I have a 98 trans am Bone stock this my second f body but the first LS1. Anyway I want a little more juice out of the car it's not fast enough for me lol an since I'm on a budget I can't afford H/C package and so on. So I looked at budget mods. If I were to install an Slp lid Pacestter LTs with a loudmouth exhaust and an ls6 intake since the 98's don't come with 1 approximately how much hp should I gain. I know it varies from car to car but just an estimate I'm at 305/?? Now wat should be my numbers after these mods and yes I'm still a rookie so forgive me experts lol btw I'm still fairly new to this forum so I don't know if this is the right section for this so if someone can point me in the right direction I would appericate it

Is your car a auto or manual?

Cj_ls1

Unfortunately is auto but I couldn't pass up the deal 7k with 39k miles on it in perfect condition

With some tuning on top of those mods you might gain like 30-40 hp

3200-3600 converter and tune should be your first mods.

Cj_ls1

Damn all that only for a 30 hp gain lol if I wanted to get the car to 375 hp without cam is there any other supportin mods without spray my goal at least right now is for 360 to 375 but I just don't see myself dropping 2k on a cam swap I would love to do it but I just can't afford that aleast right now thanx for the advice guys

Are you wanting 360-375 hp at the wheel or crank? Big difference lol

Cj_ls1

360 rwhp sorry for not being clear... Or better I hear its easy to get to 400 at the crank so how much at the crank is equaled to rwhp

Okay first of all the LS1 is underatted, and is more like 330-350 hp at the motor. Most dyno around 290-310 rwhp on your average Dynojet. With that said, and you being an auto with the mods you listed, you might be looking around 330 ish at the wheels (but remember dynos can vary) so that would be close to 400 hp at the motor

Cj_ls1

That's good to know, so will the mods listed put me somewhere in that area or do I have to have a cam for that?

The mods you mentioned are fine, but maybe to save a few bucks, hold off on the loudmouth catback and get a cutout. You'll be loud when you want, then quiet when using your stock catback.

Now a stall is a MUST for all autos. Its doesn't add HP that you want when on the dyno, but will help you take off faster. Usually good to knock off at least .3-.5 tenths of your 1/4

Good luck with your build and don't be afraid to ask us anything. We were all in the same boat and one time

Lid stall tune would be my first mods.

I put a lid, stall and tune on my son and brothers cars and they run 12.80s. With boltons you can run mid to low 12's depending on what converter you buy. Get a good 3600 converter (circle d or yank), also TUNED BY FROST does a good tune for 150. Look at spending around 1200.00. These are the best bang for the buck i put on my car.

Lid, cold air intake, and exhaust should be the first mods to any Ls car hands down...anything else wouldn't benefit if the base bolt ons aren't done first...

Cj_ls1

1200 is for parts and labor included right?

tnmotown

iTrader: (107)

Im assuming just parts. Lid is about $80, Stall $600-800ish if new, and tune $300-$500 depending where at.

You need to not worry about your hp so much. The race is about acceleration not hp.....unless you want a dyno queen. There are many ways to help the car accelerate.
