  1. Haha. I would prefer to question nothing (so long as there is nothing dishonest happening) and just acknowledge that they are fast.
  2. It is a light, and why would you care? It should be light. It is a race car. Obviously, it helps it be fast. It is still fast. Do people get pissy with racers calling their car a full weight street car when they are running race full and the car is clearly not roadworthy (legally)?
  3. Is this car on the net somewhere?
  4. Irrespective of what it weighs, it is fast. Good to see another fast 250.
  5. I doubt it, but yeah a straighter port must be of benifit. Do you have examples of the Cleveland heads that have been chopped to achieve this?
  6. Manual valvebody in an auto you get engine braking too, so they also work for corners.
  7. Sounds like he also wanted your rockers and springs. Mind you, if it had a stock cam, I tend to agree with what he said. It must not have been std. Hurricane do make decent extractors too.
  8. Pulley/balancer setup looks way better post mod. Do you need the v-pulley? Your crank will like you if you can take it off and have less hanging off of the front and the s/c pulling closer to the block.
  9. I also agree that you likely have at least 5deg too much base timing at the moment. You can set this for what the car likes at idle and use your ramp to get to where you need to be at total. ***** Sorry, I missed that you have already pulled it back to 15 degs.
  10. Yeah, ok. You might be able to bring it in sooner though?
  11. I agree with what Greg has said, but I also say do it. And the argument for getting this rather than paying someone to tune a carb is the same as having programmable ignition rather than getting a re-graphed dizzy (i.e. you change something and you don't need to pay again). It also means you don't need to take it somewhere and talk to someone, haha. That last vid it goes pretty lean on transition though.
  12. I would have thought more than 2 deg/500rpm? At 14deg idle (and upto 900rpm to stop the timing wandering at idle), that is less than 25deg total at 3,200rpm (where I would be thinking more like 32-34deg. This would be my total advance guess (i.e. 32-34deg at 3,000-3,200rpm). In saying this 2deg/500rpm might be a good starting point and ramp it up progressively from there.
  13. How much boost can these things handle?
  14. Almost, yeah. Nice clean and bright headlights (like new factory XE lights) for me. But then again, I like XFs so WTF would I know, haha.
  15. Rev it as much as you are comfortable with. The guys that want to see 6,000rpm before everything is sorted can build their own. Once you have a good power run under your belt and see it working to 6k, then you might use it.
  16. Yeah, stiffer, but not as stiff as new lows still.
  17. Cutting springs makes the spring rate higher, not lower. Just buy some lows.
  18. You could try one of these which are designed partly to reduce losses due to sudden expansion: https://www.summitracing.com/int/search/product-line/wilson-manifolds-tapered-carburetor-spacers
  19. I was thinking more like this (although the runners are long): http://www.myrideisme.com/Blog/cam-design-guide-for-weber-carbs/weber_intake/ What you have done, certainly looks the part though.
  20. xFalcon thread "BA AU Upgraded XE THE BOSS" I think KLR250 was using BA stuff in the front of his XF too?
  21. I am sure it could be, but as you say, a custom manifold would be required. I would probably have one fab'ed up rather than using the banana manifold. A nice row of carbs sticking through the bonnet would look cool if nothing else.
  22. Downdaughts would be cool, no tower clearance issues then.
  23. Yeah, fair enough.
  24. Or keep a clutch fan because there was never anything wrong with them...
