I NEED TO REACH 9's!!!HELP!!

[eclipse98gs-t]

Hi ima Peruvian Dsm owner, im runing 10.42 et's with an fp3082 forged with Ross pistons eagle rods, i have a magnus intake, hks 272 cams, my cyl head is also ported polished, my block is blueprinted and balanced, im at stock displacement, reving 9500 rpms, i just sold the fp3082 to my friend who owns a skyline, i NEED to hit 9's no nitrous, im also geting c16 imported from the states, i was looking at the gt4094r and the new fp gt35hta, should i get the gt42r? i need to hit 9's, i need good opinons please, no flames

Hey man check out this thread. I beleive he is running the gt4088 and made 700hp and 696tq. He has also already ran a high 9. http://www.dsmtuners.com/forums/showthread.php?p=151309906#post151309906

if the sole purpose of the car is purely to run 9's or faster, go with the gt42r, if you want a more streetable car that is capable of running 9's, go with the gt35r or the gt35r hta, it will be a challange without nitrous, but is definately possible. You have to think, "what is my final goal for the car, when will I be happy with the car?" only the answer to that question will tell you what turbo to go with. If you want 1000 whp and a 7 second timeslip, GOOD LUCK, and get a gt42r, if your looking for the most streetable 9 second car you can have, go with a gt35r hta, if you want a good balance of the two (being able to run mid to low 9's, possibly, POSSIBLY 8's if you get your car very very light, while still being somewhat streetable for a mid 9 second car) go with the gt4094r. All of those turbos CAN run 9's, its just a matter of how easy you want it on yourself and what the car will be used for. Obviously a larger turbo will spool slower, be less useable on the street, and run faster times at the track with the proper supporting mods. In the end its your choice, no one can make it for you, so you simply need to look at what you want out of the car.

Its a full race car no interiors fuel cell huge anoying aeromotive fuel pump fiberglass hood and other stuff, i want easy 9's, but with the gt42 r and standard displacement wont i loose time with all the lag it produces

It works for Shep with standard displacement, a full interior and a 42r. I believe he hit low 8's without nitrous.

 

[lenny 15]

Have you checked out any of the holset turbos? The HX40 might work for you. The reason most people didn't reply is because 99% of us haven't run 9's.

 

[Boosted98gsx]

That, and trying to run 9's in a FWD is freakin difficult.

Car is 1990 talon tsi awd, sorry about my nick but cant change it.

What injectors and engine management are you running? Since you don't want to run nitrous I would recommend that you go with a bigger turbo and use some sort or anti lag feature. I see that you said your running an aeromotive pump? Is it the A1000? Getting these cars into the 9's is influenced a great deal by driver skill and tune. What RPM are you launching your car @ currently and what tire and suspension set up are you using? What's your elevation and track prep like? Also the more information you can give us about your set up the better.

 

[Slippi84]

Are you against nitrous or just trying to see what you can do without it before you spray cause with a built motor like yours it seems like your a perfect candidate for like a extra 100shot on top of your turbo to put you into the 9's and not even have to change your setup or tune as long as you go with a well designed wet kit like zex.

edit: To your worry about lag on a 2.0 motor and a gt42r it's a track car and reving to 9500rpms you should just lauch higher and you would never notice the diffrence spool wise as you should already know from your experience transient response with a duall bb turbo like the gt42r is much better and being that high in the rpm band you will never drop out of the sweet spot. And with no interior a loud ass pump and what not I doubt your really worried about streetable.

What kind of fuel are you currently using?

Profile says walbro 255 in tank with aremotive 1000 external and 1000cc injectors

 

[fwdeclipse]

I think he was asking what kind of fuel as in pump race gas. In the first post he said he gets c16.

 

[Boosted98gsx]

Yea, if you want 9's, I'd drop a bosch 044 in the tank, then bulk head another externally, Y them together with -8 or -10 out then that to the rail. Fuel is going to be a limit for you as well, not just the turbo.

An Aeromotive 1000 is 1.5's as big as a walbro 255. So he's basically got 2.5 255l/hr pumps. Should be covered in the fuel delivery department.

 

[Boosted98gsx]

If the aeromotive is in line with the walbro, then he is only flowing as much as the smallest port in the fuel system will allow. Basically, the Aeromotive becomes a "booster" pump to make keep the walbro flowing at maximum at higher pressures.

Until you get the pumps in parallel, you will not achieve maximum flow.

 

[TurboAnything]

Thats not tru because AMS runs all booster pump setups in there 35r-42r kits.

 

[dnhieu]

i think if you hit low 10s you shouldnt have to ask how to hit 9's. its obviously big turbo, lots of tuning, and learning how to drive/launch time...

 

[twicks69]

wow, a big pile of nothing for help so far.

