115kw DC2 running low 15's

Kinda brings my back to my original question though. A 115kw dyno tuned DC2 with my mods, is expected to run high 14's? I didn't think this was the case?

every dyno is different... Some dyno's you might get 98kw some 130kw...
cant really base it on much..

what was your kw pre and post tune?

[Moya]

Didn't say mate.

It's all good though, I'm gonna hit Willowbank another couple times (for experience), then have it retuned by DynoDave and see how she goes. Then I'll hit it again and see how she goes after Dave works his magic.

Cheers

Dynodave tuned my vti-r, it also made 115kw... it ran a 14.3@96mph


This was with over 250k km on the original, unopened motor too... Very similar setup to yours. Let dave work his magic, you will not be disappointed...

Also keep in mind your DC2 'VTi-R' 1176kg is heavier then a DC2R 1117kg

That is nearly 60kg heavier (one asian passenger LOL)

Also with your 60ft(your launch) being 2.346, if you managed to get that down to a 2.0 you'll be quicker by roughly 0.692 sec with the exact same setup.

So 60ft 2.0 = 14.5 approximately

How much petrol did you have in the tank at the time?

A few tricks you could try before you head out next is:
-Remove Spare wheel+tyre jack+tools
-Have 1/4 tank of fuel
-Lower your front tyre pressure to 25psi and rear tyres to 35-40psi
-Do a nice burnout

PRACTICE PRACTICE PRACTICE! and Good luck

So many mods and only 91mph..
Im sure ull feel a great difference once Dave tunes it...
That same MPH that my GSI teg was running except i got a 15.1..
untuned B18B with Cheapo 4-2-1 and custom zorst, stock honda ecu..
Ur car should SPANK it!!!!!
GET IT RETUNED ASAP BRO

lol pne asian passenger! lol im asian but im 74 kilos! all muscle

i have a vtir iminal mods! only had a VAFC att he time, stock sussy, had a cannon muffler, ran a 14.996 at abotu 90 mph! 72 mph sounds too low

[DLO01]

Your times/speeds are fine.

Just need a better start ie 60ft.

Its your 1st run. You'll get better with practice.

[fatboyz39]

no way a dc2 will do 2.0. 2.1 or 2.2 yes.

For dc2 with those bolt-on easy 14.5's.

No way 2.1???? hahaha...

[xtercii]

I wasn't going to post this but i figured i may as well give you a similar comparison. I've got a 1988 CRX (would weigh aprox 920-950kg at the track) which i have put a JDM B16A1 in it. Its got a 2inch exhaust and a microtech computer, which we road tuned. vtec set at around 5,000 i think and rev limiter set at about 8,500rpm (which i used most of at the drags hehe). After 5 runs i got

reaction: 1.057
60ft: 2.265
330ft: 6.221
660ft: 9.567
M.P.H: 73.77
K.P.H: 118.72
1000ft 12.420
E.T: 14.851
M.P.H: 92.23
K.P.H 148.43
Over/Under 14.851

I would assume that your car would have more power than my car with the mods you have done. The weight of my car compared to your car would be a huge advantage though.
Next time you go to the track, muck around with tyre warming (If you are using street tyres you will probably find that a huge burnout probably won't make a huge difference, but i would do a little one at least to get some of the sticky rubber off the track onto your tyres.
Then muck around with launch revs, probably go around the 4-5 depending on how sticky your tyres are, if they are hard tyres drop down to 3-4,ooo rpm.
Then try droping some pound in your tyres, try dropping the front tyres down to around the 20-22 pound mark.

I am not an expert at drag by any means, I've only done it 3 times just to see what my car would do. This is just some thinks that i have tried which made made the difference between a low 15 and a high 14 for me. and also some knowledge that i have gathered from 5 years of hillclimbing and circuit racing. Give it a go and see what happens. As everyone else has said, practise definatly makes perfect.

Maybe I did come off the throttle to early.

Here's the full dump of the data until I take a pic of the timeslip. Maybe it'll shed some more light on the issue?

OOOH. I think I've quoted the wrong MPH!! There's two. The bottle MPH is 91.59 which sounds alot closer to what you guys are thinking!

Which brings us back to the original question!

Thanks guys!
