Default If I have a 10vt with CIS, how do I fine tune the engine

Sorry to ask such a newbe question but how it this done
I have a 80Q and decided on a 10vt motor (just bought the hole car/crashed)
I read that I can make pretty high HP number with this injection but how
I saw someone say I could make 280hp with a "very very fine tuned CIS system"
Is this possible and how do you do it
Looking to start the swap very soon and want to know if theres anything I can to to speed up the process
I'm doing this engine swap into my daily driver would it be relible with a CIS system and 280HP
Please someone let me know and thanks the advice
YOSH

Default LoL. Tox's numbers are awesome, but don't be Naive, and think it'd be likely to happen for you...

Toxcheap is the posterchild for doing what people think is impossible... We all praise him for it, myself included. He's found many of the limits of CIS, and is "the" man to talk to about high numbers in CIS.

That said, even he, I believe, will note that if you want "big" power, EFI is going to be the best way to go, taking into consideration $$$, effort, and god knows if you don't have a "great" ability to tune and tweak a car. I think this is true ESPECIALLY if you're swapping a motor into a smaller car. There's simply fewer things necessary with EFI.

If all this is new to you, then tuning CIS to its highest potential is rather unlikely. Want to know more about EFI?

Start at www.034efi.com
Or check out www.motorgeek.com (A forum of VERY knowledgable veterans in the audi-world.

... Not to knock CIS. Toxcheap's cars are so cool I can't stand it. But they've spent YEARS to make Den's wagon be able to eat BPV's. You know?

Default unlikely, really difficult?? why does everyone have such a defeatest attitude?

anything can be learned....start out with a book like "bosch fuel injection & engine management" to get a good understanding of how it works. now this won't tell you how to modify it. but understanding how it works is the first step to knowing what to do. c'mon, it's a mechanical FI system from the 70's.

see the difference between toxcheap and everyone else is that he was willing to put the time in and learn/teach himself something. everybody else just wants a handout... ;-)

Default i hear ya dood....

the thing is if we didn't have EFI, how many 10vT cars would be driving around with highly performing CIS? i don't doubt you might still be the only one...............

Where did you read "Impossible"?? I wrote unlikely, and really difficult... and stand by that.
