Going For 800 Rwhp

[05stroker]

Oh no, not that. I love how the RPM’s ramp right up and it seems to always stay high up in the RPM’s where the power is at as the “clutch” comes in.

I don’t know if you have ever ridden a aggressive snowmobile (sled). Mine is “clutched” so when you are at a dead stop and go WOT it immediately jumps up to about 7200rpm and then as it accelerates to its top speed of about 114mph it only gains another 800rpm for a total of 8000rpm. The variable clutches in sleds are set up to always have the motor “on the pipe” by changing the ratios between the two clutches constantly. On a basic level they have a CVT transmission.

Your car kind of sounds like that in that dyno clip. It gets right up there in the RPM’s and seems to make it’s run without having a huge RPM sweep. It sounds really pissed off!

That's the power of the PI 3500 conv. along with a stroker with custom grind cams and an F1a. The cams in the car make a lot of low end power. I actually have them retarded some now. I had to degree the cams to find that comp had them off a bit from what I was wanting. My dyno sheets posted here in this thread actually look like a twin screw dyno sheet. The tq comes fast and the hp plato's at about 5k and stays there to 6800. I guess that's why I was able to 1.5 my 60ft with the 20" drs. LOL

Looking great!!! Believe me I know what it feels like to get it running after all this time, I went through a similar time with mine.

Yea, it has been a long time coming.

Congrats man, glad to see your hard work finally paid off. I'll have to check it out some time too since I live somewhat close.

I will be doing my shake down passes (and learning to drive the car again ) at Dallas Raceway this spring.

I plan to do all the tuning on the road this time with "lito" tuning the car and then make a few dyno pulls just to check the power.

Where is that posted at? I can't find it.

Here is the pump gas one.

Red X of death!

Here is another one on race gas done in another part of the country.

Here is the race tune done here.

Very nice , this has been a long road.Cantwait to see how this makes out at the track .

That is a pretty flat torque curve for a Centri. Nice!

What sort of timing are you running?

Are you using a air to air intercooler? What are the IAT’s like. Does it heat soak or recover pretty well between runs? Have you had a chance to drive it around in traffic? Does it want to heat soak under those conditions?

I like how my car hits like a TON of bricks but the twin screw is a FURNACE! I already have a heat exchanger larger than the big Afco and it’s not getting the job done for daily driving. I’m working on a new exchanger(s) right now that is three times the size but I’m not even sure if that will get it running as cool as I would like it. Next step is to chuck the 2.6L blower and put a 3.4L on so I can slow the blower speed down at cruising RPM. If that doesn’t work I’m thinking TT compound boosting a stock GT500 blower. What a PITA!

Wondering “The other half lives” making big steam with a centri.

Great job on the car. I hope some day to have the time and patience to make mine as clean as yours is.

Maybe I will have mine done by then too and I can do some shakedown runs with you.

I hope the new setup makes that kind of tq per hp.

I was running 16 deg on the HPP pump, 23 deg on the HPP race fuel, and 20 deg on the Brooks Speed race fuel.

It is an air to air. It cools down pretty quick.

As for the traffic driving, there is no such thing here. LOL

I have drove it to Dallas a couple times in the past but, that was on Saturdays.

Maybe I will have mine done by then too and I can do some shakedown runs with you.

Sounds good. Im sure I will look like an ass for a little while though. Its been a long time now. Im going to be "that guy" with the 800 hp 12 second car for a couple passes and everyone will keep thinking something is wrong with the car when I let off at the 8th mile , 1000 ft ect. LOL

Lol, I'm sure you will do fine after a few passes.

 

[05stroker]

Lol, I'm sure you will do fine after a few passes.

Yea, my biggest problem is actually being able to watch the gauges and let off. I just want to go fast and scare the shit out of my self. LOL

That thing is awesome!!!!!!!!

what boost are you running on pump gas/ race gas. what do your iats look like? what a2a intercooler are you running?

Thanks

This is a whole new setup, it will be a few weeks before I know those things.

I will be about 18-20 psi on pump (low timing) and 25-27 psi on c-16. Then the N2o will be added.

I have a few things that will only be added after the base tune and dyno runs are done.

1. MSD Dual DIS4 with Autolite HTO plugs gaped at .040 (with the same boost levels) and (I'm at .032 now)
2. Crankcase evac. setup
3. Add the 50 shot of N2O mentioned above
4. Then the Comp 127550 cams

If anything else is needed after that it will be done with the N2O for the track only.

Do you have any pics of the cold air intake on the car? Contrats on getting this car going again. Lito will take good care of you, he's a real standup guy.

 

[Bobby]

dont use c16 use this http://www.renegadepro1.com/Renegade/?page_id=9 use the 118 nitrous. my tuner did a test with that and c16 and he picked up 30whp and 35wtrq with nothing changed other then leaning it back out to the c16 af because it was even 10% richer.

1. MSD Dual DIS4

Tell me more about this. I like the sound if "high test" ignition stuff.

Here is some info on it.

It should allow the plugs to fire with a wider gap and rev faster. This also has a built in 2 step and rev limiter along with the ability to kill the ign. system. One thing to note though is that this setup has history of failing units. The newest versions like mine are now since I sent them in to be updated to the latest and greatest they can be are supposed to be more reliable. When I bought these units the they were bad. I sent them to MSD along with the tach adapters to be tested. They said the processors were bad and replaced them with the new updated ones.

New this setup will set you back about $1500.00. It is (IMO) for maxing out the fac. ign system for a max power setup only .

 

[BruceH]

That MSD unit is interesting. I just scanned through the pdf. If I understand correctly it's not a stand alone, just splices into the coil wires and still uses the factory ecu.

By any chance did you do any comparison to an LS coil conversion? I'm nowhere near needing more spark but am curious about the solutions in case I ever find myself facing that problem. 27psi is going to put your ignition system to the test!
