Topic: Help me to reduce my drag racing times

[kennysabarese]

1) No CAI has shown improvements in power.

2) Graywolf showed that head porting didn't do much.

3) Someone really needs to show us results with water/meth. If your IAT2 is low, the question is how much lower will it get with water meth. I would talk to Lyndon about this.

4) NOS sounds like cheapest and easiest way to make power for drag races. Not sure what graywolf means by being hard on pistons... power is power what difference does the method of power increase make?

I think you need to find if anyone has made huge power on the LNF, like bates, or GM racing. It seems to me that the big power ecotecs are not LNF

As for weight, I would remove simple stuff at the track. Stereo should pop out in 3 minutes, passenger seat, 5 minutes, air compressor, 10 seconds.  Can't hurt and doesn't take much time. But you are right, for drag racing, power is probably more important than weight reduction because the weight balance may not be as important and you won't get a gain from handling.

A good experiment on weight would be to take a 200lb passenger with you and see how much your times change.

1) I agree pretty much but look at shabby 
2) I agree, stock turbo is bigger bottleneck than the head in our case
3) Besides good IAT2 I think I use slightly better gas too so the predicted gains looks minimal, I asked Lyndon some time ago and he did replied only something like "you can try".
4) I think graywolf meant that is a big step in power and might lead to engine failure, I don't know anybody else except ZZP pushing LNF, there might be some others too (ie. BTF tuned sol greasejockey, GreenRL with his GT35 BTF kit, but they don't share too many things so I can't be sure about their power levels)

N2O, water/meth, slicks and removing parts from the car will bring me into race category, I think I have enough trophies in street category, I should drop street and go for race, I didn't do it until now because I don't have a winner trophy to complete my shelf.

I can't test with passenger because I'm not allowed to race with passenger.

get meth do it you know its calling you

Ah ok... so upgrade the pistons

I can't test with passenger because I'm not allowed to race with passenger.

Oh that stinks. Maybe try on street with Dynolicious to get some indication.

1) I agree pretty much but look at shabby 

Yeah I wonder how much could be attributed to each part. I felt that the upgraded IC has the most to do it cuz it lets him go more advanced on the timing cuz the temps are lower, but you and shabby are more similar with bolt ons, you have the IC and exhaust and MAF #'s are even lower than me!

How about, relocate the MAF, then completely remove the intake pipe, then there's no restriction! See what MAF reading you get that way.

[Kelu]

slowsol:  I think you want me to do it so I can prove with data ? I know Balt guys are meth preachers but ...
Going meth now and N2O later leaves me a question, instead of paying 250-400$ for a strong meth controller and another hungreds for N2O I'm thinking to buy a standalone which would manage all things (N2O, meth, 2nd step launch control, wot shift) because the prices of standalone's price dropped a lot these days. I can buy a Haltech controller for 900$ which will take care of those and avoid to plug all those things separately.

Kenny: the difference between me vs you and shabby is GMPP. I might try it initially with stock MAF. I was waiting Kuprito (he did that and Opel has a different OS than US kappas) but he doesn't provide me with any real data yet.

[2.0 tspeed]

i know meth works :-) my vw brotheren run it along with of course my cobalt buds besides its good for our engines :-D whats not good about being on 100oct all the time i would run e85 if we had larger injectors for our cars.
btw bottles are for babies

[2.0 tspeed]

oh kelu i took out my friend srt4 last night he got back from the army and he was like so wanna run i said ok, he made 270whp i pulled him pretty easy sorry no vid he didnt want to show himself loosing.

Yeah but you and I are pretty close, I thought Lyndon's tunes for 2.7 and 3.0 sensors were close to the same and just our elevation was the main reason I make more MAF than you.

[Kelu]

Slowsol: w/m for octane raiser??? The w/m mix is only about MAX 15% of the combustion (calculate based on w/m nozzles), 50% 116 meth means about 7% 116 octane mixed with 93% 93 octane gas results a maximum 1-2 points in octane. 100 octane because of w/m is another myth brought by people who don't have data to prove it.

Kenny: Elevation modifies MAF??? Where did you spent your holiday? 

[kennysabarese]

Higher pressure at sea level or something right? I do have vacation amnesia.

