Tried it for fun..it said for my low boost and weight

11.27 @ 120mph

It was close to guessing my ET-but way off on my trap

 

I forgot to add driver weight.
You need to get that thing re dyno... I know that thing is making more power in low boost than when you got it.

 

The Cal says your running 510 hp with 3530lb car with you in it trapping a 11.1.

Your goign to be surprised when you dyno that thing.I does pull a bit harder up top than mine.

I think the best I will be able to run on low boost is 11.2, once I get a 1.7 on DR's. I hook up every gear, so I just need to get a 1.7 and move on. I will never be able to run slicks (BBK). We'll see this week.

 

using your ET and whp it says your wt. is 3390.6

 

If you use 11.3 and 480hp its right on the money. I know my car and my driving skill. 11.3- 11.2 on my low boost.

 

I was going off of Alberto's ET and whp of 11.1 and 490whp .....I should have said that

 

stock:

3300
250whp

13.7 @ 99

same e.t I got stock but I beat their trap by 2 mph though.

 

This one works pretty well, the mph seems to always fit. The ET will be really low though, as in a perfect run with an auto trans.



3500lbs @ 130mph=600RWHP


Does this fit your dyno numbers Alberto?

3500lbs @ 126mph=546.42RWHP

I belive 546 RWHP is what he has at high boost

 

Not even close, I trapped 126mph with 490whp on a Dyno Dynamics OR 525whp on a Dynojet in low boost-and I let off for a split second, and I can almost guarantee with me in the car its over 3500lbs.

 

are you using DD hp or DJ hp?

 

Tried for the fun of it, using Dyno Jet HP, it says I should be running about 12.30 at 110.6 mph. Looks like that trap speed agrees with me, but I have to work on the launch and get the times down.

 

I was using uncorrected DynoJet numbers. The mph seems to match my DynoJet numbers, but I guess most on this board use DD. It doesn't really matter, the MPH will show the power to weight ratio to a certain extent. I wonder when guys will be trapping in the 140's

 

I used Dynojet numbers, and according to Forcefed my car should have 600whp to run what I did bu **** only at 525whp...pretty fun to play with and does com eclose in ET, but off on weight and mph

 

what are you entering in for weight?

3845lbs @ 600rwhp=126mph

What would it take DD numbers to trap 132mph in a full weight car?

 

I entered 3550lbs and it was very close estimating my ET but was off on trap (my 1st post)

I ran 126mph letting off with 490whp DD (13psi), my highest boost level right now is only 15psi on 93 octane-that is 541whp on DD (580whp DJ) I think I can hit around 130mph + or - 1mph with that EASY but we will see.

 

i cant wait for the difference on the high boost runs!!!

 

600RWHP uncorrected my DynoJet will trap 132 in a full weight 350Z. What is the conversion that you guys are using to convert from DJ to DD? When you do the conversion are you using corrected DJ numbers in the formula?

 

No conversion I dyno'd on Sharif's DD STD correction then went immediately to a shop down the street with a DJ and dyno'd using a STD correction their. The numbers on my car were as follows:

13psi DD = 490whp, DJ = 525whp
15psi DD = 541whp, DJ - 580whp

Everybody has different differences between the two these were mine.

Jeremy-I dont think 50whp is gonna make a HUGE diff in trap, more of the diff will come from running at afaster track under good conditions...
