AugustBurnsRed19 Posted January 14, 2014 Report Share Posted January 14, 2014 there is some mis-information here...... but anyway, does the class you race have guidelines? rules? if its unlimited, how far do you want to take it? what are you looking to spend? you not reaching 140mph is a little strange IMO when you say it fell flat on its face in the 130mph range, can you describe it any better? I bet its in your tune, also converter. Please explain? Quote Link to comment Share on other sites More sharing options...

garrell.770 Posted January 14, 2014 Author Report Share Posted January 14, 2014 I was allmost complete with a long reply and the thing went away but a quick recap. I have made enough passes landspeed racing and dragracing I could tell on the last outing when that when my truck left the line and quickly reached 6,200 RPM that it was on the pass that I had been looking for but when it shifted to 2ND it fell back to 4,000 RPM and it like a car with the parachute out and didn't reach 6,000 RPM and shift again until just a few hundred feet from the one mile traps. One thing I forgot to mention is there are one half mile traps and on each run,4, I was 109.XXX and never varied over a few tenths so the truck was always consistant. There are limitations but since I moved to the modified class not as many but I can't run nitrous or run a blower or turbo. I pretty much blowed my budget with the last modifications plus tires, then I did some work on my Corvette. I had planned on tires and a complete rebuild of the brakes on the RS SS 69 Indy Pace car Camaro convertible and I don't take anything out of any of our CD'S or MM accounts.,Fortunately through blind luck I made some good investments and my a Wife and I both always had good jobs and very good 401K'S because I had to retire early because of three strokes within a month that put me in a wheelchair for over two years and Doctors said I would never walk again., Today I walk very slowly with a walking stick because of Parkinson's Desease. I can put the Camaro on the back burner and use that money out of my car account on the truck. I plan on a 2500'RPM stall converter and I may have to freshen the tuneup so I would hope to get the truck back up to speed for $2,000.00 if I can zero in on what the problem is.

garrell.770 Posted January 14, 2014 Author Report Share Posted January 14, 2014 One other thing I asked that the shift points be set at 6,200 RPM so if will help I can have them changed to 6,500. Quote Link to comment Share on other sites More sharing options...
kcsilveradoss Posted January 14, 2014 Report Share Posted January 14, 2014 Not sure where a 6500 rpm shift helps a 4:10 geared truck. Quote Link to comment Share on other sites More sharing options...
garrell.770 Posted January 14, 2014 Author Report Share Posted January 14, 2014 I just thought it would get me farther down the track and maybe pulling hard in second gear when I crossed the line.,The biggest problem is falling off so much in 2ND and 3RD gears. If the engine isn't missing or stumbling then it has to be a loss of transfer of power to the ground. The transmission isn't slipping so it almost has to be torque converter related and the more RPM'S you are turning when you go through the lights the faster you are going until you run out of gear!

Yo N A good converter will keep your shift extension short and at or above 5k rpm so it won't feel so sluggish between gear shifts Quote Link to comment Share on other sites More sharing options...
onebadmax Posted January 15, 2014 Report Share Posted January 15, 2014 How do you know your transmission isn't slipping? Quote Link to comment Share on other sites More sharing options...
chpspecial Posted January 15, 2014 Report Share Posted January 15, 2014 Not doubting your tuner, but you might want to recheck the tune. And second just because a cam is advertised to "xxxx" rpm, doesn't mean you should shift it there. If the truck is no longer pulling in one gear, shift it. That intake manifold and cam are not well suited to each other. One is a high rpm flow, while the other is more of a low end torque towing application.

