Good running L98

-hawks thirdgen ram air boxes

-maff is gutted (and new as well as o2)

-air foil is thier as well ($15)

-Ported SLP runners, partly siamesesd

-siamesesd plem

-portmatched base (my buddy who knows what hs doing is doing all the porting work)

-hooker 2055 kit

-magy cat back is their, no cat, no a/c

-And a TPI NOS kit 100 shot

How much HP/TRQ can I expect from my stump puller TPI.

 

the year

 

1988 IROC-Z TPI MAF

 

approx. 40 extra ponies plus nos

 

I expect awhole hella lot more than that.....

 

ok here it goes



hawks thirdgen ram air boxes - you need a ram air type hood to take advantage of this....

-maff is gutted (and new as well as o2) - maf is not a restriction on a mild 350 tpi build.... i hope since you have headers you have a 3 wire heated o2 sensor because the headers will have a hard time warming the factory one plug o2 sensor up and will cause the ecm to act crazy.. headers do not retain heat like the factory manifolds do...

-air foil is thier as well ($15) maybe 1 or 2 hp some say it helps others say no difference

-Ported SLP runners, depending on how much they are saimesed they will add power

-siamesesd plem - did you port match the openings the slp runners, grind down the egr walls.... should give you a good seat of pants feel as well as some power...

-portmatched base (my buddy who knows what hs doing is doing all the porting work) is it a factory gm base or aftermarket unit... either way porting the intake will yield increases.... you probably extended ur rpm band up a few hundred rpms... which is good..

-hooker 2055 kit good headers.... should give back about 20 hp back to the engine

-magy cat back is their, no cat, no a/c another good mod... should also give the motor back 10-20 hp..

-And a TPI NOS kit 100 shot

How much HP/TRQ can I expect from my stump puller TP

id say around 260-270whp and around 330-340wtq..... basically what you did is increased the intake/exhuast capabilities of your engine.... you made it easier for your engine to breathe which should give you a nice feel over stock that for sure... now to take advantage of that and take it a step further, a nice tpi like cam to go along with your mods would really make power and take advantage of your current mods...

 

what kind of gains are you expecting?

 

....well....hoping for 175 on 100 shot spray may bump it to 125 but no 150 shot for me. Stock heads and cam as they cost a lot of money....and labor....if any body has some vette heads for cheap im all ears.

I dont need a ram air hood as its a camaro...also should I take the fog light ducts out to use the fullsurfice area of the boxes for in coming air or leave the ducts to channel the air in (fog lights are removed)

 

-and yes all the intake will be port matched-

 

75 horse from those mods (excluding nitrous)is quite a stretch. Like everyone said before 35-40 hp seems more realistic.

 

Full bolt on L98s usually get into the 250-265whp range depending on condition/dyno/etc

Stock are 210-215 on a decent condition motor, some as high as 220's.

So you will likely only get 30-40whp on full bolt ons and you dont even have all the bolt ons yet.

I'd say 240whp on motor, close to 340whp on 100whp shot.

 

where would i find these 3 wire O2 sensors and how easy are they to install? im looking into some Jegs 1 1/2 in headers atm

 

i used this heated sensor
http://tpiparts.net/inc/sdetail/2028


i used this harness
http://tpiparts.net/inc/sdetail/2167


you can get a bosch one.... one of the wires goes to an ignition source... i have mine at the fuel pump relay in the back so its only on when the car is running.... That's a pink/black wire. The other one goes to any ground. They're both the same color and it doesnt matter which is which. The third wire is your signal and that goes to the O2 sensor wire leading back to the computer. its actually a simple swap if you know what your doing....

 

Expect 100 RWHP and you'll be really, really happy.

 

hmm, interesting. now if you were to use some sort of header wrap, would you still have to use heated o2 sensors?

 

Even with header wrap, i'd still look at installing a 3 wire heated o2. Its not hard to install.

 

back when i had just a single wire oxygen sensor with headers my idle was very jumpy and would not idle right and caused driveability issues..... with the heated sensor, it heats itself up and gets the computer into closed loop faster..... its worth the investment.... i dont use header wrap and some people hate them other people like them.....

