Dynoed the Spirit R/T

[4sfed 4]

After putting my new R/T back together (re-ringed the pistons, new rod bearings, valve job, etc, etc), and with about 350 miles on the engine, I decided to take it over to John's and see what she'd lay down. I was pretty curious as to whether or not everything went back together 100% and that I was making the proper amount of power. The car felt good, but the butt dyno sometimes lies.

The car was all stock except for a 3" turbo back exhaust (no cat and Race Magnum muffler), a grainger valve for boost control, an adjustable fuel pressure regulator, boost and EGT gauges, some light cleaning up of the ports and exhaust manifold, and a Pep Boys cone intake filter. In my usual fashion of keeping expenses low, I tried to do everything as reasonably as possible. Ive got $1500 in the car, plus about $400 in rebuild parts for a grand total of about $1900.

Yes, I am a typical Turbo Dodge cheapskate. But, the car is ultra clean and looks damn good for a grandma-mobile.

I wanted to keep the boost low to start just to make sure things were OK.

The first run was at 10 psi boost. (Stock boost is 11 psi.)

http://mysite.verizon.net/res1elpe/10%20psi-3rd%20gear.gif

I added about 2 psi boost and ran it again at 12 psi.

http://mysite.verizon.net/res1elpe/12%20psi-3rd%20gear.gif

Eventually, I got greedy (as usual) and tried to dial in more boost. Well, the vent orifice on the grainger valve was too big (and I didnt have any smaller ones with me), so I couldnt dial in the boost I wanted...all I could get was a wacko boost spike (18-19 psi)and a quick drop right back to 12-13 psi boost :x The spike started to show up in the lower boost runs, but it was much smaller, on the order of 2 psi, i.e. on the 10 psi run, the spike was to about 12 psi.) You can see the boost spike and boost drop pretty clearly in the plot below.

Ah well....all and all I was pleased. Im pretty sure I can crack 300 whp on the stock turbo and IC with a bit more tuning.

Congrats, You better be at Track day and make a good name for the room ;)

Jeff better make a good name for the room too :P

BTW that RT is beyond clean, was that Warren's old RT?

Yep.

Super nice sleeper....:thumbup:....I was the one at the shop in the busted ass Audi TT....

[emodsm]

very nice mr larry!!! i am still in search of the perfect turbo dodge!!

[FearThe4Doors]

yeah yeah.. ive seen those pics way too much larry!! :P

i still have to leave the computer and cry when i see it!

My spirit is on a good diet... the rust isnt getting better on it, so i'm starting to cut while the days count down. The drivetrain and suspension will find its way into my CSX eventually, but will be with a 5-spd. Then in the future it looks like it will grown an extra cam! :o

Hopefully the guy in Ocala with an R/T will show too

That was a nice car!

IMO, the "perfect" TD would be an Omni with a 16V swap into it. Id love to do it, but it would kill me to rob my R/T of its innards since its in such good shape. But, putting the same driveline into an Omni would be like picking up 75-100 hp!

[mpbiv]

Why rob a TIII car when you can retorfit a neon head to a 2.5 block :twisted:

[FearThe4Doors]

or 604 the bitch!! :evil4: :evil4: :evil4: :evil4: :evil4:

[ACR2NV]

very nice run Larry i'll be sure to pass it on to Warren hes now the proud grandady of a baby girl...everyone was expecting a boy so it came a shock...congrats to them all. Im gathering my parts for the 86 glhs should be done soon i hope...

[taka86fc]

it' very nice. i'll have 16V head someday. i hope i can find one

Because its a thousand times easier to drop the T3, engine harness and all, into the Omni!

Well, if you DO strip the RT of its engine...... here i go again... oh, nevermind... :P

If I only had an ultra clean GLH or GLHS body to drop the T3 into Id probably do it........

[FearThe4Doors]

i know of one that might be for sale... its up in zephyrhills... it has a little wing on the back, nice silver color, used to answer to the name "4SFED"... hehe

[CrazyMoparGirl]

That one is not for sale :lol:

[ACR2NV]

what car is that?

