last year I ran a 14.3 on a 65shot with a stock intake, exhaust and budget y-pipe

mods since than 1 step colder plugs, new air filter and a 85 shot

I went to the track and was not able to beat my old time, the car was making more power at lower rpms and would spin 1st and spin 2nd when it shifted alittle but in the upper rpms the car would just bottle-neck and I could feel it hitting a wall

I am going to put my cai on I think I just found the limits on the stock setup or do you think the stock pump can not keep up with a 85shot

 

Do you have a Ypipe?, exhaust can choke ur setup. free flowing exhaust helps ALOT with nitrous. I strongly suggest you get urself a 190 walbro, stock one above 75shot i dont think is too safe. Dont push ur car like that again, if it feels like ur slowing down at top end like that, you dont kno if your leaning out for some reason. Get a pump. setup ur exhaust properly, maybe a cutout or something. Dont spray from the line!! unless u have slicks.

what was your 60'. give more info on your times. 60', speed, 1/4, etc...

 

dang dood, care about your car?

 

yes I do have a y-pipe

best 60ft with a 65shot 2.0

best 60ft with a 85shot 2.1 (spinning)

best run 14.3 at 92mph with both the 65 and 85shot

I have my rpm switch set at 2000-6500rpm

running the stock tires 205/65/15's at 17psi

do you have the part # for the 190 walbor, I was thinking about the 255 but think it will be overkill for what I am doing

 

get a walbro 255 hp

 

Maybe some tuning will help out. EU is a little hefty on the wallet, but given that and WB02 then maybe you can squeeze out a good 5-15 HP (obviously you can't get the full 15 while spraying because you can't advance timing).

I don't think you should run an 85 shot on stock pump either.

 

You are spraying too early, Try spraying from 3k or maybe even 3.5k.

 

I pump felt fine, it feeling like the intake and maybe just was not flowing enough for the shot but I could be wrong

I putting the 75shot back in and installing my cai, also I will be pulling the plugs to see how they look, if I was running lean it will show

but I do plan on getting a new fuel pump just not sure if I should get the 190 or 255 I plan to run a 100shot in the future

 

if you are going to go with a 100 shot then I would recommend the walbro 255 high pressure. I'm running a nos system 125 shot with the walbro 255

 

well I pulled the plugs and the looked fine no signs on dentation, put the cai on made a pass on a 75shot it feels better pulls harder in the upper rpm range. well guess the real test will be when I go back to the track

 

Betcha you need more rubber on the road - maybe try some cheap slicks ??

I do need more rubber and when I burn up my tires I will look into the slicks but it will not solve my problem with the car bottle necking I think between the cai and stepping down to a 75shot this will help, next I'll starting looking into a fuel pump

 

Do you have a nitrous pressure guage? As the pressure drops, so does the HP output.

Also heating the bottle is really important, if you don't have one, get one. You can also do what I did, I simply put the bottle in a tub of hot water, kept in there a good hour, and then wrapped it in my surfing wet suit. It worked, kept the temp up the whole night.

 

I already have a guage and bottle warmer or you can just eread my sig

DYNO TUNE?

I think I found the problem my bottle psi was about 100psi lower than last time

 

Your 1/4 MPH is 93 with a 75 shot?

 

no with a 65

 

hmmm. with 75shot I got 98mph. You should be up there with that 85shot. Something might be wrong. What was your bottle pressure?

 

the bottle psi was low around 850-900 but when I ran my 14.3 I only trap at like 93mph

question is gss342hp the correct part # for a walbro 255 for a 4gen auto and it is correct that I can still use the stock fpr with this pump

need more speed

 

Dose the 255 walbro pump bolt right in or do I have to mod anything? I have a 5th gen 5spd W/80 shot.

 

Running the 1/4 with anything less then a freshly filled bottle is pointless. And you will only get 3 or 4 chances at running your best time. After that its all down hill on the nitrous. 92 MPH seems pretty low. You are getting good 60' which is giving you good ET. But the mph is lacking I think. You are auto though right? Auto + low bottle probably explains it.
As you spray (even a bottle will full pressure) it loses that pressure. And if your spraying for like 10+ seconds as you probably are going down the 1/4 track, the bottle can't keep the pressure high enough so you will start to bottle neck at the end. You spray 1st, 2nd, then when the car starts to hit the top of 3rd (or 4th if your stick) your like wtf? feels like the nitrous is empty now or something? It sucks too because if you have a wet kit the fuel solonoid is dumping fuel in but the nitrous solonoid is lacking nitrous. So you are running super rich. I am so damn close to 13's its not even funny. Once the track opens by me I will hit it though! Got a 01 AE vlsd tranny going in my car right now. mahaha

 

Excuse me ?? Automatic + hot bottle seems to work for me.... I was in the high 13s with a single 75-shot, before I got serious.

