what can i boost ?

[ohio98eclipse]

i have a 98 gst with injen intake full 3' apexi exhaust blitz BOV, apexi avcr and a 14b turbo. I was just wonderin if i added a 190lph fuel pump what can i safely turn the boost up to? I plan on getting a afc this summer to how much would that help with my current mods? By next month ill have my upper Ic piping as well. Anyhow im just basicly wonderin if the afc would be worth it since im not gonna be runnin like 22 psi without injectors and i wont be getting those for quite some time.

16 psi max with the pump. Do some searching.

 

[ohio98eclipse]

i did and people said 16 psi without the pump...so what would i need to turn it up to 20psi

 

[1fast97gsx]

bigger injectors, safc, fmic ... not sure how long that lil turbo will last at 20+ psi levels.

hrmm how are people runnin 12's than on 14bs??? arent they runnin like 24 psi? how do i upgrade my14b to a small 16g? is there a rebuild kit for it?

i think you need to do some research on how the whole fuel delivery system works. in my opinion you need an afc, egt. and an adjustable fuel pressure regulator. the rest you have to learn how to do cuz there is to much to tell, i think you need to research your turbos more. cuz more boost doesn;t always mean more power especially when comparing different types of turbos. its all aout cfm man. bigger turbos produce same power with less boost. i wouldn't push it much above 15psi not cuz of fuel delivery but the benefits of the turbo boost start to go down because the intake charge is much hotter. not a great thing to do if this a your every day driver, wait till the afc is in, and then get the egt and play around on highways at 3am with boost levels to set it.

i didn't see the 98 gst my friends got one of these things. its way to fast he smoked a new cobra, zo6v and the camaro and the stang. i have friends who are all about muslce cars, and they are know acceleration. but when they got out of the eclipse they were like shit that thing is fast. you tap the gas and your already doing 100mph , i got his car up to 130mph in a blocks length and isn;t a very long block. here is what he did to it full 3" apex exhaust system turbo back and a o2 housing, injen intake pipe, aluminum flywheel (thats the key with the exhaust), some k&n filter, remove the boost solenoid restrictor, and a $400 hks blow off valve(a key thing for 2nd gens). and after doing this you will be smoking cobras, camaro's, and beat stock Z0'6. and you didn't even have to upgrade your fuel pump. ps he is hitting out 15-16psi on premium and has done it for years with no problems and its his daily driver

You are a ricer. A blow of valve is not a key thing, and a $50 first gen bov is good enough for 10s man. You don't have an aftermarket turbo listed ... I believe the fastest ever gone on a t25 is low 13s? Not fast enough to beat Z06 or cobras. Dream on.


As I stated before 16 psi is the highest I would go WITH an upgraded pump. After that you begin pushing the limits.

im hitting 16 psi now on the stock pump and it seems to be fine on 94 octane im gonna hardwire it just incase than ill buy a 190 walbro next month with my afc and injectors. thanks for the help guys

i am not talking drag racing i am talking cruising down the highway and going at it. of course the z06 will win in a drag. i didn't say to buy the greddy blow off i like the 1g blow off myself but my buddy has the greddy. i was saying what he had

 

[x camaro owner]

also on second gens replacing the blow off is impoortant with those as i pointed out but which one you use is up to you.

 

[1fast97gsx]

ok ... but a $400 HKS isn't necessary. ( you said HKS the first time ... now greddy ) BTW ... A dsm on a small turbo will have a BETTER chance against a Z06 from a stop ... on the highway the ZO6 will own a lightly modded dsm no questions asked.

 

[x camaro owner]

greddy hks no difference both are very good ment hks the second time. and i have seen this eclipse go. can you get wheel hop at 45mph cuz he can and some times he can get it at 60mph i have been in the car when it happens it scared the shit out of me cuz at 60mph you think the tranny is going to blow. don't how or why the car is so fast but thats whats done to it.

the funniest thing with the race against the new cobra, was that the guy followed him into the gas station and asked him what he had. all he said was a 4 cylinder. chevy v-8s don;t pull that great on the highway they ripp like hell off the line but top end speed power blows. trust me been there done that, blew that pos V8, the only v-8 that is i would consider fast on top end is my other friends barracuda and that cuz he has the wrong rear end and the wrong came. he has nothing but all balls out tope end power and no low end worth anything.

 

[PSiDAWD]

what kind of HKS BOV is it? $400? arent they around $200+?

are you sure its a z06 he raced?

 

[x camaro owner]

i am not sure what model hks it is big it a big honker probably a little bigger than a closed fist. you got me thinking if it was a real z06 now. new corvettes are like flies on shit on our town every time you go for a drive you will see atleast 10 of themif it is just a trip to the grocery. i am sure some one may have put the zo6 ground affects and decal on it is very possible, i have seen it done. just like at car shows with newer cmaro's and they slap that plastic corvette cover on their intake and people think its a corvette motor there is a big difference between a corvette motor and camaro its no where near being the same. hell the blocks don't even go through the same honing process, (this is why the corvette is factory filled with synthetic even for its break in period) any ways easy way to tell the difference in a camaro look at the head are the corners sharp edges, they corvette heads are rounder on the edges. i have worked on a enough corvettes and can do alignments on those in my sleep.

PS corvette owners when you get a 4 wheel alignment bring rear tie rods to, 8 times out of 10 they will need replacing. or jack the car up and check them in your garage at home, and replace them there. then get the alignment.

yea man no way that was a Z06 ... gsts on stock turbo ARE LUCKY to hit 13s. Last summer at Rt. 66 I ran a 12.8 @ only 104-105 mph. A Z06 on average was pulling 12.5 but their trap speeds were at @112 or so. They have A LOT more top end then we do, and I had an upgraded turbo ( 16 g ). Even the regular corvettes ... I ran against one of those. I ran a 13.1 and he ran a 13.7. Our trap speeds were VERY close though even though I was more than a 1/2 sec faster in the 1/4.

As for the BOV I'm only familiar with the HKS SSQV, which sells for $250ish. I was running that blow off valve before, then I switched to a greddy type S. There was no difference just a little sound. I prefer the HKS.

huh?

 

[x camaro owner]

jesus would stop with quarter mile times 0-60mph is a lot different than 60-120mph.

 

[x camaro owner]

have you driven many corvettes off the line they rock on the highway it didn't impress me at all

 

[1fast97gsx]

... whoever has the higher trap speed has more top end ... it's common sense. Especially when a dsm runs a faster 1/4 mile yet trap speeds are the same ... hmm which do you think has more top end given that?

 

[1fast97gsx]

Honestly no I haven't I own a 1980 ( slow ) and I have driven 1 ZO6 and that's it. However the ZO6 had crazy top end compared to my gsx.

 

[x camaro owner]

i have driven then both and a ferrari spyder (taught my friend to drive stick on it to grind grind wasn't my ferrari) and i have driven my friends eclipse and when i compare the corvette i would believe him, that he pulled away from the corvette.
