^^^ Nope because we will add back our Hp-to-Weight Ratio. The only reason we dropped it was we didn’t think it was necessary at this time.

As far as I know none of the car that ran the Nationals had blueprinted engines? Ted do you know some thing the rest of us should know? Chris's SVT made very good power and he still can put a tune on it.

Please also remember that the series is still very young, so changes to formula used for power - whether RPM limits, HP/TQ/WT, etc - are bound to change. Part of the factor is that it's not easy to tell who can get what power out of which motor within the scope of the rules. If racer's start to build (for example - SVT guys stay chilled) blueprinted SVT motors that consistently make 170, then they will have moved the benchmark for what that motor is evaluated on - and therefore other factors will be adjusted to compensate. i.e the assumption would then be that all SVT motors are capable of 170.

For example - the 2.3's proved to be the fastest in 2007, so they were reined in for 2008 by increased weight and limiting R/P to 3.82.

Also, - if someone is making far too much power, NASA has the right to claim the motor if they so choose.

We increased the weight to all 2.0 cars, mainly because it made it harder for the Sedans to get down to 2575lbs. But the 2.3L is still 75lbs heavier then all the 2.0L

2575 was the previous minimum weight. It was too difficult for the sedans to get to that weight, so they raised the minimum weight for all cars up to 2600. Because they felt the 2.3 had an advantage, they raised the weight of those cars even higher.

Is there anywhere that I can follow a guide line to what meet tech inspection? I know in some places you need to vent the battery box to the outside of the car. I just want to get that right if I decide on doing so. Also what about mounting it. I would probably go with a battery box that would be strapped down to the car but I haven't look to deep into this.

We've used the Moroso sealed box in the past.

Default Re: 2008 Spec Focus Rules

In NASA CCRs it states the following.

18.8 Battery
The battery shall be securely fastened down to the car. No Bungee cords or rubber cords may be used to function as the sole hold down mechanism. An electrically nonconductive material must cover the positive battery terminal. Any battery located inside the driver’s compartment shall be fully covered and firmly secured to the chassis in a marine type battery case. True dry cell batteries may be mounted without a surrounding case, however a case is still recommended. Note- there is a difference between “dry cells” and “gel cells.” Gel cells still need to be mounted in a case.

No Optima are SpiralCell Technology. But, they are still acid filled cells. The Dry cells are like the Odyssesy Race Batteries.

Hey guys sorry for asking so much but is there any rule that would not permit a balance shaft delete on 2.3L duratec? I really wouldn't know under what that would fall because I don't think it is part of flywheel but then again there probably is a rule not permitting me to do so.

Default Re: 2008 Spec Focus Rules

To answer my own question I gues this rule would eliminate the balance shaft delete.

11.2 Balanced and Blueprinted Engines
Engines may be balanced and/or blueprinted. Lightning of parts beyond what is necessary to balance is
prohibited. Only the minimum of material should be removed from any engine component during a rebuild
process.

The RPM limits for the SVT Motors have been changed from 7,000 to 7,400 rpms.

The following RPM limits shall apply:
• Duratec 2.3 6800 rpm

Clarifications to rule 6.1.2 Engine/Transmission.

I have received an email and also replayed to a post in the NASA forums about Mazda Engines.

Currently under the 2008 Spec Focus Rules only Ford Duratec, Zetec, and SVT motors can be used. Mazda MZR 23 and MZR 20s are not allowed. Also Euro Duratec Motors and ECUs is not allowed as well.

Re: Technical Bulletin 2008
Ted7rns

In the rules where it states OEM, that means US Market OEM items. Not Euro OEM.


Re: Technical Bulletin 2008
Matt Marks

Theres a note in the rules (Section 6.1) which states that "all parts, unless otherwise noted, must be from US or Canadian models in mass production, and must be commonly available." So I think you have this covered.
