should I hope for 12s-first at the track in a DSM

[90AWDTalonTSi]

My car is almost road/track ready, and I really dont want to get to the track and hope for something I'm not going to see. I've never raced a DSM (at least not being the driver), so I'll have to learn the car. It should be easier to launch than my GTP, right???
what ammount of boost should I shoot for?

Here's my mods:
16g
255 FP
exhaust header
MBC
cut airbox w/ K&N
studded head
BR metal head gasket
4-angle vale job
Balance shafts removed
2100 lbs ACT pressure plate
6 puck clutch


Mods on the way:
Evo O2 sensor housing
2.5 inch exhaust
Cyclone intake
20 over forged/coated pistons
Tires-undecided-maybe Nitto's or Comp T/As (if I can find any)


I'm hoping to have the 255 installed before racing. And I still have to clean the intake and SMIC.

Thanks

PS-I've only had this car for 3 weeks, and just dont want my parade rained on

Your parts are capable of a 12 second pass, but are they setup properly and can you drive? If it's your first time out aim for high 13's to start and see where it goes. You may not get the pass your looking for espically if your aiming for a low et like a 12.XX and you have never been out before.

I'll tell you one thing, your fastest pass isn't going to happen on your first visit to the strip (or your 5th even..)

If your running the stock SMIC i would be careful of heat soak, let it cool down between runs

 

[Eclipse96Ryder]

ya u could maybe do it on 18lbs and some race gas...let us know

I'm guessing a 13-14.5. Reason being I don't know if you've had it tuned very well, and you dont know about all the stupid extra crap you have to deal with being in a DSM (such as the SMIC cooling down as someone mentioned earlier). Someone on the board took theirs to a track with more or less your mods and only hit a 14.6 or something, with a fair launch (1.9 60' or around there), but then in the last 1/8 mile his car crapped out due to heat soak (we think as of now). Read up on the track talk section here and see how everyone else launches, and you'll do better

After racing a S/Ced GTP for 3 years, I think some of it should come natural.

I think my 60ft will rock-I only race at NRP (Norwalk Raceway Park-Norwalk OH). I was honestly hoping for better than 1.9 60s, the GTP cut 1.9s all day long on street tires and is FWD.

If the does have 12s in it, I know I can race it to that the first night. I'm good at racing a manual (real good), just need more practice driving one-.

Could I just take a water sprayer and cool the SMIC down faster? Is air plane fuel OK to use on these things? its 100LL

Only 18lbs of boost-I was hoping 20


The only problem that I foresee right now is :
I'm broke and need tires for it
I need to adjust the clutch-it takes to long to shift

With that setup, expect a mid 13 second pass. If you can drive and tune, then you may suprise yourself and run a faster time. I dont see any injectors or tuning tools (like an SAFC) on that mod list. If you want to crank the boost up, you really need to have those things. With just a fuel pump, I would keep it around 16-17psi on premium, maybe shoot for 18-20 with race gas.

 

[JessesTalon]

I say 14.3 if ur lucky...





With DSM's you never know...


when I first got my car on stock slipping badly clutch... i had a 3" exhaust non mandrel bends and a baffled 3" muffler... (300$) mbc 10$ on ebay 15psi and I ran a 13.5


but then look at my mod list... never got better then a 13.6 even with all the mods I have now(look at profile), and I am a pretty decent driver I would say.


you just NEVER know...

 

[90AWDTalonTSi]

Whayt size injectors would be good? My ultimate goal is 10s, but 11s by next year.

Whats and SAFC, and how much are they?

 

[JessesTalon]

depending on turbo... if you want 10's and 11's I'd say get 720 or 860 for now... if u need bigger... there are some pretty good injectors that flow like 1000cc+

S-AFC is a tuning device many people with DSM's use it allows you to change your lean/rich conditions under certain rpm points...

lean = Less fuel more air
rich = more fuel less air

run to lean... blow your motor...
run to rich... fuel cut...


tune it right and you will be loving the drive even 2 min down the road to krispy kreme! tuning is a big fast ugly biiiatch.... have fun with 11's and 10's

Before you ask anymore sever newbie questions like what is a SAFC, go here and READ as much as you can: www.vfaq.com

Also, I would expect a mid 14 second pass. You aren't hitting anything less than that with your stock 1.8" full exhaust. You need to ditch that asap and also get a downpipe.

My honest suggestion would be not to race that yet until you complete some vital steps. Upgrading the turbo without fuel mods or even an exhaust isn't smart....

 

[herostar]

if you're going for 11's, and especially 10's, I'd suggest getting 3" exhaust rather than 2.5". Also, get that exhaust on before you go to the track... it'll help your times significantly. IT would be allright if you went now, then put the exhaust on and told us how much it helped...

Also, for tuning i'd recommend dsmlink www.dsmlink.com
Just as a note, aviation and automotive fuels are rated differently. Your pump gas is actually derived from the equation (R+M)/2 = AKI (to you, octane). R=ASTM Research Method (RON) for deriving octane, M=ASTM Motor Method for (MON) deriving octane. Significance of the MON is that it is the octane number for aviation fuels. A rule of thumb (reference: http://www.eaa.org/education/fuel/detonation.html) states that MON is approximately 5 points less than the AKI (what you're interested in).
also read: http://www.prime-mover.org/Engines/GArticles/octane.html
These two sources seem contradictory to me...so my advice is to just run 93 since you shouldn't run a massive level of boost anyways due to your stock 450 injectors and lack of fuel management.

 

[90AWDTalonTSi]

The info is strange to me on the aviation because I ran that in the GTP and it alway felt stronger and had less KR. I always ran 94 octane if I didnt get to the airport soon enough-.

OK-I understand what a SAFC is-it like my ICCU for the GTP (except I could control timing also). This is kinda hard knowing the inside and outs of a car-then swithing to something TOTALLY different. names, places, things are all called something different. Just gonna take some time getting used to this.

Thanks for the input on the exhaust-for now I'm going to run 2.5 (the price is right-FREE). Then sometime next year I'll go with the 3inch-gotta pay for that one.

I dont understand the point of all these stupid vacuum lines , and freakin interference engines-I lost my first head (just valves really) a few days ago and had to put the backup head on it. Sucks whn you gotta put your backup stuff on it and havent been to the track yet. Done venting now.

Now I need to learn

I'll prolly be at NRP this Wednesday (I hope, I hope, I hope). The 255 pump is in , its a loud little thing .
Does anybody in NW Ohio have one of these SAFC that I could watch them use it, so I new what I was doing? When I get a job, I'll have to get one.

here is a link on which vaccuum lines you can remove... it might be a link for a 2g, but you can find them for a 1g on this site too...
