1. GTXVette. I sent a PM to you earlier apologizing for any rude or out of line comment. While I don't recall even approaching something rude to anyone, I am not about to say it did not occur. I will say I do not recall. And, have had to apologize for things most of my adult life because my intent and impact don't always align. 6 days ago I was informed that I wrote something offensive and hurtful. I reread it 3 times in the tone in which I meant it and wrote it, and I couldn't see the errors of my statement. I then reread it in a negative tone an could see the offendees point of view. I apologized to that person and I sincerely apologize to you. Please reply to my PM and let me know what I said. The board is not the place for these details.
2. We are building cars with $2017. We are not building $2017 cars.
3. $100 car was not only the price, it was the delivered price. Those cars are available in our area. We walked away from a 72 240Z 2-3 weeks ago for $200 and it was/is in better shape then the one we used in this build. I bought a 75 280Z for $49.95 off eBay. We learned early on that one of the keys to the Challenge is buying a cheap car that can be sold down to zero. If you start high, you may or may not zero the car, and you definitely limit your parts sales. To date, our most expensive car used for a Challenge platform was $300.
4. Use your own on line calculator, I have my own calculations. Our car went 10.4+ at 130 with no nitrous. It weights 2,455# minus a few parts I removed before the event (probably 7#). Basic numbers for HP is 392 to 418, depending on which calculator you use. Are folks not able to build cheap SBCs to make that kind of power? I don't think there is too much heartburn with that. Admittedly, we do have an over abundance of SBC parts available since we are in the middle of dirt track and drag racing tracks. Then add the Power Shot Nitrous that got sprayed gate to gate. NOS claims 150 HP, we consistantly see 160-170 HP. I do tune the system with fuel pressure to better match the cylinder weight and don't rely on the the single setting in the instructions. 150 HP should be a 0.9 second improvement. We saw/see/ran 0.89. Final HP numbers are 526 to 544 on spray. Are there any parts or pieces in question?
5. We tested and tested and tested. We changed parts to match an ET event, not a MPH event. We adjusted launch rpms, shift rpms, gear ratios, timing. Did I mention we tested and tested and tested?
6. One of the single most important items that must be employed when building a Challenge car is this.... $20 is 1% of your budget. Is that part worth 1% of your build? Is that $40 part worth 2%? When you look at the smalls and make/build/account for the small expenses, the bigger parts are more attainable and/or attractive for a budget build.
7. Cars with straight line set-ups don't turn (our car). Cars with turning set-ups don't launch. There are exceptions. Ed's $2014 Mustang and our $2015 Bug. The difference, they were easily convertible from one discipline to the other. I picked my poison and knew it was a one trick pony. That alone was/is/could be 1/2-2 seconds in the drags, but 2-3 seconds in Ax.
