Need advise on next mod

[dutman98]

I have a 98 auto. mods are mac longtubes prochamber mac dumps 4.10's plenum and throttle body msd coils and plug wires drag radials. best time is a 9.4 in the 1/8th on street tires. What should I do next? Keep in mind I'm poor. I was thinking pi cams and intake. I would like to do a stall but I dont think I can drop the tranny with the long tubes? I also have 112000 miles, so I'm going to do a compression test before I do anything.

anybody?

well...honestly...your auto..your gonna see amazing gains with a sct tuner..trust me..i have a 96 gt for referance with rougly the same mods as you...I went from 14.6-14.7 to 14.1-14.2 when I got a sct tune. The shifts will be faster, harder, and also your probably running lean with the long tubes. I didnt feel like the pi intake helped me that much when I got it... I think I run 9.1 in the 1/8th.

but pi cams and intake are a good mod

PI cams and intake.

i would say do the complete PI swap, heads and all. pick them up piece by piece and that way you can save a little money for the install as well, unless you wanna do it youself. or you could always work on suspension a little bit, getting control arms, springs, struts/shocks

with a 98gt 5spd, i got a fastest of 9.01 (average around 9.1-9.2)in the 1/8 mile on street tires with:

lower springs; 3.55 gears; k&n intake, t/b, plennum, k/c clutch; aluminum flywheel (i know, ur auto); u/d pullies; catted x pipe, magnaflow catback, tokico d-spec struts/shocks, and 2" lowering springs.

I might try a sct tuner but there is no dyno tuners around here. Would I still benefit from a tuner with out a dyno tune? I would like to do the pi intake and cams also. Im stuck between the two.

You will get more with intake and cam swap compared to a tune.

A 3800 stall torque converter and a tune will drop you almost a full second. The highest quality converters are BC Automotive, DirtyDog, Circle D is supposed to be good too. The PI's are good but not as good as the ones listed.

i'd get the pi intake and some mild custom cams instead of just the pi cams. of course with that comes the rockers and lifters and retainers and what not

well i just got the car dynoed today and i have swapped the pi intake on. Well i lost horses from the pi intake swap, the extra volume of the intake f's up the computer and makes my car at least run really rich after 4k. It was like 11.4 a/f ratio. it sucked. I would definitly go with a tuner from losota or something. They come with three tunes on them. Also, i was talking to dirty dog and he told me he could rebuild my converter and add a little stall like up to 3k for about 260 or something. Also one killer mod. Either go with dirty dog's converter or do the tuner. That will give you the best o and if you do the pi cam and intake swap ... go on and do the heads too, why not get all you can from the 10.5:1 cr ratio. Best of luck

Having just done a PI cam and intake swap I would recommend that as your next mod. Don't waste any money on anything else. Then your very next mod should be the SCT tune like justinschmidt1 said. That way you can get the most out of the tune.

 

[nesqwick_05]

i would say a tuner then cams and intake, so that you have the ability to tune the car incase things happen to you as they did void... and after you start getting into more mods you will notice that the tuner will be your best friend... :banana:

Well, with 4.10s, bassani ORX, transgo HD2 shift kit, and a tranny cooler.. i was running 9.2s on street tires.. not spinning except when i snapped second gear. Now i have a cai, hood that dropped about 50lbs, Predator tuner, and a custom tune imp: Cars good for high 8's now.. the torque modulation upshift crap really works.. your car pulls torque out when you shift.. so i bumped mine alot.. its crazy the difference the car feels bone stock motor to.. revised NPI intake, thats about it

 

[voidfinger]

so you made it not shift hard or somthing V ?

 

[Steven]

so you made it not shift hard or somthing V ?

no, i made it shift HARD and very fast.. i basically set the computer so that it throws everything the motor has when i shift it into second gear.. it'll snap your kneck.. its surprising for a week NPI motor lol Also bumped the timing and WOT fuel.. theres more left in the tune, but i havent had the chance to test some new changes ive been cooking up on paper. With the bump in timing, the cars horrible power band up top has really changed as well.. not that fall off in power like before the tune

 

[voidfinger]

yea my problem is that over 4k is to much fuel... it is suppose to stay around 12.8/13.0 but as soon as it hit 4k it nose dived and whent 11.2/11.1/11.0 :slap: I don't know but it is killing my power. The car stock ran a 175 on a mustang dyno and on this one after the o/r prochamber and catback, k&N, and the pi intake.... it only ganed 10 hp... Something isn't right and it is obviously the a/f ratio

So this coming up weekend i'm putting the npi intake back on and saying f it lol.

did you tune it though? I pulled fuel out after 4k.. and it helped

 

[voidfinger]

Naw, see i don't have a tuner right now. I'm going to get one before i do the pi swap anyway, since i want to turn the auto function off in my computer since i'm swapping to a 5 speed. :banana: plus i want to see what a tuned npi 5 speed will do b4 i give it a boost with the pi stuff.

How hard is it to tune with the programmer. You can actually mess with how much fuel is going in and all? How good are the tunes that come with the sct? I might try this mod first since it would be cheaper and my car needs a diffrent shift point from 1st to second.(It bounces of the rev limiter) If anybody could fill me in that would be sweet. Thanks all

Diablo or SCT.. SCT gives you more options, i just happened to get a deal on my diablo. I have options on timing and fuel.. for 2k-4k and 5k-7k.. you can adjust torque modulation upshift, shift points, shift pressure, and obdII functions.. its nice to have. Especially if the CEL pops on, i can just scan it clear it fix it.. if its in the tune that is. The factory HP tune isnt much in a diablo, stock timing and fuel.. i just modified mine to run with 87. There predator tune isn't bad, theres a definate difference when you install it and go for a ride. Just gotta understand and know your car well.. to be able to tune efficiently
