thats awesome , can not wait to test mine

 

Solid well done build, been enjoying the read and learned a few things. Thanks for sharing!

 

Did I miss the dyno charts/results and 60-130?

 

It hasn't really been on the dyno turned up, although it did make 1111 on a dynojet. I thought I posted a graph somewhere in here.

All of the tuning/data has been at Texas Invitational roll races, which start from 60mph so I don't really have any 60-130 data yet. Planning on taking it to the half mile November 11th so I will have more info then.

 

To do a 60-130, you need to start at more like 50. Just hitting the throttle around 60 doesn't give you a good 60-130.

 

+1
And I would say Rix's 100-150 will be improved as well when dedicated run.

My guess regarding his built/power is low 4' at the both runs 60-130 and 100-150.

 

Not sure but it may not be at full spool or acceleration until past 60 though to get a good 60-130 number. Looking forward to seeing it though but I think 100-150 is a much better indicator in bigger turbo builds like this one.

 

Since I'm accelerating to 60-65mph, then holding for 3-5 seconds and then going it gives fairly useless numbers for 60-130. I could've done 100-150 with one shift instead of two for a faster time as well. Thought it was worth sharing still.

 

Looks like a fun event i love these formats ,so it's basically a rolling 1/2 mile ,we've got 2 events over the next 2 weekends here in SoCal, next week is Shift sector which is a standing half mile ,unless you wanna roll some one, you roll to the cone & go but thats less than a 1/2 mile as the roll zone is part of the 1/2 mile .Then the week after next weekend is No Fly Zone event which is appears to be the same as your guys event with rolling half mile ,with the roll zone not included in the 1/2 mile.You get higher traps in the rolling 1/2 mile seems to be about 5 to 7 mph faster for me ,i just got a new turbo set up so interested to see where i'm at now ,previously i was 169 mph standing 1/2 & 176 rolling half ,i got some new GT2 68mm modified vtg turbos installed this week.

 

Are the new ones also Champion 68s? I'm interested in hearing what you think about them as I have the regular Champion 68s.

 

I was told 780hp on the dyno but dialed down to 750 to keep it safe & not hitting to hard ,stock rods.Bbi guys know there stuff & start conservative ,probably still some dailing in at the event with some data logging ,these guys show up & support there cars at these events.

No Gt2 cores sent out to Tial for htz 68 mm ,not sure of all the details the BBI guys did the specs for them,also the latest ERP clutch revision as apparently the old one wouldn't shift with the Hp # & an LSD guard diff while i was in there.

I'll post a new thread after the events.

 

Congrats on your great build really enjoyed the progress of building your dream machine..This is a great thread for info and have seen your steps that I can learn from.. question on torque delivery do you have pump gas dyno were we can see your spool rate and throttle response.. even if limits are kept @950 would be nice to see how fast you get up there.. keep up the good work..

Turbos hit around 4k but the torque limiting sacrifices some power. It hits peak torque around 5,000rpm and does it really smoothly. It's great for traction, but the car would be quicker if I could just let it go.

Here's the 93 octane dyno graph. Because I have the M&W Ignition they didn't have the right tach adapter to get RPM on the dyno, but you can do a little math (T =(hp * rpm)/5252) to figure out torque at any given point in the graph.





pump gas dyno pull

 

Very nice and consistent 93 octane dyno graph!

to what rpm you limited this pull?

 

7200-7300 I think.
