Ok so...a few months back I sold my mustang out of being bored. I picked up a 1988 base l98 with some work done. That being said here is what was done.

350 original Block bored and dipped to 355
Freshly rebuit.....
zz9 cam
zz4 Alm heads
24lb injectors
TPIS long tube runners
TPIS cer coated headers(eliminated two front cats)
Magnaflow cat
Magnaflow cat back exhaust
160 thermostat
52mm throttle body
2400 stall
Dana 36 rear w/ 3.73
TPIS Proformance chip
TPIS intake

So I took the car to the dyno. How disappointed I was. The car has 300rwhp and 400+tq. It Tops out at 3300rpm's. I need to move the power band. I would be happy with around 400rwhp. Not that i'm a racer but I brought the car to experience the 1/4 mile. One of the thing in life I always wanted to do. I'm not a mechanic and dont proclaim to be. So all work done will be subbed out.

My goal is to be able to respectfully finish the 1/4 mile. My objective is to gain 75-100 rwhp. In simple terms I have a corvette in need of Viagra! Something to wake it up!

Thoughts I've been given
1 mini ram or stealth ram
2 Replace cam and injectors
3 100 shot nitro
4 Piggy back a tune to the chip

I really dont think shooting spray into a topped out motor is such a good idea. I might be wrong ....but doesn't sound like a good idea.

I also dont think replacing the Cam and injectors is gonna solve my TPI intake problem.

Again all thoughts are greatly appreciated. I did alot of reading and reserch on this and .....It depends on who you speak with. It can be confusing at times. But because I'm only trying to increase my hp to 75-100 I needed to build a picture of whats going on.

 

Different cam heads and intake for sure, sell yours to offset cost. 100rwhp is quite a bit.
Also need larger injectors and a real good tune plenty of guys here to help you with that.

 

300 rwhp isn't bad for zz4/113 heads.

Since you've already got too much gear for an LTR set-up, you could use a taller tire.

Check out the new Hoosier 28x10x17 drag slick, or 325/45R17 M&H Drag Radials.

Could be a low-mid twelve second car as-is with some traction.

 

ZZ4 heads aren't really any different that stock 89-91 alum heads. They flow less than 200cfm. Aftermarket heads (or TPIS porting) would get you another 50cfm per cylinder. (AFR's are at least 80cfm above that). You're not going to get 100 more hp w/o different heads (or serious porting).

A miniram is your best starting point for immediate gains (and in terms of price). I skipped mentioning the SR since you've got steep gears. It just might run out of breath before you're happy though. Again, it's the stock heads.

The tire idea is a good one too -- at least for the track. And, as you mentioned, how good is the tune?

FWIW, you're ~70hp above stock (with nearly an equal gain in TQ).

BTW: I bet the car is fun to drive. The intake is the main stumbling block for a track car. Heads don't help either. But, for a street car, obsessing over dyno numbers isn't going to do you any good. How's it run in the 1/8th mile?

 

Ty for all reply's. The Dyno tech said the tune was perfect. It seems to me that the guy i brought the car from ran out of money to finish the project. From what he has done it seems like the next step for him was a TPIS mini ram. Don't get me wrong the car is in perfect running condition. A few friends have said just drive the car and be happy. Its extremly quick off the line the tq is just unreal. There is no dought in my mind that the guy built this car for light to light. I guess the real question is will this car be competitive in 1/4 mile. Keep in mind I have never done this before and I dont mind coming up short because of driving. I dont want to fail because of equipment. Is it worth the money? I can't answer that question....not yet anyway. Is there a budget? I have no budget but dont want overkill. There is no reason to spend $4000 if $1500 will get me where I want to be. Remember the goal is to competitive in 1/4 mile. There is always going to be faster cars then mine....I'm not a gear head..(no offense). I'm lacking hp on the end of the 1/4 mile. My local track over here is Englishtown NJ. I think I'll go check it out this weekend.

 

You state you want to be "Competitive in the 1/4 mile". The real question is... What is Competitive mean to you ??.. you have not stated your goals completly other than wanting 100 more ponies.. But as it has been talked about.. the top end of the engine has a lot to do with top end power. The L98 intake has always been a the weak area when trying to make more HP and RPM's.

Are you looking to be competitive with the guys that run every week ?.. (less than 10.5's) or just the street guys..?.. (11.00 - 13.00 range) ?

Also keep in mind....the faster you go.. the more things will break..!.. the IRS will most likely be throwing U-Joints or the Rear Gears if itself in that Dana 36, a 44 might last a bit longer. Trans and Staff are another point to look at.

Being Competitive also has a lot to do with driving, how well the car has been setup for the 1/4 mile launch.

 

What kind of ET's has it run ?? ...................

 

Increasing power will definitely reveal weak points in an ascending order.

 

I'd like to be in the low 11's. I'm just trying to find out as much information as possible. I'm looking to start whatever I decide to do by January. I like the thought of the mini ram. However if you really read through the forums its hit or miss. There are alot with casting issues. TPIS is way overpriced but seems like the logical place to start because of the TPI faults. Who knows that Mini Ram might put me where I want to be!

 

Not w/o GREAT heads too. Even then, you're looking at upper 11's.

 

I agree. I bet it's tons of fun -- the kind of fun you can experience EVERY day vs the occasional run at the track. I agree with your friends.

Which is why you should be happy with what you've got. There's several ways to getting a faster car. I'm betting you'll need a better intake, better heads, and NOS to get to the low 11's. You're probably looking at $4-5k (for the cheapest route).

I don't call low 11' competitive in the 1/4 mile -- unless you're bracket racing. But, you could do that now. Once you drop $5k to get 1.5-2 more seconds, you'll get used to it quickly and wonder why you couldn't have been happy with that money in your pocket.

The motor you have now FEELS like an 11-second motor from light-to-light. But, look at you. That's not enough. If you really go down this road, I'm betting $10k is what you'll spend before you're happy....or give up.

 

If you're willing to mod your hood. Most people would agree the Holley Stealth Ram (aka HSR) is as good -- if not better choice.

It's cheaper, retains a bit more low-end torque, and has a certain visual appeal.

 

Been there,done that. If it feels good as a DD and your happy and "impressing friends" without timeslips - Leave it!

 

Miniram rocks but I think its going to take some good heads to go 11s.

 

Exactly. And, it'll take something else (besides heads and MR) to get into the LOW 11's.

Maybe you could dump all the body panelling and race it as a light-weight go-cart! LOL

I'm not really interested in a hood mod. I wanna keep the outside as stock as possible.

I'm gonna start with the mini ram. I will probably start in Febuary and i'll take it from there. But Heads for the future any thoughts?

 

I have a similar setup...lpe 219, ltr, headers, etc. Its capable of low-mid 12's. I've had faster cars, but this one feels faster than any of them around town. Very fun to drive and appears stock under the hood. Don't go to the track much at all so I dont care about timeslips. People think this is an 11 sec car from how it feels when I give them a ride.

 

FYI a stock 88 with auto has less than 245rwhp
So you are already 50 rwhp over stock.

More air in should get you closer to your goals

 

Actually a stock 88 probably puts down 200-210 rwhp so he's more like 90-100 rwhp over stock

 

& rather quickly too.
