How much boost is it running????

That's a lot of hp from 2.4 liters....

What size turbo? How much boost? Is lag an issue on the track?
Thanks

The turbo is a Precision with a ~60'ish compressor wheel and a ~65'ish turbine.
boost is pretty stable on 1.2 bar(wastegate spring pressure) up to 6500 and from there it creeps up to 1.75 bar @ 7500 where i stopped on the dyno last time.
before i have had it up in 7650 on the dyno with climbing HP numbers and on the track 8200 RPM without any signs of the engine loosing power...
also with backpressure 0.7bar under boost pressure i have more horses waiting :)
I'ts not laggy, but my grandpa style gearchanges may give an impression of that but the few times i changes gear fast it's fast on boost again.

since i have spent 3 years collecting parts and saving money and building it , i will have some time on the track with these numbers to get some quality time with it :D in the end of the season my goal is to exceed 2.0bar and go 8000+ RPM AND start using the boost control to get boost form lower RPM's
I left the boost creep as it is , since it gives the engine the extra punch on the top end . it's like a porsche GT3 on crystalmeth!

a funny story during testing , i actually blew the wall out of the combined plenum and IC's... yes i had been a coward with the amp's on the welder and not calculated the forces on the weld. it actually is almost 1000kg force on the wall at 1.5 bar boost.!! :shock:
so i had to crank up the amp's and made a lot of reinforcements inside the plenum :)

it does not seem to influence airflow :)
