Every single turbo car should have electronic wastegate control, without it is a shame against what the turbo can actually do. Best modification I ever did to the GTX.

Update: Just talked to him. I asked if he is going to the dyno again, he responded "that the tracks open in a month, no more dyno..." So we might see some action out of this car soon. If it ran 9.30 with less motor, I can wait to see what it does now.

He went to Pueblo Motorsports Park for some licensing passes. He is really closed mouthed now about everything since it has come to his attention that many of his fellow are following some of the posts about the car on the internet. I am not sure why this should matter but it matters to him. What I can tell you is that he sent me a video of the car running a license pass and the end is clipped off of it. What he is saying, is that the pass shown is a 5.82 @ 120mph in the 1/8 mile. Also stated that this is with only a 4 psi launch, and max boost controlled to only 13 psi. The tables I look at show a 5.82 is ~9 second flat. Not bad at that boost level. The first races start soon so everything will be out of the bag anyways. I will keep you updated. If this goes the way any other car of this type I have seen put together, we will likely see some disappointment related to mechanical drive train breakage. Then some really nice numbers.

Is the quiet nature of it due to keeping a surprise for future competition or the like? Either way, it's still one of my favorite projects. He's done an astonishing job.

I'm glad to see at least a partial update - this is one of my favorite AI project cars just because it's so obscene. I'm unfamiliar with drag racing though - is the 1/8th pass just to make sure his cage, etc holds up to scrutiny considering the speed of the car (that is, the "licensing" is to approve the car for safe operation on the track)? Our local strip doesn't require a cage until you break (I think) the 13 second quarter.

He actually cleared it up for me. I was wrong. I jumped to a bad conclusion. I had a talk with him and he set me straight. Cutting the video had nothing to do with not talking about how the car performed to his fellow competitors. It had everything to do with smoke. He changed tire diameters and the tire growth made the new tire rub on the inside of the quarter panel and it was a huge smoke show to the finish line. He bent the inner lip of the quarter panel at the track and made a few more 9 point teen second passes, but there was no other video shot so he had to post what he had. It may seem childish, and it actually is. This has more to do with a long standing childish habit of our group of racers giving each other a hard time about "blowing it up". Instead of having huge arguments about what is tire smoke and what is a blown up engine, he just shortened the video to remove the temptation of nay-sayers. it goes like this; a tiny bit of smoke from your car and all of the sudden jealous detractors will be spinning stories of how XX car blows up every pass and is rebuilt at great cost every week between races because its not as well put together as YY car and somehow less of a street car. The problem is, that there are so many insanely fast street cars in such a small town that the jealousy is caustic and viral. I am not sure if I have even done a good job of describing the situation because it is so childish. But having the first words of every person who looks at your car as "heard you blew it up already" gets old fast. I know because I have experienced it myself.

 Massive Update B4Ctom1 posted:Bandimere Speeedway, Coys Street Machine Showdown, Ultimate Street Class, Today Two passes to win and qualify because nobody else showed up. Both passes on 20 psi of boost at Bandimere's 5860 foot altitude. 8.77 and 8.76 both at 160 mph in the 1/4 mile.

Though we were chatting the other day about a Gearvendors overdrive to improve highway cruising. No other transbrake OD's seem to survive. Not 4L85E's not AOD's. You will read about one occasionally doing it with one of those trannys. Then you read about lots of guys in race/cruise/drive competitions ALL running the GV OD unit on TH400's and Glides, even in non-GM's. We discussed the fact that he wants to go to Bandimere, run the class, and drive it both ways making the 280 mile round trip all without ever putting it on the trailer. Read some here about it: http://www.gearvendors.com/racing.html They mention the HotRod Dragweek winner ran 7's in a 3800lb car and made the entire multi-track drive using their unit. http://www.hotrod.com/upcomingevent...eeks/index.html Hot Rod Magazine posted:Drag Week puts competitors'vehicles to the test at five dragstrips on five consecutive days in fivedifferent states, and the lowest average e.t. wins. The kicker is thatall vehicles must drive from track to track with no trailers or supportvehicles allowed, so over-the-road dependability will be just asimportant as brute acceleration. And unlike Pump Gas Drags and heads-updrag racing classes, there are very few rules and you can do whateveryou want to the car at any time, so long as it doesn't involve a traileror a support vehicle. Everything you need, including tools, parts, andspares, must be carried from track to track in the vehicle or in atrailer pulled by the vehicle.

If it were "filled" then it wouldn't be a street car at all. A partial fill just undoes where the factory got carried away trying to over engineer cooling. A partial fill is trading a little cooling for a lot of strength where a total fill trades all cooling for a lot of strength. Doing this in a car that had poor cooling capability through compromised airflow to the radiator or an abbreviated radiator do to space requirements would possibly begin to create an issue.

Good ol turbo cars, lazy as hell in the front half and then turn into rockets out the door. What's he doing to address that 60'? It's not terrible, especially for a turbo car, but it's definitely not up to par for an 8.7x car.

Update: He has won his class (Ultimate Street) every time so far when entering except at ONE location. At that location they moved the race series to a more remote track for a race. Because of that remote location only a few cars showed up. So they combined the class with another racing class where he was still only edged out to 2nd place finish by a car that runs 7.80's. His best time so far with the same soft launch method is: 8.61 at 167 mph He can run faster, but anything faster than a 8.50 will get him kicked off the track as his car is only certified to 8.50. I just wanted to say that this car is so fast that his class, Ultimate Street, is considering a rules change to try to slow him down. They are considering a change to limit the class to only a single 88mm inducer measurement. On his car, limited already to 8.50, already limiting the boost as he is, he will be able to run the same times with an 88mm turbo!

He should fit the 88mm, and then promptly do a run as far below the certification limit as possible. Bonus points for convoluted excuses involving "Less spool time off the line with the smaller compressor" or similar.

Turbonetics told him they think the way he is under-utilizing the 106mm that the 88mm might actually make his car faster. Our discussions yesterday varied. He wants to possibly update his cage to 7.50 this winter. He also wants to build a bigger engine using the new large bore GM LSX Bowtie block. This block utilizes the new 6 bolt cylinder head bolt arrangement. You can read about this block here if you are an engine nerd like me (3 pages): http://www.gmhightechperformance.co...lock/index.html more info and a short build up: http://www.superchevy.com/technical...uild/index.html Here is video of one making 2000hp on a dyno with turbo: http://videos.streetfire.net/video/...P-on_168394.htm -Spiffy- posted:Makes for a less impressive photo of him on the couch with bedroom eyes however. Those aren't bedroom eyes, those are exhausted eyes. He has more things going on in a day than anyone I know. He told me yesterday the hardest thing about running this car currently is not having enough tuning time with it.

TurboLuvah posted:Could I ask what advantages there are with an EWG control to a mechanical one? Is it just the fact that you can fine tune the openings instead of relying on a spring loaded valve? They all use a spring loaded valve, you just adjust the pressure going to the wastegate, letting you keep it closed until you get close to full boost, rather than it 'cracking' open at small boost pressures. Thats why modern cars come on boost much faster than ancient turbo cars like mine. Lets you run much larger turbos, too. Nothing but a valve that pulses to lower the pressure going to the actuator. I changed my 10psi actuator for a 5psi one with a PWMed valve so I can go all the way down to 5psi but can run anything I want up to the surge point of the turbo.