 

HEY STOP JACKING MY THREAD ABOUT DUMB HEADER WRAP PPL!!!!

100whp+ would be nice. ;- )

 

thats what im hoping for!!! GIV ME SOME OF THAT!

but anyways....my secret plan is to beat a stock ls *WaT*

 

Depending on the model, a stock LS1 auto car can be mid lower 13's at 104-106mph. My 99 TA ran 13.4 at 104 in decent air conditions. My full bolt on L98 would run 13.3's at 101 in similar conditions. Thats bone stock LS1 to highly modded L98 setup in drag race trim That was only with 250whp. A 100 shot will put a hurting on a LS1 car thats stock. But i have heard T56 cars getting 12.7's with drag radials, nothing else done. Bolt on L98 with 100whp shot in drag trim with good slicks/converter should be mid 12's so you should have most stock LS1 cars covered.

 

Good, both my buddies are ls *what* lubing f3gz....and its ls *wHaT* this-that and the neibors dog....their always knocking me for building the stump puller. But thats the name of the game....use what you got and build fast not buy fast.

plus fat guys love torque!!!! :- O

 

Its hard to understand u.. but i wouldnt talk bad about ls1's. They are just a few simple bolt ons away from destroying ur car nitrous or not... they are incredibly fast once modded up... ls1s benefit much more from bolt ons than the Gen 1 stuff.. just a can only ls1 can put out 400 horsepower..

 

I know but I like tpi, I drive on the street and want a trq hungry monster to let loose in the middle of the night and feast on stang and those damn scoobies! (subies)

(plus I want revenge on this white suby with a black hood, no badges and blue lights...I was undefeated...V_V....and this was on my own turff.

sbc is in their plus I havent been taking good care of it this whole time to part with it. and I want to retain my numbers matching block. No money for fancy mans lsx....

 

hey hey watch the subie comments....i happen to be a 3rd gen guy that daily drives a turbo subie

 

ok....do we care, no....thats subies gonna pay........NOS kit is supose to be here friday....REVENGE WILL BE MINE!!!!!




- dont hate them, their just all over the place....and with those box wings....

 

There's also the option of a HSR, better heads as well.

 

mabye heads later, no hsr.

-also got the NOS tpi kit in their, ($385-ebay)

 

as of july 4th, motor loves the spray.... : )

Wheir are you white subie!!! I promise I wount bite....not that hard... = O


LOL

 

legacy GT buddy....no wing here

 

still havent found that white subie, dont worry men....ill get him.............

 

Oh what I wouldn't give to watch this race....... ...I got $5 bucks on the subie.

 

^^^^ LOl me too, Hey do you have pictures of your siamese and port job on the runners?

 

i would put money on the subie too....i can keep up with a LS1 car with mine

 

Im up to a 150 shot now. iv seen that damn scooby 3 times and every time hes going the other way and my bottle is empty (v_v). one of these....POW!!!! right in his box wing. I got runners back from my buddy and wheir going with a 5.3 swap so the ported plem and base are gone so ill just have my max ported 1/3 siameesed runners plus all the other stuff. drag strip 3 weeks! (hopefully) and to run the same budds stock ls1, 2.73, auto 13.50 car. Think I can hang?

 

I keep seeing that damn scooby and it pisses me off. Hes always going the other way....1 of these days im gonna pop a u turn and put a boot up his ***.

 

Annnd get your *** handed to you?

 

naw, I know ill have him this time...I wount have it wound to the top of second on a roll, plus I have my parts too.

YOU ARE MINE scooby!

 

Until you run out of nitrous.....

It's not smart to go hunting for modded Subarus on the street.

 

I hope by "pop a u turn and put a boot up his behind" you mean, "race him at the local drag strip, instead of fooling around in the street." And unless he's stock AND you hit the hundred shot of NOS, you'll probably lose anyway.

 

you may really want to put rockers and an adjustable fuel pressure regulator on it to really get the most out of the mods you have done for cheap.

