MARK 99STS Posted January 26, 2006 Report Share Posted January 26, 2006 We tunned the car today and did our first WOT to redline. OH MY GOD!!! We pulled to redline. Almost no turbo lag at all. Full boost came at 4800rpm and flatlined at 7psi and stayed to redline. And this car pulled Freaking hard as sh.....!. Jim thinks it may be low 12's -high 11's if we can shift right at peak power. The dyno will tell us where that peak is at. Stay tunned for dyno results. Any body know how I can get a video up without taking forever to load or on what site? I can take videos with my still camera. MARK 99STS TURBOCHARGED Link to comment Share on other sites More sharing options...

BodybyFisher Posted January 26, 2006 Report Share Posted January 26, 2006 Mark, if you run it on a dyno to determine output, I would love to see that. I know at some point you will run it on the track but I am sure you will be doing some testing first. Thanks, Mike Regis is speaking about the video file size.

We were street tunning all afternoon on a desolate road with the wide band. Regis, What is the max file size for the video. I may do a couple. One inside the car and one outside as the car goes by.

Regis Posted January 26, 2006 Report Share Posted January 26, 2006 Hi Mark, I just added a new site to house your video with sound. Try to keep the file size around 10mb or less. That should give you enough room for a decent video. Good luck!

TDK Posted January 27, 2006 Report Share Posted January 27, 2006 Mark 99 STS, Are you using any onboard diagnostics for the tune? Does the "piggyback" computer mask this I/O? For example, are the onboard o2 sensors active? Did you add any aftermarket exhaust temp sensors? The fundemental question here is; how are you determining acceptable air/fuel ratio at max load? Are the "redline" or tranny shift points limited? In a issue related to drag times, how is the ""traction disable" switch working? Regardless, congrats all around! Add power to leave problems behind. Most braking is just - poor planning. Link to comment Share on other sites More sharing options...
BodybyFisher Posted January 27, 2006 Report Share Posted January 27, 2006 I will let Mark provide details, but from my brief discussion with him, Mark said that, the piggy back computer provides the on-board computer with an calibrated "image" that everything is as the on board computer expects. It kind of fools the on board computer. Sounds like a Star Trek episode to me!

OynxSTS Posted January 27, 2006 Report Share Posted January 27, 2006 Honestly, this is the best news and most exciting thread I have ever read on this board. Mark is blazing a trail for the rest of us... I only hope 1) Mark has patented some of his designs 2) The aftermarket approaches Mark to develop some kits 3) That our old guru friend is lurking to see this progress and success... Should bring a tear to his eye.... The little engine that COULD! Nice Job MARK!

JasonA Posted January 27, 2006 Report Share Posted January 27, 2006 The little engine that COULD! I'm thinking more about "the little transmission that could". I don't know how much "strengthening" components Mark has added (I know he's done a high stall converter), but something like this really validates the strength of the many components like the transmission case, CV joints and half shafts, etc. Jason(2001 STS, White Diamond) "When you turn your car on...does it return the favor?"

BMWburner Posted January 28, 2006 Report Share Posted January 28, 2006 I think I speak for all of us when I say that this is one of the coolest thing I've seen all winter. The layout and location of components is stellar. I had no idea the exterior would look more or less stock when completed. I can't wait to HEAR the beast let alone see it. Nothing would be more cool than sitting at a stoplight and hearing what sounds like a built out twin turbo Supra roll up behind you and blow of enough o2 to preasurize a lear jet's cabin and see an STS. I agree with Jason in his concern about the tranny. It looks like he's got the tranny oil cooler from hell, complete with fan on top of other drive train mods so we'll see. That's alot of power. I would be even more satasfied to see the tranny take the tourqe with stride, I'd never hesitate to boot it ever again.

