DEV Kits

I was just curious to see if anyone has had the DEV5 kit put into their car. I was just reading up on the two variations of the DEV5 kit, and saw the power output of the DEV5 (170rwkw) and the DEV5 with an aftermarket computer (175rwkw) - can't remember its kit number.

From memory, the price difference was around $800 more for the one with the computer.

Can anyone justify the extra 5-odd kilowatt gain for the extra $800??

Are there any benifits of having the more expensive one?

Re: DEV Kits

I have a dev5a cam in my car, Im just waiting for the head work, which should hopefully be finished by the end of august. so far it goes real nice but it is a bit sluggish off the line, so diff gears have hopefully fixed that.

Go for it why not you will only regret it later.

Re: DEV Kits

I have the DEV5 kit and it is nothing short of excellent.
Smooth power delivery, easy starts, good fuel economy.
Power below 2000rpm is basically like a standard engine - between 2000rpm and 4000rpm it is quite a bit stronger with a nice urgency - and above 4500 it surges like a warmed over big capacity V8 all the way to it's 5800rpm redline.

I don't know how much difference there is with the DEV5A kit, but I doubt you'd be missing much.

From what I've read, the DEV5A idles quite rough, where as my DEV5 idles like a pussy cat. Close to standard, with a slight lope.

What's that?..... Did I hear you say TQE power?

That's what it says in the 'Promise delivered' article on the JMM website.
And of course it would idle rougher, it has bigger cam.

Re: DEV Kits

Thanks for all the replies. I didn't think any one could justify the $1400 price difference (DEV5 - DEV5a).

Re: DEV Kits

Well you do get to the point where the gains are smaller and the dollars are bigger when modding your engine and then its time to consider what you really want to do.

Sell and buy a faster car to start with.
Put a bigger engine in.
Put a turbo or supercharger on.

All of these are $10,000 dollar questions
