Re: Qtr mile time estimates

[big_red]

got a question for you guys ... it's about qtr mile racing

Went to heathcote a few weeks ago for a few runs down the qtr

I was running consistent 110 plus mph ... topping at 116 mph for the day but
could only manage a best time of 13.8 secs..

What am I doing wrong cos that mph should give a much better time?
Was running slicks as well... at 16 psi

I'm sure there are guys here that have run these mph before.... or more ..
Any tips would be greatly appreciated ...

[ALLMTR]

What car?

[big_red]

Hey AllMtr

It's a 88 CRX with a b18c - mild work, slicks, NA
weighs around 1050

any ideas?

[ALLMTR]

What turbo???

[big_red]

No turbo mate ... naturally aspirated.

just a mildly worked B18c

[phantom_civic]

what sus u running? (suspension)

[big_red]

tein ha .. had koni before .. don't really feel much of a diff for qtr mile

[ALLMTR]

So your running 116mph at the end of the quarter with a mild NA 1800?????

[GSI-PSI]

show mw ya time slip please. somethings wrong ere?

[EG5]

something is very2 wrong here . what is your 60ft time , what is your engine set up , on what car?

[GSI-PSI]

think hes talkin shit EG5. THis times pretty much impossible on a so called "slightly worked" motor. Fair enuf the B18c is in a CRX but still it cant happen.

[GSI-PSI]

and if it does happen, then where the hell did i go wrong wif my turbo teg hmmmm

[ALLMTR]

I think I've had enough............

[big_red]

I see there are alot of cynics here ...

don't have a scanner atm but will get the time slip scanned soon.
I'll type the details in ... this is what it says on the timeslips


Run 1
reaction time - 1.0761
60 ft - 2.2519
et 14.5539
mph - 112.36

Run 2
reaction time - 0.7669
60 ft - 2.6909
et - 15.2281
mph - 116.40

Run 3
reaction time - 0.6574
60 ft - 2.1728
et - 13.9405
mph - 114.16

Car's a gen2 crx with cams, pistons and ecu.

Sorry man but i didnt realise that ya car was turbo. In that case you need 2 learn how to drive cos i managed 2 get a 13.9 without slicks on a stock gsi with turbo on 7psi

[big_red]

Hey GSI-PSI


My car is NOT turbo mate .... never has and never will .. NA all the way :)

I've run a 13.6 before with less power ... so something else must be wrong ... hmmm

[pornstar]

Hey I can vouch for Big red, its not turbo and those were the Mph's he was getting.

Phil, its really in ur 60 foot dude, i think its ur suspension setting, sorry I couldnt get around to helping ya out, I didnt get much time running between friends, but with the MT's you could easily drop those 60fts down much lower.

You remember the 2 tegs? They were sitting on about 2secs flat with street tyres, so theres about 0.2 of ur time at the start, esaily worth 0.4 at the end.

[EG5]

Na all the way with nos?
something is very wrong with your time slip , it is super hard to do over 110 mph , my fastest mph is only 109.53.

[big_red]

Hey Eg5 .. definitely NA all the way .. no NOS...

If the mph was too high once then I agree but went over three times over 110 !

What are you launching off the line with your slicks? 6,000 rpms? 7,000?
I tried all sorts of launches but no good ...

any ideas?

[EG5]

8k rpm off the line with slicks.

[EuroAccord13]

If he's talking about the Heathcote Meet on 3rd July, I can vouch for his times, I saw his runs.....

[GSI-PSI]

ok im sorry ive made a mistake again lollll. Hey what exact engine mods have you done because i dont think its possible that its only "slightly" modified lol. Either which way Ya getting awesome times on a NA car.

[big_red]

EG5 - mate .. what type of clutch are you running? still holding up?
With 8k launches you must damn quick / good wth the gear changes! :)

Hey Pornstar .. didn't get much time to get to know you blokes on the day - maybe someother time. Yeah, the think launch is the problem as well.
Car may well be too low as well - gonna jack it up alittle ..
Maybe like what EG5 said .. I need to launch even higher??
Don't know if my clutch can take it! Clutch didn't feel right at the end of the runs anyway ...

EuroAccord13 - thanks mate. Like your car ... sweet ride
actually thinking of getting one as a daily driver :)

Hey GSI - PSI ...
yeah alittle disappointed I guess with the time .. will get down to heathecote again soon for more testing

mods are cams, springs, pistons, ecu ... needs more tuning

[panda[cRx]]

phil i dunno if you know but oshi's (from crxaus) b18c gen2 got 13.7 with the previous owner (spooky)

all he had was a microtech and very little engine work (i'd say what it was but can't remember)

[big_red]

hey Panda ... cool.. what mph was your mate running?

[panda[cRx]]

i'd have to ask him.
i'm getting a SiR b18c wacked in mine atm so i had a few ppl telling me about your time at heathcote :p

[EG5]

some 11sec trap speed there.

