dj haf we'll continue that thread here, so we don't change topics on that one guy....


Anyway, I'd say w/ the addition of the crank, new ignition system, and those other mods you listed I'd say it would drop you a couple tenths. Low 14s I'm sure. I had an AFPR in my L98, but I hear they don't do anything unless you change the tuning....or is that just in a more modern LT1? EIther way, I don't know what fuel pressure I was running, had no way to check it. I also know that when I replaced the OE distributor cap w/ an upgraded one, there was much better throttle response throughout the rev range. My Z had those mods listed in my sig, nothing major, but it had big ballz down low. Fish ***** up top. I hated the way it died out up top (after 4500 rpm). I think I'm left with the lasting impression of driving it around while I had the LT1 at the same time. The LT1 had about 265 rwhp when I bought it, and my L98 couldn't have been more than 180 rwhp by the time I sold it. But, I think as you said, my L98 needed the fuel injectors professionally cleaned, I think they were pretty bad off (original stock ones, 14 years old!), cause I noticed the performance was decreasing bad fast towards the end of the cars life with me....anyway,

Those mods will be sweet. What intake are you going to run? Super Ram?

Oh and for reference:

There you go guys.

 

i have nothing to reference the old post but based on the title im gonna take a shot. Here is the 3 step engine building process that you need to go through, we can help you with step 2 and 3.

Step 1: Figure out how fast you want to go

Step 2: Figure out how much its going to cost

Step 3: Scale step one back so it falls in line with the limitations around step two.

Seriously though what sort of times are you hoping to reach so we can give you a general idea of what youre going to need to get there.

 

I'm not lookin to build an L98, but dj haf for sure is.

My money is spent on the '95 LT1

 

ah i c, well then let my question be addressed to him.

 

If you noticed better perf with the new cap and rotor, your old one must have been shot.

AFPR is a cheating way of enriching your WOT. All it does is enrich everything else including the spot you need enriching. The best way is to set the pressure and then change the EPROM so that you have longer pulse width where you need it. Kinda of the difference betewen a shotgun and a rifle.

 

i want to hit 10's... 9's even, but as of right now, im broke

i am, however, certified as a computer engineer so finding a job wouldnt be a problem... i just need to fix up a few problems i have here at home before i can go out and find a $45,000 job... the moment i land a job though i'll be saving up my money for whatever i decide to do to the car. i wanna build it up all motor (427 ci or somewhere around there) with some nitrous to see what she'll pull, and then ill go forced induction when i want to seek more power. if i go forced induction, ill probably go with a ati s/c or a custom turbo made by probably south florida performance.... im aiming at the s/c though, it's too hot for a turbo in miami, in all honesty... ill have such a big over heating problem that i'll wanna throw the car in a lake if it keeps getting out of hand, lol

now... i was talking it over with my friend about what to do with the intake. he made a good point saying that i should leave the TPI setup so when i get the supercharger, i'd still have a crazy amount of torque down low while the supercharger builds up max boost at the end of the rpms. i like the way the lt1 intake acts on an l98 top end, but it'll kill my torque down low... the super ram wouldn't be such a bad idea because of all the torque it dishes out... but in all honesty, im not too familiar with all the intake setups that are available on the l98. i have to do more research, but the main objective would be low end torque and some hp up on top if possible.

the car's gonna be raced on the track most of the time, some street... seems that all the people i race around my streets tend to pu$$y out at high mph's for some reason... so i guess top end isnt really that big of a factor since no one wants to go up to 140, or even 120, with me, lol (120mph for now, i still have a damn speed limiter)

i'd still like to know what people think i'd be running right now... so imma quote myself from the post that orginally started this topic just incase people didn't click the link

 

oo, i forgot to mention, the moment i get an afpr, headers and gears, the next mod would be a new eprom... thanks aklim for your advice on when to get the eprom. i dont wanna get the eprom too soon and have to dish out money to have it reburned, lol, i'd rather just wait a little till i get more mods that i could actually benifit more from when i get the custom chip

 

okay think about what youre saying. To get into the low 10's high 9's youre going to be looking at making 1000+ hp trust me my friends dads vette runs consistent 9.7's and hes over 1000. When you have 1000 horsepower you dont worry about not having enough torque because your going to have more power then you could ever hope in hell of being able to effectively put to the ground. I think your only option would be the tpis mini-ram as it flows the most air of all the current efi intakes. You will need to ditch the tpi in a hurry because youll never hit the numbers you want with that restrictive hunk of crap. Ill say it again if your running in the low 10's not enough torque is not something youll ever think of, youll be lucky if you can keep the car from breaking loose every time it shifts.

 

getting to 10's is gonna be quite a while from now... but the moment i hit 11's, i'll be pretty happy. after i hit 11's, im going to be figuring out a way to get into the 10's, may it be nitrous, forced induction, or a jet engine on the roof of my car to get me into the 4's, lol j/k i just need to find some info on which intake setup would get me down the track quicker

 

mini-ram end of story theres nothing efi thats better. With the tpi system you will have a struggle and a half even getting into the 12's.

 

Yeh, I was going to say getting to the 10's even from 11's is a challenge in itself but more power to you.

Sounds like you have big plans for your car, whatever you do to it keep us updated.

 

for sure man... if i ever get the iroc dynoed, ill be SURE to make a topic about it... if i break 13's next time i run it at the track, ill let you guys know too. i made a website, iroc.djhaf.com but i havn't really dont anything to it yet because my computer died and ive been using a really crappy computer to go online and check out the board

 

Badass man. Maybe you could take pictures of your work and write about it. I plan on making a page about my spark plug install with pictures and instructions so I'll keep everyone updated.

 

A couple of things that come to mind;

1) After you hit the mid 11's the car will be almost Unstreetable, a real pain in the a$$ to drive at low speeds. Even with NOS or a blower.

2) The chassis modds will be Extensive, and Expensive to take the abuse.($$$)

3) Everthing you need to hit the 12's will have to be upgraded to hit the 11's, and again to hit the 10's. I mean Prom, Injectors, cam, convertor, headers etc...Remember...Combination.....(More $$$).

12's:
The 12's is a very reasonable goal with the TPI (IMO) however the 11's wil probably require shorter, fatter runners.
The MAIN thing is to get the power to the ground....TPI's are torque monsters! It's not easy...Chassis mods are a MUST. Things like the Lower Control Arm Relocating brackets like the ones from BMR that will help change the rear's Instant Center(IC)Raising the car, NOT squatting, pushing down on the tire and up on the rear body. A good cam+springs,1 5/8" headers, good cat-back, small stall (2500), minor head porting, base intake porting, either custom prom or bigger injectors or both, Drag radials, 3.73gears, shift kit,255Lph fuel pump...etc...and good tuning and driving...

11's;
I'd add either a Blower or N20, and resize injectors and Prom, More Cam, go to a 3500stall, 58mmT/B, Miniram or Stealth Ram intake, 1 3/4"headers, ET Streets,either extensive headwork or aftermarket heads and possibly 4.11 gears, possibly stroke it to 383ci.

Remember these are still 350ci engines...
The only way I'd shoot for 10's is a turbo or twin turbo set up, so it'd still be somewhat driveable on the street...my $.02
