What kind of trap MPH should a 700 hp C5Z have?

RonSSNova

I’d say near 140 depending on how well you can get the power down.

Crank or wheel?

I've never had a fantastic 60ft, but my car is around 750hp (638rwhp) and I trap 132mph like clockwork.

I agree with RonSSNova if you're talking wheel horsepower.

Car makes 700 wheel, RXT and 26x10.5 MT ET. Hasn't been down the track yet but I was thinking it should be in the 142 area

Yep... you're correct.

My car makes ~660rwhp SAE and has run 138-139.

Seems low to me for that kind of power. I Plan on being around 130 with heads/cam/intake making under 500.

Keep in mind a few things:

You need a tire to get any type of accurate reading.
Weight and track conditions will play a significant role.
MPH is significantly influenced by driver despite what people think.
PUC will have a much greater impact than peak hp on et and mph on a drag strip.
Clutch type can/will influence mph.

Many other factors play a role too and they all add up to make the difference.

That's why one car with 700whp may trap 130mph and another may trap 150mph.

nailed it!

I made 685 to the tire...... left on the foot brake at near 0 boost..

Great slip! ^^^^

I can only dream of getting that kind of hook out of mine. Awesome pass!

junk c5

Thx, When I can leave on boost and turn the ramp rate up, that bitch is gonna go 70’s all day.

WA 2 FST

Easily.

Running a stick, I can't leave on boost (haven't been serious enough about it to run a 2-step), so that hurts me a bit.

FLT level VI 4L65E . I’ve got a PTC converter that I can foot brake to 3800 and I had my tuner mess with the tune on the 2 step. I can build a few lbs on a cold tire on the street. I haven’t tried at the track with a sticky tire. I’d be content foot braking 5lbs of boost for me to leave with. I didn’t make it to the track this year with my most recent tune

RonSSNova

Better/bigger rear brakes will help on the foot brake.

junk c5

I added a set of strange single caliper drag brakes. It did help a little but not like I was hoping. There’s not much for brakes for a 16” wheel. I haven’t been to the track yet to see the exact results. Just a little alley testing. I left the factory booster on. I do have the strange manual master but haven’t put it on

RonSSNova

Discs are tough.
They just don’t have the holding power of good old drum brakes.

junk c5

True. I’ve got a Ford 9” under my mustang, 1986, with old school 9” “Big Brakes” that stops at 164mph at 3200 lbs.
