Custom home built CVD's for my 4-tec

[B Davis]

1. Since the stock plastic CVD system can't handle my bigger wheel/tire combo along witht the ported 3.3, I had to come up with something else to handle the power output to the tires. What I did was bought a MIP CVD kit for a T-Maxx and modified the stock 4-tec differential to house a new solid center shaft that now makes it a true locker to hold the axle hubs from the MIP kit for a T-Maxx. I then took one of the long CVD's from that MIP kit and cut it down, tack welded it to fit and sent that CVD out to a guy to custome make me new ones just like the one I tack welded. I now have basically a bullet-proof CVD kit that can handle just about anything I throw at it. I don't know about you guys but I really like making and having custom parts made for my 4-tec. I know lots or ppl don't like the 4-tec but I think it is a pretty good car to start with and build up to be a competitive car.

2. I also have new 1st and 2nd gears being custom made right now out of lightweight steel for durability as well.

3. For my big block RB engine, I am using a Jato fuel tank since it has clearance for engine clearance.

4. I have the bigger 1/8th scale wheel/tires and a 235mm Stratus body to fit as well.

What about you guys, anything you make or had made?

It's very cool that you have done all of this custom work to make the car fast. Props to you for putting big horsepower in a car and doing it the right way, where the power is not just wasted and useless.

However, I'm a little confused about the competitive part. I guess if you are racing in an unlimited/outlaw class that just runs in a straight line, then yes it probably is quite untouchable. Everywhere I race, the outlaw class is non-existent so I would have nobody to race if I had a car with these mods. I am a racer and not a basher so racing against noone does not interest me. I have an RB V12 Rody 5 port that's just sitting in a box because I have nobody to race outlaw with.

Terry,

Thanks but the outlaw bash racing is what we do. Most run for no less than $200 a race......drag race, no road course stuf for us here. Best 2 out of 3 takes the cash.

Here's my RB Concepts C-6 Xenon modded by RBmods.net This is the same engine that ran 1.59 at 88 MPH in 132'.



Here's a pic of the big tires that hook so hard that the stock CVD's just break at the hit of the throttle.

How can you run smaller tires in the front and larger ones in the back with an AWD car ???

Well, at $200 bucks a race your investment may actually pay off. We just race for bragging rights and the occasional bowling trophy. LOL

[B Davis]

Yeah we had to make up our own stuff around here or as you said, it wouldn't be worth it otherwise. Our local Firestation has drag race night every third Wednesday night BUT it is for bragging rights rather than a payout.

Terry, how well is your C-5 running and what is it in?

I don't have a C-5. I have an RB Concepts .12 with 5 ports that has been modded by Rody Roem. It is a screamer. Not so insane that you can't road course it, but you need a good setup and lots of traction. I had it in my MTX-3. Now I just have a stock 3 port RB .12 that's ROAR legal. It has been reliable for 3 seasons, but I bought an OS-TZ .12 Speed factory mod. It probably runs almost as good as my Rody, but is ROAR legal. Trouble is, I haven't raced this year at all with my work schedule.

[B Davis]

Ooops, sorry I was thinking that it was a C-5 big block.......dugh, I guess I should read better. LOL!

Get this, my C-6 has 11 ports in it. I have yet to run it but I have seen the same engine run and it was an animal.

Good luck with your racing schedule and post up any pics you have of your car as well.

Brent, I Just got my fresh of the dremel rb mod 3.3 engine....... After I seen the video of your tec I was sold on getting that kind of performance out of my car, so I had tower send me a brand new 3.3 and back plate cover($170) just so I could really see what kind of performance rick could get out of the TRX motor. Total cost with the buying a new bullet and getting it tweaked by rick $395.00, have'nt ran it yet but I did take a look at the internals and all I could say was "WOW"......He touched every part of my motor in some sort of way, he even modded the crankcase. I'm gonna check back later to see what other kind of mods you guy's have posted for the tec. [IMG][/IMG]

[B Davis]

WOW! Glad you went with Rick plus you have that new billet rod that he has. I will add that if you get one of those new .26 carburetors, that engine will be an absolute animal.

Check your PM as well.

[outlaw4-Tec]

Check your PM.

I did, for some reason my mailbox was turned off....thanx for the heads up dude.

[B Davis]

WILD72, those are MUGEN wheel/tires off a Mugen 1/8th scale chassis and have worked flawlessy so far. I've been 90 MPH with the car as it is with the modified 3.3 engine. Man you should see when the front end actually picks up when I hit the throttle on this thing.

[WILD72]

I would think because the car is an AWD that you would need different size pullys to compinsate the tires and that there would be some sort of binding. Have you tried taking off the front belt to see what that does ???

[WILD72]

On a real AWD automobile if you were to put larger tires in the rear and smaller ones in the front you would break the transfer case. On a 4X4 if you were to put a smaller size rear end ratio in the front than the rear you would break a differential and possibly the transfer case depending on how long it was driven for... Thats why it made me wonder about your car & the tires.

[B Davis]

No I haven't taken the belt off to see but I will. I also have a 15 tooth count pulley up front and a 20 count one on the rear to offset the speeds of front/rear tires. So far, no problems at all.

Thanks for the input though. It helps to have extra thoughts and information.

15 tooth count pulley up front and a 20 count one on the rear.

If the math was done correctly on the pulleys then I don't think there should be a problem...
