On 10psi heres what it ran:

With better launch i knew i could have reached the 13.99 mark.

every run i improved in the following times:

Impressive.
When you say stock, how much clutch and dowel pins are you using?
And how much of the car is "race" compared to "street" ? weight, creature comforts, bumpers

You turbo guys are lucky, every time I race my NA-DD times drops the later it gets

Stage 1 KEP clutch with dual friction disc. stock 4 dowel pin crankshaft. I weighed it that day and its 1900lbs even with me in it. I weigh 180lbs. so 1720lb car. bumpers has just t bars in front and decklid removed for racing.

its a full interior car minus back seat and has 58 sqft of hushmat sound/thermal deadener. electrical is all stock and working condition, stock suspension, stock gas tank, has both the front seats installed, full glass inlcuding the windshield wiper. its a nice restored cruiser that i finished this year

That is very impressive, to do all that and have a complete car

I've done 13.9 with 3 different ways with my stock 1600 (+turbo + efi)
with 1.1bar of boost and 150km/h topspeed - all worked great
with 1.6bar without first gear 160km/h
with 2 bar of boost but with broken pistons and no power at all with 4 th gear 150 km/h
