[Syty] Would a Sy/Ty do good at...

[Larry Brown]

Thanks for the Reply on PGD (pump gas drags)...I was just wondering how well a syty would do.

Background: Hot Rod Mag sponsors PGD at Memphis with street/strip muscle cars/trucks.
The rules call for invitation-only (300 entries, 75 selections for variety); NHRA rules for speeds you run;
must have all street equipment like workig lights, horn, registration/insurance/license; vehicles must have 
stock or bolt on front  suspension, and weight at least 3,3000 lbs.  Tires no wider than 11.25 ", no wheelie bars;
must pass their tech inspection, & gas is drained and filled with 10 gallons of their 93 octane; power adders
such as water injection can be used, but no other fuel burned. Every competitor must complete a 30 mile
drive. Once at the track each vehicle is allowed a single pass to qualify. Racers
are placed on a sportsman ladder (#1 races #17, #2 races #18...) and run heads up on a pro tree.

On the surface: Cars are DQ for overheating, flat tires, a lack of tire traction (due to cold track and
min tire width restriction & high hp, running quicker than your safety equipment, missing the 30 mile check point,
illegal front suspension. lack of track tuning and such.  Then the pro tree gets alot of drivers as do the 
sportsman ladder system. So the fastest rarely wins, and the slowest get eliminated/beat.

So in the end...the final ten usually are a mix of mid-range vehicles.
Since Syclones could meet the weight, and have awd for traction, and are
very consistent (almost bracket like) they "appear" to have an edge in making the top 10....
if the 93 octane doesnt kill torque, boost, and hp.  With good detonation prevention (maybe some nitrous 
and/or water injection, engine coating, etc) a Syclone/Typhoon might be  a "sleeper".

Not that I plan, have or could participate, but with all of the fast syclone/typhoon vehicles and even the
pikes peak Syclone,  an owner might do good if they had a large tubo`d (or twin turbo`d)
a/c deleted V6 (oddfire or evenfire) or V8 AWD Sy/Ty truck at this event (maybe).  For some
reason none of the Buick guys show up either.

Its probably a wild idea, but I thought it fun to speculate.  I rarely see mention of Sy/Tys at any
sponsored events other than our own syty.net but do know that the Silver State, One-lap of America,
Pikes Peak Race, and some autocrossing events have participants. Maybe its cuz owners dont
know of such events.

oh well...just delete if you find this uninteresting or stupid. I like it when I find a magazine
with a Typhoon or Syclone in it (other than being advertised for sale....lol).

  Right off the bat 10 gallons in a fast SyTy would require a sumped tank.

  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.  
  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. 

  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.  

  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..

    It looks like the Pump Gas Nationals would be a good "candidate" for a fast AWD Syclone, or Typhoon,
    for national exposure (in my head).  But I wonder if 93 octane would be a limiting factor?  The rules state:
    -10 gallons of 93 octane
    -30 mile "driving test"
    -No pre-qualifying at the strip; No posting times for qualifying (to avoid cheating).
    - 11 1/4 inch tire restriction, stock type front suspension, NHRA rules (for posted times)
    - I think a min approx weight of 3300 lbs and a "non-sticky" track was used with a pro tree.

    Now I know some of SyTy owners have fast vehicles, but its my impression that they require
    high boost for max hp.  Does this prevent the use of 93 octane (as they wont allow power adders
    other than water injection), altho nitrous, turbos, prochargers/superchargers are allowed.
    So it appears that really big blocks won in the past, but a small block EFI Camero won this year (a first).

    Just curious (not that I could participate or anything), but it would be neat if a SyTy could
    wind up in the top 10 (in a contest like this).  So would the detonation "factor" prohibit
    SyTy entries...(ie some of the cars/trucks entered ran 10s and 11s, with the 8sec ones
    finding traction problems, and the 9sec ones advancing to the finals).

    I dont know if there is any major prize money, but it appears that they do have several sponsors.
    While the Power Tour and the 1-lap across America draws some SyTy folks, I never see owners
    enter Craft Craft Nat`ls or Pump Gas Drags or such.

    thanks in advance
