yes i am aware of this. i was up to date on his postings of building the car. nothign wrong with what he did. but its still more money spent. as far as hp gained with pistons and rods, i don't know if there is any gain.

 

Why did you only raise it to 7800? Wouldnt it have been better to go higher for the "just in case" 200 more rpm is not enough? How long are you actually bouncing off the revlimiter before crossing the 1/4?

 

Yeah, that was actually an oversight on my part. In preparing for the flash, I had considered asking for an 8000rpm limit, but when Al was actually sitting in the car doing it, I completely forgot to ask for it. It may come back to haunt me, but I will at least get that 200rpm buffer, which should be good for another 2mph or so (enough to drop from 12.01 to 11.99?). Another thing was that I was worried about revving to 8000rpm in 4th without any headwork. I know others have done it, but it's not really something I'd like to risk. 7800 is within my personal comfort zone, so I think I'm ok.

It's hard to say how far out I am when I hit the rev limiter. It's a significant enough distance that the it hits the limiter 5-7 times before I cross the line. On my 12.01 run, it was so drastic that I went from reeling in the Camaro next to me who ran 11.89 at 113 to me falling back immediately. It was the first time I had a car in front of me that was really close when hitting the rev limiter, and it gave me a better idea of how much hitting the rev limiter is affecting me.

Basically, on my next run, if I STILL hit the rev limiter before the traps, I will know that I was hauling ***, because it would mean I'm hitting 113+ before hitting the rev limiter, which is still before hitting the traps. It means I'm making great power that is not completely dying off at the top of 4th despite no cams. Depending on what happens, I may need to get it raised to 8k after this weekend. I think Al would do that for me...

 

Gotcha, if it helps ease your mind at all, I'm running the 280s with stock springs and retainers for the past 8 months with no worries at an 8200 rpm rev limit. My car lives in 7-8k territory.

 

you have proven to me clayton that the 10.5 is far superior than the 9.8 i have. I put down 351whp with everythign you have plus cams and cam gears. i do however have 375wtq. i think its absolutely amazing what you have done.
the stock head will hold 8000rpm, i know because i did

 

good launch

 

I'm not so sure, Liam. I only dyno'd 294/270 with these mods. On race gas, I'm probably around 340/330 at best. If you add cams to my car on 93oct, I'd only be in the 320-330whp range in both whp and torque (more torque from the new flash). I can't imagine even getting CLOSE to 375wtq. Where did you get those dyno figures? That torque is insane...

Perhaps I will send my ECU to Al to get that 8000rpm limit after all...

 

you are easily 330whp on 104 octane which you'be been using (i think) remember i used 110 to get my numbers. i suspect you would easily trounce my 350 number with cams and 110. you are already pretty close to that with no cams and lower octane
my dyno was on pruven's dyno up in CT. as you remember thats where i'm from and where Al is from. I think my whole torque issue has everything to do with my cam gear settings

 

Yep, the new 05's are doing way better than I did stock. Maybe if I can convince someone to buy a gt35 then I can steal their 10.5 turbo

 

Oh, I thought your dyno numbers were on pump gas. Oops. No wonder...

The confusion with my octane is that I calculate the octane based off the mix I use. I have yet to use straight race gas in any of my trips to the track, because I don't carry the things I need for draining the pump gas out. Each time, I just end up mixing the available race gas with whatever is in my tank. For the 12.01, I had 4gals of 110 mixed with about 2gals of 93, which equals to 6gals of 104. So, I was actually using 110oct, but it wasn't pure race gas. Still, though, I agree that I'd probably be closer to 370/370 on full race gas with cams...

 

I had maybe a gallon of 93 when i dumped in 5gal of 110 for my dyno. its too bad my tranny took a crap after that. i would have really liked to get a good run with her.
on my first pass with those numbers i couldn't hit any gears at all. i'd go to shift and it wouldnt' go it so i'd have to wait then try again. my best run was 13.1@111 and she was pulling like mad...and that was on a 1.66. i do need to get new tires as i'm spinnign way too much and getting sideways out of the hole... still pulling mid 1.6s
