<div>Right off the bat 10 gallons in a fast SyTy would require a sumped tank.</div>
<div> </div>
<div>Obviously the lack of high boost would affect the top end of motors, however I wonder how 'slow 'the high 8's, low 9's Sy's would be running with low boost. </div>
<div>How high of boost could they run on 93 octane? 15 psi? 17 psi? As far as I know the really fast Sy aren't running really big boost numbers (They are all under 30psi and closer to 25psi) Engine coatings could help with detonation as well as water injection, thought I suspect most of those truck utilize them already.
</div>
<div> </div>
<div>Even with Vortec and race heads we obvious don't have the best combustion chamber for detonation. Stock Evo's peak at 21psi and settle to 17psi. I think with aftermarket tuns have them peaking 22-23 psi and running 19-20psi on pump gas. They aren't running low timing like a stock SyTy either (14 degree). Fortunately SyTy do a have a relatively good amount of displacememnt for factory turbo motor, however with an endless choice of motor in a compettition like this a turbo LS7 would have a huge advantage.
</div>
<div> </div>
<div>I think one of the fast Sy's could place in the list given the prior times. The only race SyTy is going to kick ass is if the require real full depth street tires and don't allow drage radials..</div>

<div>Howdy </div>
<div>(just received my gift subscription of Hot Rod Mag and they did the Hot Rod Pump Gas Nat`ls writeup)</div>
<div> </div>
<div>It looks like the Pump Gas Nationals would be a good "candidate" for a fast AWD Syclone, or Typhoon,</div>
<div>for national exposure (in my head). But I wonder if 93 octane would be a limiting factor? The rules state:</div>
<div>-10 gallons of 93 octane</div>
<div>-30 mile "driving test"</div>
<div>-No pre-qualifying at the strip; No posting times for qualifying (to avoid cheating).</div>
<div>- 11 1/4 inch tire restriction, stock type front suspension, NHRA rules (for posted times)</div>
<div>- I think a min approx weight of 3300 lbs and a "non-sticky" track was used with a pro tree.</div>
<div> </div>
<div>Now I know some of SyTy owners have fast vehicles, but its my impression that they require</div>
<div>high boost for max hp. Does this prevent the use of 93 octane (as they wont allow power adders</div>
<div>other than water injection), altho nitrous, turbos, prochargers/superchargers are allowed.</div>
<div>So it appears that really big blocks won in the past, but a small block EFI Camero won this year (a first).</div>
<div> </div>
<div>Just curious (not that I could participate or anything), but it would be neat if a SyTy could</div>
<div>wind up in the top 10 (in a contest like this). So would the detonation "factor" prohibit</div>
<div>SyTy entries...(ie some of the cars/trucks entered ran 10s and 11s, with the 8sec ones</div>
<div>finding traction problems, and the 9sec ones advancing to the finals).</div>
<div> </div>
<div>I dont know if there is any major prize money, but it appears that they do have several sponsors.</div>
<div>While the Power Tour and the 1-lap across America draws some SyTy folks, I never see owners</div>
<div>enter Craft Craft Nat`ls or Pump Gas Drags or such.</div>
<div> </div>
<div>thanks in advance</div>
