My 997.1 Turbo 68mm VTG Build
Learning here, times will improve as I figure out the sweet spot. I have also raised the rev limiter to 7400 so I don’t have to make the dreaded 4-5 shift.
Stay tuned.
His 60-100 was "slow" on this run because he shifted 3-4th at around 95 and the time includes the shift. Otherwise this seems like a pretty stout run. 60-130 in 7.3x with a shift and on pump gas.....pretty great. I'll bet he is right and he'll be less than 7 with the right conditions.
I think I misspoke- it looks like he shifted at around 95, but I would assume it's a 4th to 5th shift (??) since he reached 130 on the graph. As Roffle says, best 60-100 times are in 3d and starting at 30 or 40.
With the 68s you should be able to get low 3s or even high 2s for a dedicated 3rd gear 60-100mph time. Start around 45-50mph and put a part-throttle load on the car and then floor it around 3300-3500rpm and it should
be good. I always did 4th gear 60-130mph pulls with my 68s and on Sunoco 94 (equivalent to ACN91, lol) I could get repeatable 6.9-7.0s times. Pretty decent for pumpgas.

no corn in Canada. 😢

There is a lot of corn in Canada, Ontario, Brampton. I have 5Drums if you need..LOL! Only way to fly with VGT turbos!
love following builds!
Yea. The only thing that we can really do here in Canada is to go with a meth kit. No e85 and race gas is too expensive. I am looking forward to a race gas map for sure. I promised myself I would stay away from meth, had nightmares with it in my BMW n54. That said I will probably cave when searching for more power.

Where are you getting your corn? Very interested if you could send me your supplier details.
You are right though, will be hitting peak boost by 3800rpm in 3rd.
Stock Injectors do not cut it with the beefier VTGs. You must get up sized Injectors to deliver the fuel requirements to maximize results.
exactly...your injector duty cycles will be above 90% if you use stock injectors and try to get the most from the turbos. Not a good idea! And that's with pumpgas
