what kind of ET's are the 420a turbo's seeing?

[BigRand]

What kind of ET's are you 420a Turbo Guys seeing?
Those with forged internals and those without, and how much boost are u running.
Some of these GST/GSX guys are starting to get on my nervers, basically saying the 420a can't handle boost and becomes very un reliable. Anyone here having problems?
Horsepower numbers are nice too?

Well, ive only been boosted for like 30 miles and im having all kinds of issues! but all of my issues arent with my motor, theyre actually with my setup. I know that once people get the rebuild done, the issues drop big time! But, youre going to have issues if you but boost into a motor that wasnt made for it. BUT i will say this.... With only 5lbs of boost, i was able to beat a STOCK gst by about a half a car length .

So what kind of set-up issues, like fuel delivery etc? and how are u fixing them, Missing link, SAFC, megasquirt etc?>
Or what other problems.

 

[baxsom]

right now i just have hahns stage 2
slightly larger injectors
water injection
and built up engine

the last time i was on the dyno at 7 psi i put down 222 to the wheels
i ran 10psi at the track last time i went and my best time was 15 flat at 97mph
if i could ever learn to launch that speed should be good for at least mid 14's i think
because my 60' times were 2.5 seconds and higher

 

[SilverEclipseT]

I have been boosting 8 psi for about 18 months. I have had no problems. Car still runs great. Internals are stock and i have about 155,000 miles on her. I do change the oil quite often though. I havent been able to get it to the track though but my best guess is low 14's. My friends camero does low 13's and im right on his arse.

 

[Ajax]

I have no idea what my et's are yet since my clutch is not up to it. Dynoed 198 horses with 4psi since my profec E-01 froze during installation two months ago and still waiting for it. Build engine with lower comp. crane turbo cams. e-manage, and 550's for fuel

 

[siueclipse]

Best 1/8th mile time is 8.9, but I had a really shitty launch because I was getting used to slicks. Didn't have time to continue that night and that was the last night I was at the track last season.

I dynoed 337whp at 21lbs of boost UNTUNED (HRC supplied portfueler map). My motor has been built for almost two years without any real problems. I do a lot of maintenance on my car though. Changed out crank bearings, things like that.

Car runs like a champ.

nice numbers
what was your AF looking like through the whole run
i see the 11 up top but is that top end or average

 

[Burnett03]

Wasn't it siueclipse bragging about how fast and great his 420a motor was? I remember him telling me last year he could stomp my 1st gen awd, etc, etc. So any times in the 1/4 with it big boy? My friend had a fully built 420a with almost the same mods as you siuclipse (you have a bit more mods) and he only ran a 14.8. What a waste of time and money to run that

the 11.6 was constant when i was in boost.

I have no 1/4 times.

Basically put your friend can't drive.

i am still learning about the AF curve
so please correct me if i am wrong but that seems a little rich
not as bad at the 10:1 that i was at before i recaled my fmu
but isnt about 12:1 a good goal

how receptive is the hahn software on trying to tune that last little bit of air into it

yeah no kidding
siue has almost 100hp more than i do and i posted a 15 flat a few weeks ago

your friend needs to practice more

I agree he may not be able to drive but he has put down faster times than either you or siueclipse has posted. So until then he is technically faster than either of you two.

 

[baxsom]

DUH captain obvious


but if he has close to the same mods as suie
and suie has 337 to the wheels compared to my 250

then he should be way more than .02 seconds faster than me

I agree 100% and I said so. What would be interesting is to hear your ET speed vs his ET speed to see what you both are trapping at. Also some 60ft times would be nice as well. I've seen guys run 14 second times and trap at 120mph. Sad but true. For example with your trap speed of 97mph you should be running 14s. It's early in the season and I would expect you will too.

 

[baxsom]

i will be the first to admit i cant launch to save my life
stock clutch 70K miles
lots of slipping

my 60' was 2 seconds
1/4 time was 15.0
at 97 mph


but with the extra hp that you are talking about i could pull myself a better time even with a bad launch

a new clutch and i am sure that i could get my 60' better

You have to think of something though. With all that extra power needs to come more control. Lots of FWD guys don't get that and that ends up being thier undoing. When you make 350hp the wheels will break loose so much easier and you have to learn the proper give and take with the gas and the clutch. 2.0 is not a great 60ft but it is pretty decent for a FWD DSM. Most the guys I see need drag radials or slicks to pull better. What boost were you running and was that on pump or race gas?

seems to me that the car was wasted on your friend. a guy on 2gnt ran a 15.3 NA with just basic mods. its all about driving, and its obvious your friend is a 60 year old asian women


siueclipse has 1/8 times tho, and im sure they are faster then that doods 1/8.

2.0 60' isnt that great?? WTF seems pretty good for a fwd to me. look in the 1/4 time list. most of the 13 second awd guys are only pulling 1.8 or 1.9 and the fwd guys running those times are pulling 2.2 and 2.4 60' times.

I said it's not great, however I said it's pretty decent for a FWD. There are plenty of people who pull 1.9s on FWDs but in drag racing as a whole 2.0 sucks. AWDs and RWDs pull 1.7, 1.6 on street tires. Also who cares about 1/8th mile times they mean squat in the DSM world.

Besides who cares about siueclipse vs this guy anyway. That's not what this thread was about.

No need to get your panties in a bunch there. Just seems kind of lame for you to rip on a guys 1/4 mile times when you don't even have your own 1/4 mile times to put down.

i dont have any 1/4 mile times either, but a 14.8 with mods like siu's is just pathetic. 300whp and he runs a high 14? our cars are heavy, but come on. 2g GS-T's run 15 flats stock, and thats like 180whp

I agree the time is not great either but it's aways easier to critisize from the bleachers. Remember that at 180whp your not putting down a whole lot so keeping traction is not as big of an issue. There are tons of FWD guys on here who have said that when your making over 300hp it's easy to accidently light up the front tires even in 3rd gear. With greater power comes the need for greater control of the car. Make no mistake though I do agree that 14.8 is not a great time but I'm sure with practice he will get better.

o ya i know that too.. But i also believe our altitude had something to do with it also. Either way his times were horrible IMO and so was his driving
