Zetec Se Spitfire With Eaton Super Charger....


Recommended Posts

Ah, but I bet that supercharger gives a MUCH flatter/better torque curve. 

And may not have cost as much as your setup. People seem to do forced induction for very reasonable money.

 

Actually as a package that looks a good deal at the moment. Gearbox is £200+ worth....

Not clear if the megasquirt is included. If it is that package is a steal!

I see what you mean because I have throttle bodies and cams. Probably cost a touch less but my torque curve is awesome. Looks like he went a long way round to get the same result. Don't forget the extra weight he will have added. Shame too as if he had done it right he wouldn't be wanting more or a different engine. Toby can a test to that. The sellers car looks very nice too, infact come to think of it I think low down torque would actually be a bad thing as mine wheels spins on full throttle. Its hard to explain to people how quick it is till you try it. However if you cut corners or try to do things differently and cheaper you just don't get the same result as if you had spent a little more. I try to tell people this who buy my kits but sometimes you talking to a brick wall. I know not everyone wants performance but they would be lieing if they told you the stock power was ok.

 

Just for reference.

The "if he'd done it right the first time" comment is a bit harsh! We're all proud of what we've done with our own particular projects and choose certain ways of doing things for reasons that suit us.

 

Yours looks like a really well sorted car, that does what it's supposed to and is getting appropriate use by the looks of things. FWIW though, that engine with a positive displacement blower will have masses more low down torque than a naturally aspirated one - regardless of cams etc. The weight penalty is likely to be about 20kgs - half a tank of fuel or so?

 

Whether more is necessary / desirable is just a personal take on things.

 

Good on him I say, the more the merrier, it'd be interesting to see what he's putting in there now to make it quicker still.

It says he is going Duratec, which depending on CC might not be too much different to what he has now minus the charger. 

 

However you say he will have masses more torque than the normal motor but I disagree. He has decompressed the engine with a plate. I've seen many like this, a company use to do them but only 160bhp was achieved with the same results as well designed cams because of the comp drop etc. Maybe thats why hes changing the motor as he has hit the max possible with his current setup. Another thing to note is if you go crazy with the torque then you risk snapping axles on the long shaft cars.

NA duratecs can (and do) achieve well over 300bhp when built correctly. I know a local escort with about 325 bhp yomping about the area,in a very light shell :o

These are not BS figures, they are from engine dynos, not rolling roads, so no tweeking can happen.

I believe they are also being developed for the  rallycross championships. They currently use YB engines, but they are getting VERY expensive (about £60k for a fully built/prepped unit ready to fit).

Expect the duratecs to be around 650bhp on a restricted (by regulations) intake. 

 

I think the decomp plate is the cheap alternative to low compression pistons. Forced induction needs reduced compression for anything except very low boost.

That engine could turn the boost up, and get more power and torque. However, it may have been set at a sensible level to prevent breakages.....

 

As to breaking things, diffs, would be my biggest worry, then gearboxes and finally shafts. The T9 will be near its limit with that ebay engine  torque I reckon.

I agree, most of the parts will be at there max tolerance level. On another thought, I've seen a Zetec SE with a turbo putting out 450bhp in a caterham. He said it was too crazy so detuned it to 250bhp. This was a very expensive engine and was very well done. I just think the above setup is very home brew and I would have got better results leaving some design aspects to the pro's. Don't get me wrong I'm all game for doing stuff yourself but to get the better results you sometimes need to look at the type of engine you have and get the better designed parts which cost more. The Zetec SE thrives on Higher rev's. So why would you add something that is better suited to low end power???Martin on here did the same with the mazda unit and was disappointed with the results. He then switched to a turbo but he still sold the car in the end so maybe other issues were involved or maybe he just had enough. I think we have all been there with these cars.
