HSR Finished !!
Here it is & it runs strong. Can't wait to get to the track. More pics on my website. Sorry pics too big won't transfer.
Hey Rick.. I'm considering the 950 commander ECU for my setup. I already have a SD harness and 730 computer in the car right now. Is the swap difficult ? What do you have to do exactly ? Summit and Jegs arent very specific about that.

The swap wasn't the hardest thing I have done. I did the swap back in June when I still had the Super Ram. I bought the 950 for the TPI. The wiring harness was too short to go through the door pillar, ala stock, so I cut a hole for it, in the fire wall, under the heater box. I put the ECU in the stock location. It took some fabricating & time but it was worth it. Note, I removed my AC evap core & modified the heater box for more room. You will have to provide an alternate method for TCC lockup, the 950 doesn't have a provision for that. I also purchased the knock sensor kit ( it uses the stock sensor & module) & the cooling fan kit. The 950 is a good setup, the best point is you can tune on the fly.

well acording to the results,(useing before and after mph) useing this
http://www.gordon-glasgow.org/hpcalc.html
and this averaged
http://www.prestage.com/carmath/calc_hpformph.asp
I picked up 68hp(average hp ) with the swap from a ported TPI with siamesed SLP runners to the HSR, thats average hp which means the PEAK hp was higher, and I know my gearing sucks at matching the peak torque curve. but also keep in mind my full roller 11:1 cpr 383 was strangled for airflow above 4500rpm with the old TPI (even ported with larger runners) where the new HSR pulls to 6500rpm easily now , so is as much as case of the OLD TPI being junk as it is the new HSR being a great intake. two dynos I have seen show the HSR loses power under 4000rpm but more than makes up for the slight low rpm loss above 5000rpm and by 6000-6500rpm walks away from all the other intakes tried so far by almost 30-90hp (DEPENDING ON WHAT IT REPLACED)

HSR Track Times
Well as promised here are the track times from yesterday's test & tune.
Temps in the mid 70’s, rising barometer, 1400’ above sea level.
Best Run 09/28/2003 Stealth Ram, AFR 195 Heads, Comp XR276HR
R/T .610
60’ 1.879
330’ 5.432
1/8 8.430
MPH 82.07
1000’ 10.997
¼ 13.145
MPH 105.27
Best Run 08/25/2001, with old combo, Super Ram, World Torquers, Lunati 216/224 @ .489 lift.
R/T .769
60’ 1.920
330’ 5.450
1/8 8.423
MPH 82.75
1000’ 11.003
¼ 13.194
MPH 102.66
The HSR setup needs a little more tweaking. The upper RPM range seemed to be starving for fuel. I am still running the stock 22lb injectors @ a fixed fuel pressure of 45psi & cannot increase the fuel any more above 5000 rpm in the software. Maybe 30lbers and/or higher FP ?

according to my computer, (asuming your car weighs about 3500lbs) the speed increase from 102.66 to 105.27 indicates a net gain of about 17 hp over the previous combo, once you get it tuned correctly and get the correct fuel/air mix durring the whole 1/4 mile run Im betting youll find even a bigger increase in hp. the super ram I had tested flowed about 45cfm per port less air than the steath ram flowed, that would require a boost in fuel flow to effectively use the greater airflow!

RickTPI - For your combination, a 24# injector is probably the minimum that you should be using. You need to get a wide band AirFuel meter hooked somehow otherwise it's very difficult to know where you are at.
I have found that with my MiniRam, the car runs best with 38degs total timing. This is with an 11.5-1 compression 383. A buddy of mine with a Vette runs a similar combo and his runs best with that timing as well. I also like to bring the timing in early.

try running your info through the calc on this site (bottom of page)
http://www.rceng.com/technical.htm
or here
http://www.z31.com/software/injector.pl
use a bsfc of .45 and a duty cycle of 80% max and about 43lbs of fuel pressure and see what you get for the hp goal your trying to reach
it may help narrow down the choices you make on an injector size to use

Damn you guys must be doing something wrong. My 91Z 350 Tpi went 13.11 at 101.6 with 3.42 gears ,zz4 cam, freemods, air foil, stat, marsh under drive pulleys on sportsman pro street tires and everything else stock. Had a 1.73 60 foot. I dont understand why alot of your cars dont run better. Im not ragging on your cars, just dont understand.

a large part of it is the 3.43 gears hes goT, most cars equipted with a TPI cam with 2.87-3.08 gears. that change to 3.43 rear gear bye itself adds a great deal to the cars ability to launch. my friends mildly modded 69 camaro has a TPI equiped engine and 4.56 gears and slicks, the camaro weighs about what the vette weighs and he stays right with me through first gear. now much of that is because my tires turn to smoke if I floor it but theres no doubt the gears help a great deal

I'd be interested about Christmas Time.

Glad to hear about the results of the SR. Definatly get more injector. SVO 30's have worked well in my 383. For the price you can't beat it.
Oh about the superram, I'm selling mine, I'm looking for a miniram.
Pictures of my superram are at www.geocities.com/leirch_