[big_red]

Panda CRX - cool. another 18c crx .. remember to upgrade your brakes as well! there's a few around eh. Where are you? Melb? I actually got a ITR halcut and transfered as much gear across as possible.
---------------------------------------------------------

Hey EG5 ... I wish ...:)
My aim is to break into the 12's ...
Prior to the latest work. I was doing a 13.6 on standard internals, intake and header & exhaust mods, slicks. Was getting a 1.9xx 60ft time then ...
Car's really put together for track not drags but Im curious as to what times I can run...
I can't get a clean launch .. either bog a little or bunny hop everywhere!!!!

you do have some nice top end there man! keep it up and you will see some nice time!:thumbsup:

[SINISTR]

Phil - is that you mate??? Phil from WA?

[big_red]

EG5 - thanks mate. Will keep trying till I get into your club! :)

Sinistr - HEy Mike... yeah it's phil here mate.
How's it going? Your car fixed yet? New kit?

[SINISTR]

EG5 - thanks mate. Will keep trying till I get into your club! :)

Sinistr - HEy Mike... yeah it's phil here mate.
How's it going? Your car fixed yet? New kit?

HAHA - thought that was you Bro!

What you need to do - is bring that BEAST back to perth... and better that 13.6 time here hehe ... get her into 12s - She wants to be driven here - where she was born... not in some 'melbourne' hahahaha!!! J/K

its going alright - and yes - the car is getting done - slowly!
I'll give you a call sometime :) PM me your number... :)

Mike!

[pornstar]

Phil, your mph is enough for 11's as someone mentioned before. Ur rpms are way too low for your launch, check your suspension settings.

With the street tyres on the tegs, they were able to launch at about 6,800 rpms, so you should be launching above that.

[big_red]

Sinstr - Hey Mike ... yeah .. kinda miss the motorplex with it's smooth surface and facilities ... tracks over here are a little rough
Give me a buzz when you can ...

Pornstar - how's it going ? Mate I wish for 11's !!!
Yeah .. thinking about it I was launching on average at around 5500 rpms and the highest I tried launching was 6500 rpms...

What clutches were the 2 tegs running? can withstand the constant abuse?

[pornstar]

Phil, with my 12.3 pass when i had the civic, I launched at 7,200 rpms, with MTs on you should be launching about 8k rpms, but surely ur suspensions need to be tuned man.

To give you a better idea, when I ran 12.3 on those street tyres, the Traps were about 119mph, and I still had more in it, just couldnt control all the wheel spin.

The clutches on their cars are custom made for me to a really simple design, that works. They handled the abuse fine :)

[crx_16x]

I can't get a clean launch .. either bog a little or bunny hop everywhere!!!!

Hey Phil,

How are your radius rod bushings?
Mine were screwed and used to result in a lot of wheel hop when launching.
Fulcrum have them for about $50. Or you could look into making up a new crossmember and radius rods with spherical bushings.

[big_red]

Hey CRX_16x ...

Not sure about the bushing ... never occured to me to change it actually...
I've seen some aftermarket cross members that sell in the US that supposed to help with traction ... but they're pretty expensive .. I think it's by a company called Z10 or something?

I'll lookup Fulcrum anyway .. thanks.

[crx_16x]

If you can weld, or know somebody who can, there is not much to them.
Here is a great thread on honda-tech http://www.honda-tech.com/zerothread?id=957387

You can buy rod ends at http://www.m-msport.com.au/MotorsportComponents.php?MenuItem=Suspension_NRE%2 0Rod%20Ends

EG5 does EGk20a run a full race crossmember?

[mugsee]

haha phil. stop lying and show everybody you're snail ;)

you mentioned that you're slicks were a bit too tall and you got a bit of scrubbing - could this have affected your 60"?

[online]

with decent suspension work, some bars on the back and 1.5x 60foot, that will be a mid 11sec car.. good work. :thumbsup:

[big_red]

mugsee - never !!!! I will never go over to the dark side .... Lol

Online - hmmm... stop giving me ideas !!! Lol
The missus is already on my case :)
BUT ... when you say suspension work... you mean ... get drag specific suspension? Any tips.. advice?
Running tein HA at the moment. Have not had a chance to get the settings right yet... not really sure what the optimal settings are.. guess will have to play around a little

Also .. is there a difference between running 13 vs 15 minch slicks?

Thanks

[pornstar]

phil ur tien HA wont be helping much, thats why ur 60foot times arent so good.

a better suspension alone woudl net u 0.35seconds at the 60ft. You can see the difference just suspension alone makes between the 2 integras.

[big_red]

Hey pornstar ...

What susy setup do your suggest? What setup were you using when you had your car??

[Mooro]

Big_red,
I'm really confused. Not doubting you just confused?
Can you give us the full spec of your car. From what I'm reading it sounds like you have a mildly modified B18C (type R) in an EF CRX weighing 1050kgs and it's capable of running low 12sec passes. It just doesn't add for me, even a mid 13sec pass doesn't add up. What's your secret?

[locote]

good quetion, how much HP does it put at wheels.
i was running low 13s in my 200sx with real s"_+t 60ft times, best mph was 113mph
i had sr20det fmic 3" zorst running max 12psi, putting out 280rwhp car weigh 1240kg

[big_red]

putting out 122kw at the wheels ...
