pass on the short course. The car ran decent, but only 7 lbs of boost. I showed 129 mph on the GPS and went by the timing tower. They had no timing slip for the car and said it crashed the computer and to go to the front of the line and try again. On the second run it was a little richer and GPS only showed 125 mph. We went to the timing tower and the same thing. No timing ticket and they said it crashed the computer again and then they entered all of my information manually. We went back to the front of the line again. By this time it was getting hot outside and the engine was starting to get a little hot. I noticed that oil pressure was a little lower and the AFR was even richer. On the 3rd run we finally got a timing slip and it showed 114.431 MPH. We took it and went to impound. The next morning the car ran great with the cooler air and we managed a 126.751 mph pass with the same tune. We went back to impound for Dan Warner to certify the record and #8 for the car was set at 120.591 MPH in H/CBGALT. I did a class change to the fuel class and got back in line around 12:00. The winds came up and we were put on wind hold for the remainder of the day. The next morning we were #2 to run on the short course. I had been turning the boost controller up a little at a time each pass and it was just starting to raise the boost off of spring pressure. The pulled hard and ran pretty good at about 8 lbs of boost. We ran 128.45 mph and went back to impound. They announced that we could do backup runs at 1:00 pm, 5:00 pm, or the next morning. We din't know how the wind or weather would be so we decided to go at 1:00 pm. The thin air killed the car. It was so rich that it wouldn't pull over 3,000 rpm in 1st and second gear. Finally in 3rd and 4th it started to build boost. I showed 129 on the GPS so I figured it made up for it at the end of the run. When we went to the timing tower and looked at the slip it showed 14 mph average from the 2-3. We complained, but they said that there were no problems with any other cars so it must be right. We had to use the 1-2 miles times which were terrible due to the rich conditions and no boost, but we were tired and ready to head back home so we took it back to impound where the 9th record was certified at 101.282 MPH in H/CBFALT. It was a fun year on the salt. I'm already thinking about next year and which direction to go. Lots to think about and work on this winter.

Re: Land speed 1516cc turbo
Congrats on your 126mph. Faster than I've ever gone. Sorry to hear about the frustrations, but keep up the good work. Do you get to drive the car on the street too?
BTW, have you thought of trying to find a dyno at the same altitude as Bonneville? You could tune it up there so you'd be ready for the thin air.

Re: Land speed 1516cc turbo
The air density changes so fast out there, I think I need a weather station to monitor and just start making notes. On my morning run the AFR was spot on and the car pulled good. The corrected altitude can change from 4500 ft to over 8000 ft in the same day.petew wrote: ↑Thu Sep 20, 2018 3:47 pm Congrats on your 126mph. Faster than I've ever gone.

Re: Land speed 1516cc turbo
I have a question with the 40 DHLA. Can you delay when it starts to richen up? My carburetor goes extremely rich at around 3000 rpm and noses over. I don't start building boost until 4,000 rpm. I am at 11.5:1 on boost so I don't want to lean it out on boost. Is this a lost cause, or is it more a size on the turbo, And I need to go smaller so it builds boost sooner? My cam only really pulls from 5k to 7500rpm, but I can't get it up to 5,000 rpm in first and second without it nosing over. Any ideas?

Re: Land speed 1516cc turbo
about the only way to fix a sidedraft is to make it a progressive as in primary & secondary circuits
like a 4 barrel carb
What size is ur turbo? and whats it on motor wize?

Re: Land speed 1516cc turbo
Or just use a 4 barrel.

I was hinting on that
but maybe the 'rules' don't allow?

Re: Land speed 1516cc turbo
I used a 4 barrel on my 1915cc. I was just concerned on the velocity due to this being a 1500cc engine. I guess maybe a 390 cfm 4 barrel or something similar would work with a smaller intake manifold. I am also thinking of trying blow through with a 2 or 4 barrel. It just all has to stay under the decklid.

Re: Land speed 1516cc turbo
Hit me up. I have 4 small 4 barrels and 4 small 2 barrels. I even made blow through manifolds you might be able to sweet talk me out of. I've tried them all and didn't notice much difference between them. The 4 barrels are far more tunable though. I haven't tried blow through yet though. They were all in a draw through configuration.

Re: Land speed 1516cc turbo
I would like to see what the blow through intake looks like. I don't know if a 4 barrel will fit with a pressure hat on top. I do like the tuneability of the 4 barrel in draw through, but my setup has a lot of up hill anti gravity sections that make it hard to start with a draw through setup.buguy wrote: ↑Wed Oct 10, 2018 7:58 am Hit me up.

Re: Land speed 1516cc turbo
It's really just a funnel with a flange on top. Would probably need some sort of turn on the bottom to make it back to the intake without hitting stuff up top. This is the 2 barrel intake I made.