As FWDECLIPSE stated in the first response with the link to my car, it is easily possible with a 4088R, 4094R, 4294R or 4202R. The 35R is pushing it, but entirely possible.

As for fuel, you have enough to get into the 9's, but if you want to go any faster, you will NEED 1600cc injectors, or use a second fuel rail with 550+cc injectors on top of your 1000cc fuel rail. Twin walboro fuel pumps are enough for mid nines and 700+whp (1 in-tank, and 1 in-line) with -6AN feed, and stock return line from firewall-back.

Run a 0.95 A/R or larger T4 divided flange turbine housing on a 4088R, or a 1.01 A/R divided flange on a 4094R or 4294R and get mid 9's easily.

FYI -- I am nearly at full weight and am a STREET car. There should be no problem for a RACE car to hit 9's on this turbo -- especially a 1G.

He has enough fuel and if he didn't he would have figured that out while tuning and checking a/f ratio's in the 5k and up rpm area with his current setup and we have already stated larger turbo and the option of the gt35r POSSIBLY doing it with a near perfect tune. I don't see how you helped out any more than anyone else

I think I see yoru problem if yoru only suspension mod is tein springs you need to invest in a full coilover setup big time man. A good tuned suspension can be as vital if not more vital to a fast straight trip down the track then actually making the power.

Twick did say he had enough fuel to break the 9's. He then says if you want to go faster he will need more fuel delivery.

I see that but the OP isn't asking how to I go faster then 9's he said I NEED TO REACH 9's!!!HELP!! If he has enough fuel to reach that then how is throwing fuel upgrades out there helping ???

He was just throwing some useful info out there, with 1000cc's he must be close to the limit expecially if hes planning on 9's or better. If hes going to run a gt42r he might as well get the most he can. I was just trying to say his post didnt hurt anything.

Just because what he posted was repeated by other people gives you no right to flame. From what I see, he is the only one here with a 9 second car that is giving advice from personal experience. Now, where are your useful posts? All I see from you is bashing on other people and it looks like you dont have the dsm that it takes to speak from experience.
Also, it doesnt appear that you have any awd experience either so you really dont know if just a set of Tein springs would be adequate for 9 second 1/4mile passes, do you?

 

[twicks69]

The most effective way to make your powerplant get 9's is listed above. On a 2.0L with a 4088R or 4094R your 272 cams will be just fine. On a GT2494 or 4202R you might want to look at a set of Brian Crower 280 cams or equivilant.

Again, anything larger than a 4088R will require larger than 1150cc injectors. I am maxing out my 1000cc injectors at more than 90% duty cycle by 6000rpms, and over 115% by 8000rpms on 49psi on my 4088R. That is why I reccomended a set of 1600cc injectors -- this will easily do over 850whp and can do 1000whp. I would also reccomend using adjustable cam gears and tuning the car on a dyno to extract the best power for your powerband using whichever turbo you go with.

Next, Find a decent T4 tubular exhaust manifold. I am using a DN Performance ( http://dnperformance.com/catalog/product_info.php?cPath=22_28&products_id=70 ) manifold with good luck for more than 2 seasons now. I would try to run better reinforcing bracketry if you go with a 40R or 42R as they will likely break off. My manifold has not cracked, but the reinforcement brackets are broken off. The key issue is the weight of the turbo that is hanging off of it. You will be able to fit a 40R or 42R on it with little modification. I am running a 12" SPAL slimline fan on the passenger side inside the engine bay for cooling, while using a stock radiator and am able to clear a 40R with no problems. To run this setup, you will need a TiAL 44mm Wastegate and will need to make a tubular dump pipe for the wastegate.

Use 2.5" intercooler piping if using a 40R, and use 3" intercooler piping with a 42R.


As for traction, your current suspension will get you into the 9's no problem -- it has been done before. You will need to drive the heck out of it, but you can do it! I would still reccomend upgrading to a coilover for having more adjustability. I would also reccomend getting a good alignment and make sure everything is straight as possible. K-Sport Kontrol Pro coilovers are a cheap and effective way to get alot of tuning for a low price. Otherwise, you can go with alot of other good options. Having a solid driveline and suspension is key when launching your car. Be sure to inspect all your suspension bushings and upgrade them. You should already have motor mounts and transmission mounts to get this far. Also, tires are pretty darn important, but I do not know what type of track preparation they do down there. Is it just an abandoned airport runway, or is it a real race-prepared track using a traction enhancing compound? If you can get better tires, then do it.

Finally, tuning is extremely important, along with putting the power to the ground (traction). Invest alot of time in getting the car dialed in, then get used to driving that amount of power on the street/track to get a good handle on where to be shifting to keep peak powerband and best traction.

Good luck!
