letitsnow Posted April 22, 2012 Share Posted April 22, 2012 (edited) Ok, maybe not just, but friday. I figured I'd post the sheet because I don't see many positive results. Boost was ~17psi at peak torque and a linear taper down to 10psi at redline, we're pretty sure the T3 is out of air. This is corrected for atmospheric conditions, observed power was 250hp/320tq. On other runs we did go to 6k and power remained almost completely flat.

madkaw Posted April 22, 2012 Share Posted April 22, 2012 Nice numbers for a basically stock 280ET with good engine management-excellent! Quote Link to comment Share on other sites More sharing options...
Leon Posted April 23, 2012 Share Posted April 23, 2012 Nice, must be a fun car to drive with all that torque! Quote Link to comment Share on other sites More sharing options...
1 tuff z Posted April 23, 2012 Share Posted April 23, 2012 Nice numbers-which shop did the dyno? Quote Link to comment Share on other sites More sharing options...
letitsnow Posted April 23, 2012 Author Share Posted April 23, 2012 Rick Gifford(also known as Bald turbo freak) in honeoye did the tuning. The car is a blast, I autocrossed it today and it did great, the huge torque did make things a little tricky, the rain didn't help either. A couple times I wanted a bit of power and got a ton, but it's still very manageable. Quote Link to comment Share on other sites More sharing options...

1 tuff z Posted April 23, 2012 Share Posted April 23, 2012 Rick did the mods to my right long tube ss LSx header a few weeks ago-post #322 here. So when do I get to see the z and where was / what group the auto-x yesterday? David Rick Gifford(also known as Bald turbo freak) in honeoye did the tuning.

letitsnow Posted April 23, 2012 Author Share Posted April 23, 2012 The autocross was held by FLR SCCA at RIT. I'm planning on running the season, and maybe a few BMWCCA or WNY SCCA events if you want to come out to one of those. I still haven't got that bumper on yet, it's still sitting inside waiting. I need a fuel tank if you know of one for a '77 sitting somewhere. Quote Link to comment Share on other sites More sharing options...
Mack Posted April 23, 2012 Share Posted April 23, 2012 good to know there are still a few "datsons" out there making decent numbers! Very nice! Quote Link to comment Share on other sites More sharing options...

joker81 Posted April 24, 2012 Share Posted April 24, 2012 nice numbers!! hope to produce something like that soon. Quote Link to comment Share on other sites More sharing options...
JacktheRiffer Posted April 26, 2012 Share Posted April 26, 2012 Whats your 0-60 like? Quote Link to comment Share on other sites More sharing options...
letitsnow Posted April 26, 2012 Author Share Posted April 26, 2012 Pretty quick? Haven't measured, it should run mid 12's in the 1/4 at 108-110ish. I ran 13.4 at 101 on roughly 80hp less, 8.6sec to 81mph in the 1/8. Quote Link to comment Share on other sites More sharing options...
Mikelly Posted April 26, 2012 Share Posted April 26, 2012 Very nice... That's a very solid and reliable package... The torque will be a lot of fun on an autox course! Well done... Mike Quote Link to comment Share on other sites More sharing options...
johnc Posted April 26, 2012 Share Posted April 26, 2012 Just gear the car so you're at 80 mph at 6,000 rpm in 2nd and you'll be good. Quote Link to comment Share on other sites More sharing options...

Gollum Posted April 27, 2012 Share Posted April 27, 2012 Looks good, right about where I hope to be once I get MS and have it up and running. What are you running for fuel? Stock injectors + rail? If so, what fuel pressure you running? Quote Link to comment Share on other sites More sharing options...
letitsnow Posted April 27, 2012 Author Share Posted April 27, 2012 No, fuel system is siemens deka 750's + pallnet rail + AEM adjustable FPR + walbro 255. Running 38ish psi base pressure. Peak duty cycle was ~54%. LOL Quote Link to comment Share on other sites More sharing options...
Gollum Posted April 28, 2012 Share Posted April 28, 2012 Wow, got some fuel in reserve there? Planning for 500hp I take it? I'm still debating what I want to do for fuel. I'm gonna take the stock injectors to their limit first, but then it's either new injectors + rail, or adding a secondary pump and boosting the pressure as much as I can (I've seen 80+psi done on this forum, a loooong time ago). In the long run I want to run a twin injection setup petro/alcohol, in which case I'd probably HAVE to just run large injectors to simplify things.

letitsnow Posted April 28, 2012 Author Share Posted April 28, 2012 I got a steal on the injectors and it idles great, so why not? I am planning for around 400-450rwhp at some point, possibly on e85. Quote Link to comment Share on other sites More sharing options...
