if you plant the car in the wall, dead on hard it will bend just behind the front bumper before the front bearing blocks, break the radio tray, exact same on both pro and 705
705 stays stiffer in your hands( ie less flex in the motor area due to the new stiffiners, but this make no real world advantage as it takes a ton of force to flex a pro( and i never use any aluminum x braces or stuff like that, just the stiffiners)
Very complete observation and comparison One of the things I noted were that in the 705, they are now using Veteq springs like what Ralph did to his Impulse PRO at the Nats last year The rear springs are a little longer and I feel that they perform better than the old ones.

Thanks for the info. As for other 705s beating me, I'm the only with a Serpent here. We've a couple MTX3s, lots of NTC3s, a few VoneRRs, a couple of RS4s and 3s
As for my Impulse its the Streetspec had converted to Pro. But now, I took off the shock towers and put back on the Top radio tray. To me it handles better.
Is the 705 lighter than the Pro?

I ran my pro drivetrain in the 705 as i felt it was lighter and free,( very well massaged and broken in) as far as drive train they are identical, i was still using pins on all the pulleys until worlds when i switched to the hollow front shaft, which made no real diff in cinn, just made me feel better, and i ran the pin brake and side pulleys even on the hollow rear shaft untill winternats, i almost never seek lightweight and or special parts, they are usually a waste of money to the average guy, until maybe the last big race or two did i become comfortable on the stand and start to race like i was on a local track, and have a bunch of fun..

oh the springs in the box were identical, in the one i got two weeks ago???
the main diff in the cars is the chassie bracing, tank and battery placement...

her is me in ft myers

here is a pic of the track by the driverstand, looknig through pit row, this track was a lot of fun to drive if you did it right if you were wrong, well not as much fun, i can say it is probably one of the best tracks i have enjoye drivig, my favorite part of the track was the carousel, i could pass three or four cars in trafiic on the inside line... a foot off the entrance and you could lose 8 feet in the corner.... it was a blast to

Nice pics Andrew. Glad to know you enjoyed racing there...

Anyway, for me, I know it made a difference in the belts and they way the car rolled when I changed to the new 705 pulleys in my PRO. The front belt last longer and the car rolls smoother. The new styled pullys eliminate play usually associated with pin styled mounts. Even the MTX-3 changed to the same style grub screw aluminum adapter pulley mountings... There must be something good here...

And as for the springs, look carefully. The part number given for the 705 yellow spring is 901415. This is a VETEQ spring as with other options of the white, red and blue springs. The yellow spring found in the PRO is 909415.

I believe in terms of static mass, the 705 is slightly lighter with all the carbon side stiffeners compared to the PRO with aluminum side stiffeners etc.

Rotating mass is much reduced on the 705 due to the new 2 speed gearbox. That is the most important thing to look for.

Whatever it is, keep the Serpent flame burning in Hawaii, Roy

no i agree the grub screw stuff is much better. but not faster, the lighter two speed is a plus, rotating mass is were you want to remove it.. both my pro and the 705 weighed in about the same, just about illegal.. hmm i will look closer, never ran the ones that came with it..
