    How much what?

    Preliminary Number from Project 2VNA-10

    There was minor work chambers, swirl damns are in place. I'm running CP flat tops with valve reliefs. Compression is in the 12 - 12.5:1 range. Thanks everyone for support, I can't wait to hit the track!

    Preliminary Number from Project 2VNA-10

    Thanks everyone. This engine should see significantly higher RPMs once the new P51 goes on. Ken

    Preliminary Number from Project 2VNA-10

    That's a good question on the crank. The reason that I used the GT crank is because it's lighter it's cheaper and this is a project car and we thought we would test just how good the GT crank is. I think alot of people are wasting there money on a Cobra crank. How many have had a GT...

    Preliminary Number from Project 2VNA-10

    I believe in a few weeks. The first guy on the list is here in Cincinnati and is getting it installed and tuned here so keep an eye out for results. Ken

    Preliminary Number from Project 2VNA-10

    10's probaby wouldn't happen with those numbers, that's why it says preliminary;) Tune is very safe, and once the P51 Race intake goes on, I should see a significant increase in power. Best on the old combo which is the other graph is 11.72 Ken

    Preliminary Number from Project 2VNA-10

    The baseline numbers are in on the new combo. The goal of this project is 10's 2VNA with a 4.6L (No big bore or stroker). The engine was built with high RPM's in mind and will get the Fox Lake P51 race intake when it's ready. Keep in mind, this is NOT a high dollar project. We tried to keep the...

    question about a chip

    Where did you read this exactly? That's not true, we have done hundreds of automatic tunes just this year and we have never had a problem with increasing the line pressure. Ken

    How does a chip maintain a different A/F than the stock stoichiometric ratio of 14.7?

    That has absolutely nothing to do with what we are talking about. I assume you are talking about controlling open loop via widebands. Bad idea IMO. Either way, you're confusing the topic. I'm talking about how the stock EEC works, and how a tune recalibrates the EEC but doesn't change how it...

    How does a chip maintain a different A/F than the stock stoichiometric ratio of 14.7?

    Yes Yes there is a link. But there are some changes that can make the learning better and if done correctly, you will not run into any problems. It doesn't work exactly how you describe. While in closed loop, it comes up with correction factors (fuel trims) which are percentages. So since...

    How does a chip maintain a different A/F than the stock stoichiometric ratio of 14.7?

    I'll try and explain it a little better There are two 'modes' you can be in, open loop and closed loop. Closed Loop The EEC uses the front O2 sensors as feedback to maintain 14.64:1 Air Fuel Ratio. This is generally at idle/part throttle situations. Open Loop The EEC doesn't use the...

    How does a chip maintain a different A/F than the stock stoichiometric ratio of 14.7?

    Didn't I already explain this to you? If you didn't get it, tell me why and I'll try and do a better job. It's really not that complicated. Ken

    Is there any way to adjust fuel pressure on 99+ (returnless) cars?

    Just an A/f bump? probably not. But a complete tune should help out a bit. The advatange a tune gives you over a timing adjuster is control of the timing throughout the RPM range. Much better than a base timing bump. Ken

    Is there any way to adjust fuel pressure on 99+ (returnless) cars?

    Nope, no way to do it without a chip/flash

    Matherly won :flag:

    First 2VNA with stock heads in the 11's!

    Looks like Matherly was holding back! He took out Lawrence in the second round! 2. T Matherly .081 9.770 138.74** 5. R Lawrence .083 9.867 139.18

    First 2VNA with stock heads in the 11's!

    Congrats again to Bill for coming so close to taking out defending Mod Muscle champ Lupe Davila in the second round. Look like a .06 margin of victory. I guess the Modular Depot sticker on Bill's car scared Lupe after losing to AutomaticWeapon (Mike Bowen) in Bradenton in the first round:)...

    First 2VNA with stock heads in the 11's!

    Congratulations to Bill Putnam! Bill just ran an 11.97@113 in the first round of eliminations at NMRA Reynolds! Bill is the first 2VNA car with stock heads to run an 11. Here are his mods: VT Engine Stage 1 cams, MAC Longtubes, Bullitt intake, VRS Shorty X pipe, Dynomax Bullet mufflers...

    EFI Solutions or Custom Chip?

    Actually the PCMX has been around for a long time and Tim said he himself that he licensed it. Are you suggesting that the software that EFI uses was not developed until after a contract was signed? I was under the impression, and correct me if I'm wrong, that Tim used the PCMX to start with and...

    EFI Solutions or Custom Chip?

    Actually Tim, in this thread ( http://forums.modulardepot.com/showthread.php?s=&threadid=4038 ) you said: Just wanted to point that out in case you forgot. I would hate for you to correct Pro-M and have someone bring this up latter so I figured I would point it out now.
