All, I've dynoed my big bore combo before, but i finally decided to try a BBK 65mm throttle body. I ported the lid in an attempt to match the dual butterfly's, but I was reluctant to get too agressive due to the IAC path. I dynoed on 8/16. It was 83 degrees at alternative auto (inside the shop) Last time i dynoed there, it was 71 degrees. Lidio said that if I would have waited until the same conditions (regardless of using SAE), I would have seen an additional 5-10rwhp. In my experience, Lidio is usually correct. In short, I made 378rwhp & 366.5 rwtq. I was pretty happy. I'm guessing that if i redyno in cooler weather, i'll see around 380-385rwhp! I'm pretty happy with the numbers. But the TQ curve & peak is what really impresses me... I took the time to make alot of comparisons between pre-big bore & afterwards. I hope you all find this info interesting. If you have any questions, let me know... Chris big bore w/ bbk 65 throttle body Here is the before/after adding the BBK 65mm TB: 305 vs 305 + BBK check out the rest of the mods and comparisons i did at: BlackSnake305
Looks like you gained around 4 peak RWHP and 9 ft ft lbs. Not bad...nice gain across the entire RPM's. Starting to run out of things to do n/a aren't you? So when's the nitrous going on I don't know about picking up 10RWHP with 10 degrees cooler temp on an n/a car though....but I'm no expert. I'm thinking 2-4 RWHP. I'll bet you could hit the 380 mark in the fall.
thanks. as far as nitrous goes, i'd love to, but $1300 bones on juice is not in the cards this year. After i pay off one of my 3 cars, i'm looking to buy a boat. I saw your ride the other day. I'm sure it will be baddazz for sure. couple more days i hear... PS: integrapower on detroit racing: his name is matt and he works in my building. I told him bout your site... hehe
...maybe even today. They were putting fluid in it yesteday hoping to start it before they left for the day...just waiting to hear from Lidio.
Those are some pretty impressive n/a numbers. What compression ratio are you running? Any head or cam work to go along with the big bore?
in my original post, the BlackSnake link is a link to the main Cobra webpage. My next goal is to lighten the car. I'm thinking a Kenne Brown K-member & coilovers...
