i just got an update from the shop.

[lucky7]

i was going to do the internal gate GT3071r, on the stock manifold. that all changed.

anyhow, i got deatschwerks 650cc's, GT3076R .82 a/r, SSAC manifold, tial 38mm wg, etc. just got a text message. car made 453 @ 15psi. injectors are maxed out. shiit, i thought i went big enough. haha. im gonna talk to one of the guys later tonight. so ill get more info then. im happy, but at the same time dissapointed i am being held back by injectors. i know they planned to crank it to 18psi. i guessed 450 though . granted it was on a dynapack.

anyhow, ill get some more info, some pictures, and see if i can get a dyno sheet.

anyhow, this is the most recent picture i have of it. haha.

i just want to drive this SOB.

[mott6904]

453...THAT S**TS WEAK....just joking

Get some vids of that beast

[240z4u]

Killer number on a dynapak man! Get us some curves!!

Congratulations, time for bigger injectors. Not sure why they were maxed out (I suspect its because those dynos do read lower than a dynojet from what I hear).

i suspect it has something to do with me cheaping out and buying deatschwerks. haha. being that they are just re-drilled squirters, maybe i got a bad set. i dont know. that'll be more than enough power for a while. assuming i can get a ride, ill pick the car up tomorrow. then get some decent pics.

[Shocker]

Your injectors shouldn't be maxed out, are you sure your fuel pump isn't at its max? Maybe even your FPR? Was anyone watching the fuel pressure during the run? It might have been falling off...

[Coolwhip]

i was thinking the same thing.

Anyways, good stuff on the results, get in that thing and ride, let us know how it feels

[kouki-gymkhana]

You should not be maxing out those injectors at that power level. Something is a bit fishy with the fuel system if you are running out of fuel at ~450 whp with 650's. I would spend a couple of days at the shop going over the fuel system with a fine tooth comb to triple check that everything's A-OK before you pick it and start beating on it. I'm tired of seeing threads about people blowing up their newly built motors (Shocker, lol, just kidding)

[cdorhout]

I agree with the guys above, shouldn't be maxing 650s. My current setup is GT3076R with 550cc injectors at 25psi. I'm not even maxing my injectors yet. I don't have dyno numbers either though.

[gawdzilla]

what fuel pump?

[lucky7]

walbro 255lph.

i agree. i figured i was good for over 500 with 650's. thats why i didnt get the 740's.

just called up there. something isnt how it shoujld be. hahaha. they're gonna call me back in a few. i

Walbro's maxed unless you hardwire it or use a boost-a pump. Which will help a little bit. I suggest getting a bigger pump, or another to aid it.

[rb25drag]

This is why i say **** injectors and fuel pumps and Map sensors and MAFS, ETC!! They suck bananas!!!

Propane is the only way to go Cheap and efficient.

[lucky7]

i didnt hear for sure yet. but i think you're all going to LOL, if it is what i think it is. hahahaha.

[mott6904]

Well dont tease us what do you think the problem is. I need a good laugh today

[matafied]

hmmm your running a factory fuel filter and its restricting ur flow??? hahah c mon man whats the problem?

[BoostFab]

get 1000cc injectors and never look back

[lucky7]

talking with alex, the guy that put my pile together. he thought i installed the 650's. im 95% sure the 650's were in a box on the passenger seat when i talked to him today. looks like i somehow made that 453hp, on stock injectors. LOL! like i said, im not completely sure. but it sounds like there was a mix up with the work order. hahaha.

anyhow, alex drove the car today. he said he hopes i have a spare pair of undies. cause the shiit rips. he was on this forum a couple years ago. slow_240sx or slow_240. he had a red S13 with an RB25. he since, sold it and built a green S13 with an LS1. heads/cam/tune. it makes 420whp. he also has a full tub and a ford 9". badass car.

[BoostFab]

yeah i remember him on here while back. that green s13 is hot.

[jdmae86]

I have a friend that made 419whp with stock injectors... with his ****ty tune the injectors were maxed to the limit.

[lucky7]

i was stuck at 420 for half the day. then they somehow squeezed 450 out of them. that HAS to be it. ill call 'em in a few hours when they open. haha.

[mott6904]

is that with stock internals? If so i cant wait to get my 20 tuned if it keep it

[lucky7]

yeah, its all stock.

[lucky7]

car is done. i was right, there was a mix up. its on the stock injectors still. lol. somehow, it got mixed up, and my FPR and 650's are still in the box. i talked to the boss up there. he tuned it so i could beat the **** out of it on the street. said its VERY reliable, and the spool is amazing. it never goes above 90% duty cycle. high boost is 453 @ 15psi. low boost is 12psi. its finished and waiting for me to pick 'er up. i guess ill hold onto the injectors and FPR for a rainy day. sucks sitting on $800 worth of parts. but if its reliable as is, i guess ill be happy. this should be MORE than enough power for me. for a very long time. i just went from 300, to 450 in a few short weeks. its going to be interesting. i STILL have 225's on the back. gonna install my CF hood when i get it home, give 'er a bath, and go hunting vipers. .......from a roll ofcourse.

[ninety1two40]

i was going to do the internal gate GT3071r, on the stock manifold. that all changed.

I am thinking about running the internal gated GT3071 with stock manifold. What made you change your mind? I'm looking to get around 400-450whp.

[lucky7]

what changed that?? the first 2 turbos they ordered, were off the shelf units. they sent 2 with T25 flanges. a T3 flange they said would have to be custom + a couple hundred more dollars. so for a couple hundred MORE dollars, i could do a manifold and WG setup. with a slightly bigger turbo. so i said eff it, and went for it.

i hear that off the shelf, its hard to find a turbo that size, internally gated with a T3 flange. not very common upgrade on cars.

You should go hunt down some tires first LOL. 40mph roll on 225s is going to give you wheelspin city. While it looks super impressive, its annoying as hell!

Congratulations again man.

Evan

[WhatsADSM]

You REALLY should get those 650s in.

But that also raises the question. They are telling you that you made 453whp with 90% IDCs on 370cc injectors?

[lucky7]

yup, i was thinking the same thing. ill ask them for a dyno chart. im sure they wont have one though. as long as its reliable, its not all about the power. my goal was 400 and reliable. if this is it, im happy.

thanks guys.

[gawdzilla]

numbers seem a bit inflated for the setup, but like you said, who really cares as long as it drives great and does what you want it to do.

[lucky7]

i drives better than ever. i drove home with the wastegate turned off. its plenty fun like that (7-8 psi). haha. they gave me a few dyno graphs, and its a straight line up to 7500rpms/453hp. who knows how its calibrated, but so far so good. like i said, it drives better than ever. no funky idle, no hiccups, no fuel cut. the wastegate dump is louder than i had anticipated. i must confess, it scaerd the shiit out of me the first time. haha. anyhow, going to give it a quick wash, and go hit up woodward with alex. we should go tagteam some Fbodies. rofl.
