sir camel toe Posted July 2, 2004 Share Posted July 2, 2004 hi chaps how can i make my car lighter its se 1700 crossflow plus what cams do u guys use. on 40s at mo but upgrading to 45 throttle boddies soon. any info would be a great help.cheers Quote Link to comment Share on other sites More sharing options...
felters Posted July 2, 2004 Share Posted July 2, 2004 Just chuck everything out that isn't necessary. I don't have seats, interior, windscreen, boot box, heater. I do have c/fibre dash, boot cover, 13" K&N rims... No idea what it weighs but it's a narrow car with a 4AGE engine - cant be much. More aero dynamic without the screen as well.

Blatman Posted July 2, 2004 Share Posted July 2, 2004 45 throttle bodies may be too large. Remember that throttle bodies don't need to be as large as the carbs they replace, so choose carefully. As for lightening, just as Felters says, chuck everything you don't *need* overboard..... Quote Link to comment Share on other sites More sharing options...
the bear Posted July 2, 2004 Share Posted July 2, 2004 I have it on good authority (ex racer) that even Carb 45's would be a waste as the 40's are perfect. I also run a 1700 xflow. Also get a copy of track and race cars for last month. They did a review on TB's and although the top end improved the bottom end torque suffered. (jeez I almost sound like I know what I am talking about) My man reckons X flow all the time over a pinto or a Zetec as the engine has better torque and revs better. He seems to know cos at the time I was waiving a wedge of cash at him and he advised sticking with the xflow and getting it fixed (it aint well! ) over replacing the engine. Still if you cant be persuaded and the 40's are Dellortos or Webers I might be interested in releiving you of them. Quote Link to comment Share on other sites More sharing options...
Blatman Posted July 2, 2004 Share Posted July 2, 2004 Mr Bear. Let me apologise in advance...... My man reckons X flow all the time over a pinto or a Zetec I fear your man may have a vested interest in x-flows. The volumetric efficiency of a 16 valve Zetec means that it'll p*** all over a x-flow for torque and power, if like for like engines are compared. So, whilst Nob Ravins X-flow may well have the licking of lots of Zeteces, when a Zetec is prepped to the same "full race" spec, the Zetec will again be more powerful, and more torquey. 45's, and even 48 carbs do have their place on the appropriate x-flow, but again, they'd be pretty extreme examples. For most road/fast road applications, the 40's will be fine. Lastly, drivability with throttle bodies should again be vastly superior to carbs. If they aren't, then there is a fundamental problem with the bodies/map/ecu. Quote Link to comment Share on other sites More sharing options...
oldman Posted July 2, 2004 Share Posted July 2, 2004 Weve had this before..but here goes..

Blatman Posted July 2, 2004 Share Posted July 2, 2004 The comparative volumetric efficiencies are discussed here. Take careful note of what Peter Carmichael, and AMMO have to say on the matter.

Mrs Westy Posted July 2, 2004 Share Posted July 2, 2004 Try and ignore some of the off topic rambling.... Should be easy enough to do. We have enough practice round here Quote Link to comment Share on other sites More sharing options...
Blatman Posted July 2, 2004 Share Posted July 2, 2004 True, but with Sir camel Toe only having 5 posts, he may not be quite up to speed yet..... (pun intended, BTW) Quote Link to comment Share on other sites More sharing options...
the bear Posted July 2, 2004 Share Posted July 2, 2004 I understand where you are coming from Blatters, I agree he is def old school and loves x flows, in the end cos I dont really know how to do any of it myself I have got to trust someone, and so far he has taken no money off me for work done weeks ago cos he feels the car isnt right yet. As I intend to do Speed Series next year for my own enjoyment I am going to need someone who knows his way around an engine, this guy is local and geniune with a good reputation and lets be honest, I aint going be able to realise the potential of my car for a few years coming into this as someone who has never driven on a track. I think you agree with him that 45's are not going to help a xflow. He def doesnt like Zetecs, Quote Link to comment Share on other sites More sharing options...
sir camel toe Posted July 2, 2004 Author Share Posted July 2, 2004 cheers for the advice just got the tbs sitting in the shed been told at my local meets that they would be all right with cams plus head work Quote Link to comment Share on other sites More sharing options...
Rob Navin Posted July 2, 2004 Share Posted July 2, 2004 So, whilst Nob Ravins X-flow may well have the licking of lots of Zeteces, when a Zetec is prepped to the same "full race" spec, the Zetec will again be more powerful, and more torquey Blatters I have just had a look here to see how far you can go with comparing my x-flow against a top spec zetec. I have used the carb engine as that is what mine is running. I know its not a fair assesment because my car is only 1700cc and the zetec listed is 2000cc. I have to admit I am not as worried as I should be about these figures IF this is the most you can go to without carbs. Has any one got more out of the zetec without going TB's and have you any idea what a 1800 engine would be producing ? Not wanting to start a mines bigger than yours thread I am genuinly intrested in seeing some actual results Quote Link to comment Share on other sites More sharing options...