 

We dont know if hes modded...but I did run him with me starting at the top of second....(yea, I know but its was quick instant that I saw him under the cover of darkness....<---dont mind that lond story.) he didnt pull away that hard though....I know with the GOD spray ill have his *** thus ending my vengenance and getting my perfect K.O. (undeafeated) record back.

---also I have plans to get another 10lbs bottle and hook the 2 together if they fit on the 1 seat bracket.

 

You should just take after the Scooby and boost yours since it's apparently a street car. My daily driver '01 Mustang GT has this little Vortech V1 blower waiting to go on it, already has a T56 swapped in, Centerforce DFX (To be swapped out for a Spec P trim twin disc whenever I feel like spending $1,599 on a clutch), as is N/A with no launch at all I do 60 MPH in the 5 second range on 18" wheels, 100 comes up in 13, runs pretty good. Non intercooled with the V1 I'll be around 430 crank HP, 360 at the wheels.

Plan is to build an intercooler setup not long after I have it installed, do some head porting, throw fresh gaskets on to be safe, stud it, and try to have a reliable 400 RWHP daily driver until I can afford a forged shortblock.



Eventually going to build a boosted 383 for the IROC also. Got the perfect candidate, a 4 bolt iron block sitting around.



So you never know, that Subaru might be modded kind of heavily. But anywho, hopefully you do get him. Just don't get too confident, they're quick man. I have the idea of picking up an 04-05 STI floating around my mind.

 

Idk my areas pretty working class....anyways my plans are to eventualy swap a 5.3 in and hook my juice up to it and some other stuff. I should be leaven asses busted all over the place. also a few late 60s novas have showed up in the L-W...more blips on the radar. ;- )

 

5.3 I hear? My plan is the same, just a Ford 5.3. Boss big bore iron block with a 4.6 stroker crank. I believe 3.750" stroke with roughly a 3.700" bore, to come out to 5.3 liters.

Wanna go even bigger with the IROC. 6.3 sounds about right.

I actually don't have much money either, just been saving steadily over time. I only have $4,000 total into my whole T56 setup from flywheel to driveshaft, plus the complete Vortech setup. I shop used and bargain even more.

 

Wow... And I thought the F&F fanboys were gone considering street racing as died off so much here. If you wanna prove you're the better driver tell the scooby guy to meet you at the track. Equal conditions, no launch advantage from beeping a horn, all it is there is better driver/ better car > all. How old are you dude? 17?

 

i might be sounding a little mean here and forgive me for this but after reading this thread i came to the conclusion that the original poster sounds really ridiculous... hate to break it to ya but your car is not that fast without nitrous... so your telling me it took you basic bolt ons and double the cylinders plus nos to talk bad about a 4 cylinder turbo car????? where im from many people consider it cheating and a poor way of getting easy power.....people laugh at guys who use nos and say they are big, as soon as you run out of nos then you back to the 260whp car. if you want REAL power then step up to a supercharger or turbocharger but dont boast how bad you are with nos because its another way of saying i have a weak car without nos to many people who live where im at... just about any performance car made today will run all over your car... granted my car isnt the fastest thing either but coming on here saying your chasing this and that and radars and crap makes you sound like a ten year old... (no joke) i mean if you read some of the things you wrote you really sound childish......

 

I agree with 88fastgta. This statement right here in bold made me laugh. Def the most sissy stuff I've ever heard. I highly doubt he's went "undefeated" either unless he only pics fights with stock civics.

 

260whp on a v8 is not something to brag about.... its somewhat ok for our cars but there are PLENTY of 300+hp cars from the factory today... with todays car even standard sedan cars can keep up with our cars.... technology has replaced the "no replacement for displacement"....

 

Adding cubes is still the easiest way to add power (short of a power adder). ...and remember you're only talking a 350, with stock like performance. An L98 would hardly be my argument for "displacement"!!!

....but yeah, I know what you mean.

 

I'm confused... how is NOS considered cheating, but a turbo or supercharger isn't?
