I got my copy yesterday and opened it up to see a simple nice write up on an exhaust swap onto an 89 Formula 305TPI with a T5 behind it.

Maybe I havent been keeping up but i guess they did something with it in a past issue??

Anyway, the documented the gains and money spent. The owner is trying to get the car going fast for $10k uncluding the price of purchasing the car.

Id say thats pretty close to what most here would consider a "normal enthusiasts" approach to modifying their daily driver.

Should be an interesting project to follow.

You think?

 

Well im still under $10k, but nowhere near the ET I wanted

 

I guess it will depend on what they mean by "fast".

We all know the best way to spend that 10K is on a 350 :sillylol:

-Matt (still 305 impared, but making up for it with a brand X car.)

 

I have somewhere around $12,000 in mine, but not anywhere close to what ET I wanted to be at. It doesn't matter, I'm not done yet, and there are things holding me back. You shouldn't get discouraged with your ride, because one day everything will fall in place, and you will have a bad A car...

I finally got some pictures of my car today. I can't figure out how to post one on here though...???
Oh, how did the track session go the other day TPI_ROC?

 

Could have been better, could have been worse.


I think the entire track was weather impared, its 102° out right now (noon) and we have all the smoke here in oregon from the forrest fires.

But without making excuses i ran a 14.1 at 98mph
thats 13.88 NHRA corrected

I think the problem is my stock tpi, sitting on 200cc runner heads, as soon as that LT1 intake is installed I expect almost a .5 drop next time im out (cooler weather, and speed density)

 

I can promise you that you will be pleased when you get the intake on...when I got the miniram put on, it felt like a total different car...It has been about 4 months since then...loving it still.

 

I'm sure of it, Im expecting a miracle.


200cc runners = no torque
stock tpi = no horse power


so escentially I got nuffin


I need to drill out the distrib hole now and get a spacer made, then i gotta order the Tstat housing and make up some fuel hose and I'll be done.


I hope I get it pounded out before the season is over, if not its going to be a fun winter

 

Aren't those heads you are using iron? What are the specs of the cam you are using?

 

Yea iron sportsman II's

224/230 @ .050 112 512 lift

 

You will definately see a big improvement, especially in the upper RPM's. If you don't already have a stall converter, I would recommend one(if you don't have a manual trans.).

 

2,500rpm stall


The buildup was with RPM's and HP in mind, I expected the LT1 intake when i bolted the heads on, tahts why the cam has that duration.


I just need to get it ON so i can experience the powah


But 14.1 is relativly fun

 

TPI ROC,

You need a distributor spacer? Angled of course like I include with my conversions.

 

Yes indeed


I haevn't had a chance to see if any local machinists could whip one up.

This doesnt work with a stock TPI and stock converter. Running identical ET's as you, but heavier car. Same screwed up weather.

 

Huh?


I dont have a stock converter

 

John, I emailed ya

 

What do you fellas realistically expect for $10K? I mean a nice TPI 3rdGen could be had for about $2500-3000(in NY). That leaves you w/about 7 grand worth of mods.
I would imagine you could have a 12second(high or low)car for that kind of cash. Is that too much or too little to ask for, for 10K?

 

what if you bought the car new in 87 for 16,800... does that put me 6,800 behind?.....

 

Sorry, missed the 2500 stall above. Thats still not enough, IMO.

 

What the heck do you mean by "this doesn't work"

 

I have an 87 L98 IROC I bought for $3000.

With $7000 left over, here is what I would buy.

AFR190's competition port: $1500
NX nitrous kit with all the goodies $800
LT1 intake: $400
30# or 36# injectors: $300
224/230 comp eXtreme cam: $250
messing with PROM: cost of prom burning software

say up to $3500...

next: Vigilante converter: $700 ($4300)
BFG Drag Radials: $300 ($4700)
52mm TB: $300 ($5000)
Hooker long tube headers and 4" mufflex exhaust: havent chekced lately but say $1000 for all that ($6000)

Okay so you have $1000 to play with. take away for gaskets, ARP head bolts, misc hardware here and there. replacing O2 sensors, relays, etc. You should EASILY have an 11 second car right there. If not then something would be wrong.

Hey that was sorta fun.

 

What do I mean? Mismatched parts. A 224 cam isnt really a good choice with a TPI, its too much duration and is more for higher RPM power, past the useful range of a stock TPI. The power curve doesnt really start to pick up until around 3000, so theres no point in having only a 2500 stall, it needs to be higher. Thats what I mean by doesnt work.

 

haha
re-fug'n-lax

Read my profile, the 355 wasn't setup for the tpi, it was setup for the LT1 intake (Given the head intake runner size of 200cc) but the tpi was there, and gave me the chance to drive my car, no matter how slow. So now the 355 runs everyday and 14.1's with tpi, and my lt1 intake is slowly getting closer to done, when its on im sure my times are giong to dramatically increase.

 

I think you need to re-fug'n-lax jerself.

 

You're right

 

hey, whats the date on this mag? what month
