My question is how could there be such a noticeable difference in how fast my car is from doing this???? Is it because I didnt have the whole front driveshaft removed???? Most seem to report the car seems more nimble, mine does not, it feels heavier actually. I also noticed this when I rode in another forums members car who had the exact same mods on it as mine, his car felt slower and didnt pick up as fast. It really doesnt matter at this point as I am AWD from here on out but I just wanted to know why?????? And it's not wheelspin either because I am talking about straights, and I didnt get spin on the exit, acutally got out of the turn better in RWD. Well here are the results.....



I have been deliberating about this for some time and was going to wait for lap times to decipher and conclude which was faster around the circuit. But there are too many factors in going around the track that could be misleading.

#1 My learning new things about the track, different techniques that make me faster in certain corners.

#2 RWD does have it's advantages in slow turn in corners while AWD owns the sweepers, depending on the track your on will determine how much that affects your time.


But to the results. My conclusion is based on not only lap times but my traqmate system which allows me to run different sessions next to each other and even same laps from sessions next to each other. I took all of the laps in RWD that were similar in time to my AWD best because that would put the dots close enough to where I could see which was faster on the straights. The results were pretty amazing, the AWD put carlengths on the RWD on the back straight and I could feel it while I was driving, I didnt blow past cars like I was before and slowly crept past a Z06 while I had better corner exit. The AWD would get worse corner exit and still walk the RWD on the straights In fact the only thing that kept the RWD laps up with the AWD laps was Me carrying more speed into turn 1 and not over braking and me staying on the gas longer going into 10a and braking much later. So now I have to conclude that the only thing keeping me in the same time range with the RWD was the tires which were much better than the previous ones I ran with AWD and the little things I learned to make me faster around the circuit, when I drove the AWD I felt like @ 1:38 I could get more time down pretty easily(capable of 1:36 on the street tires with more practice) , with the RWD I felt like I was lucky to get 1:36 and couldnt run it consistently.

 

Told you dude - Neil sold your K24's! Seriously, when you go back to AWD it will be interesting to see if this resolves the power/speed issues. You may have another problem (i.e., MAF) that coincidentally became a problem about the same time you did the front shaft removal. It certainly is a mystery that I would like to understand better.

 

I dont think it's a MAF, I'll be getting my AWD put back in within a week so I'll have to see from there, but I'm pretty positive its the RWD. Heck I reached 165 on the back straight in RWD so the MAF's are fine, I would venture to say I could get to 170+ if I get a good corner exit from 7 and stay on it longer in the AWD.

 

based on my knowledg that ive aquired on 6 speed... that does NOT sound right...

based on everyones experience, the rwd is significantly quicker... why don't you just remove the front drive shaft and diff first and try it again ...

 

I am not a pro, but since you didn't remove the front driveshafts, could they still be causing some kind of drag in the front diff. Since there is no power going to the front, could the diff make more drag?

My reasoning and thought is like when you have a remote control car with a rear diff. Try pushing the car on the floor and there is drag (of course some from the gears and motor), but when you lift it up and spin a wheel by hand the wheel spins freely, and the other wheel spins in the opposite direction. If the diff was not present, the wheels would spin at the same speed....and the only drag with a remote control car would be the motor and gearing. Hope this makes some sense. (If this statement sounds way far fetched...let me know so I can remove it and not sound like an idiot)