MARK 99STS Posted January 29, 2006 Author Report Share Posted January 29, 2006 We finished up some drivability tunning this weekend. So far so good. I took some video, but I don't have any editing or compressing capabilities. The first one is about 17 meg but could be shortened if edited. The second is only about 2.5meg. Someone let me know and I can zip them and email them. I built up the rpm at the line with the converter to about 1800 to see what it would do. I side stepped the brake and goosed it about half throttle. It was absolutely wicked!! It is so powerfull I am concerned for the tranny! There will be no heavy down shifts or WOT redline shifts. Jim and I don't think the tranny can take it. If I do a track run, it will be letting off for it to shift and then get back on it. It will kill ET's but better to save the tranny. If this car does 400 at the wheels, that is in excess of 500 at the flywheel. Thats crazy!! We feel mine is putting out more power because of the open Corsa exhaust, the 3600 stall converter(which puts it RIGHT in the power band) and the fact I had the exhaust side of the heads ported along with the LSD. With a bone stock car, it probably won't put out as much, which may be a good thing. Neither of us can believe how much power this thing is producing.

We are tunning thru the MAF which we can control thru the piggyback, and we are using a widband to know our AFR trims. The stock 02's are not being used as the wideband is sending converted info to the stock PCM MARK 99STS TURBOCHARGED Link to comment Share on other sites More sharing options...
BodybyFisher Posted January 29, 2006 Report Share Posted January 29, 2006 You can send the videos to me, but the 17 meg file will be a problem, I think most email servers limit file sizes to 10 megs. I can edit the video if you want. The engine sounds amazing. What can be done to the tranny to make it stronger?

danbuc Posted January 29, 2006 Report Share Posted January 29, 2006 I knew the trans wasn't gonna hold...hehe. Mark, if you want I think I still have the link to that place in Harriman, NY that does performance build of GM transmissions. They could build one for you that could take that power. When I spoke to them, they said that they have done a few 4T80E's for people. Crap, I can't find the link, and I don't remember the company name.....oh well. I'm sure there's a few places around that can build up the 4T80E to withstand that much power. Link to comment Share on other sites More sharing options...

I'm sure there's a few places around that can build up the 4T80E to withstand that much power. Correct me if I'm wrong, but isn't the 4T80E based on the 'ol Turbo 400 which is famous for surviving behind every thing from School Buses to 9 Second Dragsters... The 4T60E is based on the much weaker 700R4 and those can easily be built to withstand 500 ft-lbs. I'm betting that a stock 4T80 will handle 400 ft-lbs easy.. with the work Mark has done and the stronger diff he should be OK... But a performance tranny shop will know for sure.

BodybyFisher Posted January 29, 2006 Report Share Posted January 29, 2006 Mark what makes you think the tranny can't handle it? Maybe this is why, I found this: Most of the new motor's specifications are still hush-hush, but it has been said that the 32-valve, quad-cam mill (for the most part a carry-over from the Cadillac-based Olds Aurora V8) will more than likely share the Cadillac 4.6-liter Northstar's architecture and all-aluminum construction. In fact, the GXP's motor could very well be a de-stroked version of the L37 Northstar producing 285 horsepower. How much torque it will make is anybody's guess--we're willing to bet that GM won't have to push the 305 lb.-ft. torque capacity of the 4T80E transmission, but needs more than the 280 lb.-ft.-rated 4T65E can give.

It's kind hard to base the design of a transaxle off a conventional RWD tranny like the TH400, or TH350 for that matter, since that's pretty much what the TH400 is. The TH400 is pretty different from the 4T80E in many ways. The 4T80E is a strong transmission, but I don't think it's 400whp strong. Link to comment Share on other sites More sharing options...

I'm betting that a stock 4T80 will handle 400 ft-lbs easy.. with the work Mark has done and the stronger diff he should be OK... But a performance tranny shop will know for sure. The stock tranny may handle 400 ft-lbs. But with most turbo applications, the torque is increased drastically. Jim thinks that if we make 400hp at the wheels, it will be 460-470ft-lbs of torque. That is what bothers me. When I dynoed it before it was 250hp and roughly 254 torque. And that was a dog on the low end. Now, God only nows what the torque is on the low end as this thing is a beast. Maybe it is a good thing that the tires blow off so easily as that releases a lot of stress on the tranny, especially since I have the LSD. What scares me is the day I go to the track, let the pressure out of the slicks, bring up the converter at the line and the car hooks. Talk about some stress!
