You think i will blow up the engine? I think it will stay in one piece. It's very quite at speeds and idle....if you ask me it sounds like a new engine. I want to keep it like this....will not race the stock engine, that would be a huge waste! Thanks man
OK, so it's no problem to install instead of 75 wall size, for example 70 wall size tires on. I want to put the period correct red line tires on sometime by Goodyear or Firestone and i don't think you have them 235/75/15........ only 225/70/15 (G70x15) ? Thanks!
Robbie, I think what Chris meant is, that at sustained high RPM for more than a few minutes, the oil might not return fast enough to the pan, and the oil pump could empty the pan, and you could run out of oil, which would be disasterous. I know this has happened to guys that used the High Volume pump kit. For sustained high speed/RPM, I'd want a bigger oil supply(bigger Pan), and overdrive to cruise at high speed on the autobahn. I have a Gear Vendors Overdrive on my GS. It has a .78 overdrive which makes my 3.42's like 2.62's It bolts to the back of the THM400. It's pricey, but bulletproof. www.gearvendors.com
OK Larry, then i miss understand him......Is it possible to install an overdrive on my TH400? I have a steer column shift, isn't the TH700 a 4 gear automatic (overdrive) ? Will it be possible with an overdrive only to drive like a 100-110 mph for trips like 80 miles or so continously?
Yes, click on the link www.gearvendors.com Read about it. With my overdriven THM400, 110 MPH would come at less than 4000 RPM The Gear vendors installs to the back of the 400. It can be engaged in any gear, giving you 6 speeds instead of 3. Click the link and read.
OK, thanks....maybe i should keep my cruise speed at 60-70mph..... that would be an expensive modification.
Robbie Do you know about speed ratings of tires ?? Basically - the faster you drive, the more heat is generated by the tires. Tire manufacturers change the compounds used in their tires to make them able to handle this increased heat - usually at an increased cost to you. Tires that are designed to drive for long periods of time at "normal" highway speeds (60-75 mph or so....) could have total failure at speeds of 110-120 for sustained periods of time. Im not sure what this timeframe is, but it isn't long at all - couple of minutes. Be safe....check it out
Yes, you are absolutly right, thanks. And yes, i know, i have Cooper Radial white line tires and i have to look at what highest speed they are rated first....i know it could be very dangerous to go for top speed without checking the tires first! Thanks man