garrell.770 Posted January 15, 2014 Author Report Share Posted January 15, 2014 I have not wanted to put any blame on my tuner up now saying that the cam and the intake were at my suggestion, I bought the intake after months of research and was convinced that it would offer the most bang for the buck but I also told the owner and his shop manager the RPM range that I wanted to make horsepower and for them to choose a cam that would meet those requirements. I actually asked for a cam that would peak from 2,500 to 5,500 thinking that the quicker I could get into 3RD gear and recover and pulling hard when I went through the lights. You got to remember I am from the day of putting a 340 HP a Corvette a Engine into a 57 Chevy using a large limb of an Oak tree to hang the hoist from, true story many times over. I told you about being imprisioned for two years in a wheelchair because of three strokes but I didn't tell you that I also suffered 100% memory loss and have had to relearn how to do everything so you have no idea how much I am beating myself up over this. I was the hero to everyone for breaking a six year old track record in my class on the Maxton Mile and after I set two records on the Ohio Mile I was the lead off story and my situation was discussed again in the last two paragraphs in the July issue of a HotRod Magazine. You think I didn't feel foolish when family and friends started calling when I got home from my last trip all knowing that I anticipated running 138 MPH not knowing I fully expected to run over 140. I even expected to have to back off on the first two or three runs because if I ran over 140 MPH I would get one warning to not run that fast without a 8 point cage, a fire supression system and a head and neck brace. So I was going to retire from landspeeed racing and run the truck as well as my Corvette on the 1/4!mile five or six times a year. So just for my feeling of personal achievement I have got to go back one more time and at least run in the 137 MPH range which sounds like a tall order from the 130 last time but only 2MPH and change from time before last and I probably have at least 50+ more HP.

AugustBurnsRed19 Posted January 15, 2014 Report Share Posted January 15, 2014 Don't worry about the intake if it's the LSXRT its definitely a badass intake! It's the cam my Cam's power band says 2200rpms-7200rpms now that doesn't mean to get a 2500 stall and it will launch perfectly no. I need atleast a 3600 to launch with this Cam and believe it flys off of the line. As for my first gear shift point thats at 6800rpms you're gonna need some higher shift points if you want to fly on top end! Quote Link to comment Share on other sites More sharing options...

I think you will be fine as long as you shift the truck earlier. Try using your tow/haul button (as long as the t/h settings haven't been changed). By default it shifts sooner than normal. Try it, if it improves your time, you're holding gears to long. Sent from my HTC6500LVW using Tapatalk Quote Link to comment Share on other sites More sharing options...
garrell.770 Posted January 15, 2014 Author Report Share Posted January 15, 2014 Everytime I am almost complete with a post on my new I-Pad I lose it before I can send it so I got the old lap top out. Looks like it is a given that I need a new stall converter, some say 2,500 some 3,500. Is there a happy medium is there a 3,000 stall speed converter and will that do the job. Who makes the best converter and about what will the cost be? There a young man here in town that has a nice transmission shop and he is into high performance cars and owns a Z06 making over 600 RWHP. He checked my truck out and says the transmission is not slipping but he agrees that the torque converter is part of the problem. He will install a new converter for $600.00 and me furnish the converter and he will install a shift kit in the transmission at the same time for whatever the cost of the kit is. This a large four lift shop so spotless you cold eat off the floor and he was the transmission specialist for a large dealership in Atlanta. I don't have much alternative for a tuner, their speciality is Ford products and there are some really fast ones that come out of it. They have already said to bring my truck back and let them put a torque converter in it but I actually feel better using the local guy. It also sounds like almost everyone agrees that maybe I need to raise the shift points could the transmission shop do that. When I crank the truck it automatically revs to about 2,000 RPM'S then drops down to around 900. I carried it back before my last trip to Ohio and asked them to check for a vacumm leak which they did. I was told that they used quite a few of the same cams as mine in late model Camaros and Corvettes and reving up like that was a characteristic of the cam. I was also shown dyno runs on some Comaros with the same cam that produced more than 45 HP to the rear wheels. I really can't afford to pay to change cams again, I can handle a new torque converter and I can pay for a new tuneup but how much is that going to help without a dyno?

Aldofashow Posted January 15, 2014 Report Share Posted January 15, 2014 I daily drive mine with a yank ss 3200 and its all good with no problems if your gonna tow anything with the truck you need to let who ever you order from know that. I only tow a jet ski and they said I'd be fine Quote Link to comment Share on other sites More sharing options...
garrell.770 Posted January 15, 2014 Author Report Share Posted January 15, 2014 It will never haul anything but luggage under the tono cover no towing I have thought about removing all the hitch related components to shed a little weight. I am open for a Mfgr. And stall speed for a converter and a definite shift RPM for the transmission. Seems like everyone is okay with me using my existing ported 90 MM throttle body and an adapter with the LSXrt intake. You think it is getting enough air, what about fuel I would think it is sufficient. I am just trying to summarize everything and start getting the work done. The first Show N Go is in April and I can tell in my comparison 1/8TH mile et. and speeds if I am back where I was or better. Quote Link to comment Share on other sites More sharing options...
