Expected mph gains?

[cp5899]

I just installed lt headers, off-road lead pipes, frpp sport cat back, jlt cai, ngauge with e85 tune on a manual pp car. What should be expected mph gain wise?

I see some people have gone 118 with tires and flex fuel with an auto. I ran 12.81 at 111-113 stock.

Yesterday I ran a best (limited by wheel hop) of 12.2 at 117. My best mph was 117.8 I think. Am I on par with gains? Seems others have gained more with less.

Just curious.


Thanks

What is it with people fixated on trap speed and not et?

Depending on conditions you should be in the 11s, not 12s. What's your 60'?

I'm definitely not fixated on mph, but seeing my 60 foots were any where from 2.0-2.5 due to wheel hop I couldn't get consistent et's. So that being said I'm trying to judge my progression by my mph.

I ordered all my bmr stuff so I'm hoping that helps out with the wheels hop.

I think 5mph gains from that combo is pretty good. Get that sixty foot down in the 1.6 range and it is a solid 11 second car.

Because MPH is a good measure of the actual power a car is putting down.

da makes a difference. 60ft times will help et not mph. a 1.90 60ft. will put you in the elevens. every tenth in 60ft. is 2 tenths in the quarter.

try shifting at different rpms to see if mph changes.

I tried different shift points and it didn't change much.

I'm hoping some of the new parts will help this coming week.
