what he said ^^^  :D


fabr , did i tell you while talking to carl it dawned on me what was wrong with my busa engne all that time??   


i case i did not, ( still a bit painful to talk about lol ) so in a nutshell i forgot to re caliberate my gear position switch in bazzaz.  as you well know and i'm sure others know, the stock ecu has gear specific fuel/timing maps for set tps or map readings. N has its own fuel/timing map. part of a big push back when was a resistor that went inline with the gps ( gear pos sensor) to tell it that it was 5 gear to cancel the speed limiter plus more power in lower gears depending  etc etc .   so bazzaz has some default setting that isnt correct and i saw that before i shipped mine back.  it had a couple bad connections and bazzaz there there was an issue in a couple runs of harness's. i forgot to recaliberate it when i got it back. basically i was stuck in N map for most of the gears.

Turbo it to around 300 safe HP. What's your car weigh? Maybe 7-800 pounds? Using 800 pounds and 300 HP makes itapprox 2.7 pounds per HP(OR 700 pound car would be just 2.3 pounds per hP). Consider a 3500 pound car with twin turbo'd v-8 making approx 1200 HP.That would be 2.9 pounds per HP. The smaller car wins out!!! GO for it!

 I was watching some vids of the HP Wars in Glamis a couple years ago. The TomPro turbo busa car was barely,just barely,being out run by the really big HP dogs. You know,the 2000+HP guys. Honestly why pay $$$$$$$$$$$$$$ for a big HP car when you can have the same perf for $$ with a busa?????? The ONLY thing the big cars can do better is hammer the terrain when a small car can't.

GOnna look killer when done!Turbo the thing and you will have no problem running with most of the big(hp) cars.

Hi KathleenBarnes,

Tell us a bit about yourself?

Any cool projects on tap?  Prior experience?  

Do you have the winning lotto numbers?

The rear hubs are a 5 on 4.5.  I have adapters to run the 4 on 156 bolt pattern RZR wheels.

Here is a booty shot.

the stretched rear section really does change the overall look, i do like it.  the boxed and plated lowers is probably the best idea.  what bolt pattern are those rear hubs?

That makes perfect sense.  I went back and reviewed pictures of other a-arm suspensions and the truss goes all the way to the reaction point.  I will use these arms for set up and I think I will build a set of boxed plate lowers.  I would rather be safe than sorry.

I appreciate the info!

It'll just bend at the end of the truss.   You're just moving the stress point.  To overcome it with a truss the truss has to go from one reaction (think pivot) point to the other.  At which point why even use the tube other than be a jig for the truss.  The shock in the middle of the arm is the problem......

Putting the shock on one side and the bypass on the other is a good idea to balance the load but the arm will still see twist if they are not even in the reaction force when the arm is forced up in suspension compression.  Whether it's close enough???  all you can do is try it.
I agree with that.