[FearThe4Doors]

oh come on lori! :p

[mpbiv]

You mean to tell me you only have one Omni Lori, uh oh.

[CrazyMoparGirl]

No I have 2 :D

[FearThe4Doors]

but one is an ultra clean GLH or GLHS body to drop the T3 into

But I don't have a T3 yet ;)

[ACR2NV]

i think Larry was hinting at something though

[mpbiv]

All this turbo talk is driving me mad, anyone wanna donate parts to the MoRice Turbo K project? Tax deductible I bet ;)

I'll put your stickers on the car :lol:

[FearThe4Doors]

i think it was me doing the HINTING!! LORI!!!! lol..

Buy my 2.5 dammit!! Complete top to bottom! With the built auto!

[mpbiv]

how did you get buy from donate?

[FearThe4Doors]

umm.. tax deductable.. tax return.. money coming your way.. buy my engine :)

[FearThe4Doors]

:wink:

i dunno Larry but i just cant grasp how a stock RT can run those numbers at such low boost i mean are you saying you were only running "10psi" with a spike to 12...i mean the numbers are impressive but the fuzzy math isnt.....what is it come clean...how much boost you running?

Nothing to come clean about! No fuzzy math!

The car only has the things done to it that I posted above. The key is ditching the horrible factory exhaust.

To give you an example, a bog stock R/T on the same dyno made 186 whp / 200 ft lb. Stock boost is 11 psi. The factory exhaust necks down to 1 7/8" in the rear! You can imagine how that chokes the engine.

So by basically ditching the factory exhaust and cleaning up the exhaust manifold and head, you can pick up over 40 whp while still running a tad less boost. To be honest, Ill bet 90% of the gain was from the exhaust alone with the balance from the light cleanup of the head and exhaust manifold. (I was too lazy to even touch the intake manifold.)

My car had the 3" exhaust with no cat and a very free flowing muffler (Race Magnum.....aka LOUD!), a cone intake instead of the factory airbox, some very light clean up of the exhaust manifold and the head ( I spent about 2 hours with my dremel doing both pieces), an adjustable fuel pressure regulator, a fresh valve job, and thats it.

Im hoping to go back to the dyno shortly while still on the stock turbo and IC and make some higher boost runs with the +40's and see what I can eek out.

[FearThe4Doors]

right. larry hasnt fooled anyone. there's no doubt in my mind he made those numbers on that boost. The lotus head is superior to the 8v head in flow. Look at the hondas, they only run 10psi where we have to do 20+ in the 8v's. I also couldnt agree more on how crappy the factory exhaust is. On my 86 non intercooled early T1 Daytona, just gutting the cat alone gave me an extra psi or 2 of boost. and that was still keeping the tiny tailpipe. Turbocars show HUGE gains on the exhaust side

See! Even Jeff says so!

This Lotus head kicks @#$!

I also couldnt agree more on how crappy the factory exhaust is. On my 86 non intercooled early T1 Daytona, just gutting the cat alone gave me an extra psi or 2 of boost.

My boost jumped a solid THREE psi when I ditched the factory exhaust with absolutely no other changes.

Heres some more fuzzy math for ya! This is like advanced Calculus compared to my runs!

LOL! :lol:

2.2 Turbo Dodge with Maserati 16V head at 23 psi boost. Thats what 443 whp looks like boys.

zoikes!! You got the RPM overlay for that?

And thats Diogo right?

HOLLY SHIZZIT!!!!.....now that one i will not dispute!...*wipes himself*

Larry i wanna see the torque show us! show us!...NOW! *ready for next cleaning*

I dont. But, you can figure that out pretty easily as the run was made in 4th gear.


And thats Diogo right?
Yes.

I dont have the torque plot for that run. But, I may have it on my other computer at home....Ill check.

In any case, peak torque was something like 414 ft lb if I recall.