 

Dont get cranky on him Harol lol, he just meant that the low bottle might have been the reason why he didnt trap higher. lol

 

I plan to good back to the track next week and will put the bottle in a bucket of hot water before I go to the track then put it in the car with the bottle warmer on for the ride. I am hoping with the bottle @ 1000psi and the cai the bottle-necking will be gone and I'll get a 13's slip

 

Yeah, I figured, but picking on automatics = sadly misinformed by anklebiters. Time to lay that myth to rest.


Heat up that bottle, spray at 1100 psi and 43 psi fuel, through lines big enough for the flow, and if that doesn't work, up the jets !!

 

with bottle pressure at 800psi, thats not good. I think i ran a 14.6 when i had bottle pressure that low(no warmer). then i went back with a warmer and ran 14.2@98mph with same 75shot.

yep, funny how poeple dislike the auto but you should see the reactions I get when i give people a ride on my car, stays at full boost the entire run without the needle even moving and shifts are quick. and i quote "damn that feels like when I drove a DSG equipped auto, shifts are soo fast!" lol. THEN they like the auto.

 

Automatic = Consistancy

I always thought that people that dragged with autos are cheating :P

 

Why yes, we are....... Until we engage the TC clutch, then people KNOW we are... Heh.

 

You should really drive my car some day.... slamming the automatic's gears and smoking the slicks, it's all good.

 

grey thought you would like this I started putting a nitrous kit on my 91 s10 with a chevy 350 today, since there is nothing else to test out with the maxima right now due to the snow and I will not go back to the track till next week

 

That's what I'm talking 'bout! Real 'merican big iron, with spray! Are you using a carb plate, and is it "wet" ???

When I was "coming up" with V8s, it was all carburetors, cams, and headers. Slicks were expensive and rare in the 60s and 70s.... and nitrous was only in dentists' offices...

It's probably a good thing I don't have any extra garage space, or there would be a cast-iron BBC in there.

 

yeah it is a wet carb plate nitrous kit, chevy 350, edlebroke intake, 650 holley, headman headers, full msd, 2.5 inch dual exhaust & d/r's 275/50/15's the only bad thing is I am still running the stock heads and cam with 8:5-1 c/r but with a 100shot and some traction I am hoping for high 12's

I and hoping to hit 13's with the max this year and 12's with the truck .. then this winter I'll dig into the motor with a new cam, heads and bump the c/r to 9:5-1, with a 150shot hopefully this combo will be good for low 12's high 11's

my biggest problem is making time for both cars

 

It's a tough job, but somebody's gotta race two cars at once.....

 

Yo, tom here is what I think you should do:first if you go above a 75 shot you should convert to a wet shot, If not then definitely buy the 255 fuel pump, next I would get a b-pipe because in the upper rpm's you'll really need it and it will definitely raise you mph.

This is just my 2 Cents. I wanna see you get there man.

If you go tomorrow night (friday) give me a call. I'll take a ride over with my stock se-r to get some baseline numbers before my modding and spraying starts.

 

I plan to run a 100shot in the future so wet or dry I am going with a walbro 255 and afpr maybe nismo not sure on that yet and get a 2.5 inch b-pipe, muffler and fuel psi gauge not sure on the order just yet

And as for the track I am not going too cold tomorrow, but it should be warmer next week and I'll be there then

 

Cool,like I said give me a call if you go.

 

hey question does your budget b-pipe bolt directly up to the stock muffler or did you have to mod it alittle

 

Bolts right up

 

thanks, all opinions are welcome. do not give up on the max I want to see you their also.

I think the b-pipe will be the next mod on the list plus if I let my buddy at the muffler shop install it he may throw in a magna flow cat for like 20 bucks

hey bring the mevi with you next friday so I can check it out, I found a machine shop in the area encase I can not fix it myself

pm me with a price I am going to AC this weekend