[2.0 tspeed]

Well kelu from my experience with Vw and all our software to run watermeth we have to switch our software to 100 oct mode while running watermeth, email apr or revo they might b able to give you data to back up there claims I'll get more info give me a few today

[Kelu]

Revo representatives from my country are my friends, they do see a lot of gains because of w/m because they have weak intercoolers.
But their performances are awesome:
Audi S3 stock turbo stripped (our engines are 95% same): 12.4s, with water/meth 12.2s, upgraded to GT3071 and more stripping 11.4s
VW Golf 5 GTI DSG with k04 with slicks 12.4s
All times in the same track as me.
In this moment I'm regretting I bought a kappa and didn't went VAG, I put over 5 grand in performance parts and I have   I didn't went VAG because they don't have RWD cars but my performances are a reason of jokes of my friends  

[LatinVenom]

But you just said slicks, and that my friend makes a lot of difference on drag racing.
I have not done it in a lot of years but the right equipment will improve your time, provided you are a good drag racer.
The last thing,  I certainly would have never bought our Kappa if my main intention was to go drag racing.
You can see that even with V8's the Kappa car does not run that well in the 1/4 mile.
One last thing, I would certainly give Vince at Trifecta a change to tune your car for drag racing and see what kind of ET on the 1/4 you get from his tune

[NormSky]

Was the S3 a DSG also? Your not going to beat non-manual transmission turbo cars unless your making gobbs more power.

An automatic transmissioned Redline is almost .5 faster just to 60 mph. If it had DSG it would be under 5 second to 60 mph.

[Kelu]

Audi S3 is manual, their times were done with street tires (Michelin PS2), their only advantage is 4x4, but they are heavier than kappa because of that.

VW Golf 5 GTI is the only one using slicks, that is a damn 200hp stock engine non DI, his advantage is DSG (one of the greatest automatic gearboxes in the market), the engine is stock, turbo was upgraded to k04 turbo and some supportive mods (injectors, fuel pump) and he did a damn 1 second faster.

Let's stop looking to other cars cause will not help us.

I bought kappa with the plan to bring it to 400 hp, I thought is a great platform for that power and keep it streetable too, in the beginning it looked easy and not too expensive. 400hp would brought me to low 12s at least, I'm not aiming 10s with this car.

[NormSky]

My point is you will not be consistently the fastest or near the fastest. Miss a NLS and you'll have slow race. You can't out drive today's electronics as you already know that. You'll spend anothe coupld of grand just to match VAG. Join the club or find another sport like something with turning and braking.

[Gentleman Jack]

Kelu,

correct me if I'm wrong, but the DSG is actually a manual gear box (dual clutch set up) that is then electronically controled to make it act like an automatic?  That is the tranny that started the "BLURRY" line between auto and manual transmissions.  Now we have auto's that we can shift and manuals that we don't have to...

Either way, you are right.  Focusing on the fact that all your friends are faster than you is not going to make you any faster, it will just make you angry.

Keep working on it and you will find a way.

[Arabas]

Kelu, here are some suggestions:
1. get rid of your old friends, find some new ones 
2. open engine, upgrade turbo, upgrade fuel pump, loose some weight off the car (start from ac and passenger seat and maybe some fiberglass parts instead of steel)...but this means lots of bucks...
3. find or make a 6 speed tranny that would work better for 1/4 of a mile (that's where our main difference with VAG cars is)
4. keep the beautifull kappa for casual racing, drifitng, girl-finding, travelling, autoX etc and buy an old Opel (Ascona, Manta) or Ford (Capri, MkII) or even a used EVO VI or VII and with 5-6K you can make it reaaaaaaaaal fast for drag racing.

i wish you would go with solution #3, but i believe the best thing is to go with solution 4. keep your car and buy an old one to make it a drag car.

Arabas: 

[Arabas]

which solution made you freak out Kelu?
from #2 to #4 i was serious

[Kelu]

I freak out because you suggest a completely different approach with a dedicated drag car which I decided to drop some time ago.

[Arabas]

i understand, but maybe you should do some research and think about it again.
this way u will have two toys to play with

[Kelu]

Nah, case is closed about a different drag car.

[kennysabarese]

upgrade fuel pump

Which pump? HPFP or LPFP?

[Arabas]

on most cars, the most common to change is the HPFP (especially VAG cars with 2.0L turbo, take the RS4 HPFP). on our car, according to a guy on another forum, the one that needs replacement is the LPFP. IIRC, DDM did the mod for him
