For the tire sized jsut remember it like this: The first number is the width in mm The second number the height of the tire in a percentage of the width. So for my 295/55/R15 the height is 55 percent of the 295 mm width By the sounds of it you want the look of something like my car: These are the rims I am using. 15x10 with 5.5" backspace: http://www.summitracing.com/parts/SUM-561-5162PS/ I like the 15X10 wheel, it really spreads the tire out and makes it look full and also a better contact patch than using a 8" wide rim. My tires are 285/70/15 and they fit with not mods: For the track I got a spare set of the same 15x10 wheels with 295/55/15. I could fit a bit wider tire but I like to have a little extra clearance:
Huge rims and tires on the floor right in the main area of the house, and pistons sitting in the corner. You are a lucky man! :laugh: Those will fit perfect. Same exact rims right?
They will fit fine.. My 325/50s just needed a slight trim....I really like the tall tires you have on the car.. Anything else like that out there??
Based on the numbers.. The 295/65 should fit fine.. Just depends on how much it flexes in the turns. I do not think a taller tire will slow me down at all. There is so much torque I doubt I will ever tell a difference.. If the tire rubs it will leave a mark.. That's where you bang on it with the hammer right??:grin:
Keep me posted if you do try them! Both our cars were so rough when we started that we really can do whatever we want to them without feeling badly. Some guy at work was asking about the car and if it was a 455 GS, I said no just a 350 Skylark. He asked if I was going to do a 455 swap I said no I just built a mild 355 inch for the car, and had a roll cage installed. He just kind of looked at me shook his head and said the 350 was a waste of money and the car would be too slow to need a roll cage.... Maybe I will have to take him for a ride since I am sure he will not even want to see the 350 under the flat hood. I might have to put some oil obsorbing sheets on the passenger side though LOL. he never asked if it was turbocharged LOL!ou:
Funny.. I had three big passengers and pulled more Gs on the street than I ever could with just me in it.. Guess it got better traction..
I would guess it was the extra weight causing more load against the engine and this causing the boost to come on harder and quicker. Turbos love resistance many people run faster in the quarter mile with a 2.73 gear than a 3.73 gear just due to more load against the turbochargers. You just might find your car pulls harder for the same reason with the taller tires if you do go with them. I know a guy at work who runs 9.1 @150 MPH in the quarter with his twin turbocharged Mustang. He started out with a 4.11 gear, went to a 3.55 and finally to a 3.00. Each time he went with less gear his 60 foot time got better, his 1/8th mile was faster, and his quarter mile time. He was running 130 MPH with the 4.11 gear so the 3.00 gear picked up HUGE for him. He said the car pulls better and makes more boost quicker. I think he is running about 20 PSi of boost, and I know he just got his cage re-done so he can run in the 8s.
A possible explanation for it being faster with more weight may be a change to the yoke angle with more of a load! It's a proven fact the closer to 0 degrees the better. I've been told -1 is best for an A Body car!
Could be. Either way it is great it feels faster with more weight... I guess jay needs 4 passengers in the car when he goes to the track LOL!
I know me too! It is a long road ahead with this project, I work WAY too much to get things done quickly. I am about to place an order with TA to get the last few things I need for the engine, then a few trips to the local parts store for some random things like battery, fuel pump, fittings, harnesses, parachute etc. The main things I am doing are: -Completing the fuel system to handle 1000 HP -Adding the driveshaft loop -Dropping in the good Buick 350 -Putting the interior together This will get the car up and running and will start with 8 PSI of boost, get the car insured and plated and put on a few miles and break in the engine. The next phase will be the next winter where I will pull the th350, move the X member and put the built up SP-400 trans in place, custom driveshaft, Water/methanol injection for intercooling, crank up the boost to 20 PSI, sort out the tune on a chassis dyno, and finally some track time in the summer of 2014:TU:
sean...just for 2 cents worth ...when I was using boost I found that water only and no meth worked the best...( with a smaller motor and 26lbs. of boost ). Hope all your projects work out great and keep us up to date !!
