Hello,

I read your vehicle profile. It says your running a 4g64 crank. Is it standard size? where did you get it from? What kind of rods are you running?


you may need a safc in order to fine tune the MAFT.

One more thing, it's not how much power you make, it's how you put it to the ground that counts!

 

[Mirage2LTurbo]

Wouldn't the amount of power you make be directly proportional to the amount of power you make at the wheels?

 

[Cesar]

not always. engines make power and the driveline delivers it. For example if your motor makes a certain amount of torque, let's say 350ft/lbs @ 5000, and you stock clutch disk can only hold 300ft/lbs. then some power will be lost. same goes for tires than don't stick, when launching. That's why you should mod wisely. You can come up to a motor that can make 700 horses @ the flywheel, only to have your tranny explode and in the end you won't have any power at the wheels.
What kind of clutch are you running? Are you using the stock 90 tranny? has it been rebuild? If the driveline is stock, I wouldn't launch. I wouldn't dyno either with a stock clutch. Your AWD no?

Thanks

my friend told me I have a 4g64 crank, from a 2g jdm motor but I dunno I didnt build this motor so I wouldnt know, but yea thanks for the replys.

All those problems are either related to a driver incapable of launching his car, or you are overpowering certain aspects with other aspects of your setup. If I put my turbo on a stock motor, I'd damn well expect it to blow up in 50 miles. Same goes for the clutch, you need a stronger one then. If you're blowing trannies, you need a stronger one.

I don't really know why I'm bothering to reply. This statement alone says enough.
a 4g64 crank from a jdm 2g? Do you realize that there is no such thing as a japanese domestic market 2nd generation eclipse? In fact, no eclipse was ever produced for the japanese domestic market. This makes me wonder what crank you really do have.

Your goals are not very lofty so they should be easily achieved with that turbo. What you have sounds good, although I personally would not ever use the maf translator as my sole means of tuning. You will of course need a stronger clutch to hold that power and the other things you mentioned are good, but everything is in the tuning.

Which problems? a tranny blowing up? all kinds of tranny builders brag about their broken centre diffs, and so on...they break under stress, regardless of driver skill.
If your good at launching you can certainly avoid unecessary damage.
F1 cars blow up all the time. (very good drivers)
so do nascar, cart, indy, rally, so on and so forth. things will break when you are adding additional stress.

your turbo will only blow a stock motor if it is allowed to push a certain amount of CFM without inapropriate fuel ratios.

If you are making decent power you will break the stock drivetrain. A 1990 tsi (the vehicle in question) has a 3 bolt rear end. It will snap. But then again, if you got the stock clutch, your not even capable of launching. you'll just smell burning clutch.

90's also have single synchro second, and they grind at high mileage. Not the ideal tranny for launching.

well that's not possible unless you have stroker pistons.
