It's not that...its that its still a relatively new car...and so lots of the regular variables in such comparisons that we all remember are still not yet ingrained into the minds of our culture yet...

Best we have to work on is the historical experiences and information...

And 400+ HP usually is problematic...heh

Third Gear no clutch dumping.When I was next to him I already was im third. I just went WOT.

Some FYI notes from my weekend trip to Melbourne, Florida and back home (around 2 hours each way).

I strapped a temperature sensor just above the intake/exhaust engine manifold area of the engine bay. Note that I’m currently my car has an ExoticSpeed header wrapped with plenty of heat wrap material. Ambient temperature was 90 degrees before I got on the highway and it registered 153 degrees while at idle. Once I got on the highway (I-4) I waited until the ambient temps got to 95 degrees while cruising at 77 mph and AC on. The engine bay temperature was at a steady 138 degrees.

I also connected another multimeter to my OEM 12v lead to my MSD ignition coils just to monitor for possible voltage drop while at high rpms or WOT mode. My MSD ignition coil ground wires run strait to the negative post of battery while the internal igniter ground wire are attached to the car body. I was thinking of running a wire from the positive side of the battery to the MSD ignition coils (using a 30 amp relay) in case of voltage drop. Well I’m happy to report that there was no significant voltage drop throughout my whole trip that included various driving conditions. For example cruising, idle, OEM bose radio full volume, AC set at full power and a RT 528 Beach Line WOT sprint to 135 mph. Voltage fluctuated between 14.15 and 13.83. Therefore no positive 12v ignition wire modification is needed.

Lastly, I purchased a quart of RC model 33% Nitro methane fuel and mixed it with my Snow Performance Boost Juice (50/50) at the rate of 1 cup per gallon of Boost Juice or basically half a cup of Nitro methane to a half gallon of Boost Juice. I mixed it for about 15 seconds and poured into my windshield washer/meth fluid reservoir. Results…Fing out of this world. I don’t know if is the combination of the header, methanol nozzle positions and now the methanol/nitro methane mixture but now the car accelerates faster and stronger than ever before. To give you an idea, Bastage and I were sitting at a traffic light side by side and upon the light turning green we both took off like bad out of hell. I spun the tires almost all the way to second gear and on second too. Later Bastage asked me if I had disabled the DSC. Negative, the DSC was on; in fact I never disabled it the entire weekend. I feel like the DSC tries to cut down the power but it is too much for the electronic circuitry to act upon it (this is just my opinion since I’m not to familiar with the DSC system).

I’m planning to do a dyno and a ¼ mile track event next month to find out for sure if my butt dyno is accurate and to determine for sure if there was a whp gain since my last month dyno when I did not have the header or methanol/Nitro methane mixture.

Uh, don't do that.

RC fuel has castor oil in it. A LOT of castor oil

marsredr100

iTrader: (1)

Yes, I took that under consideration before selecting a brand with the least amount of castor oil in the fuel blend.

http://www.traxxas.com/products/acce...es_topfuel.htm

In fact, the fuel does not feel greasy like my other 20% Nitro methane brand fuel that my son uses on his RC car. I also did a pour on the floor and burn comparison. The 33% brand left hardly any oil residue after the burn compared to the 20% fuel which left a very noticeable film of oil.

Lol why not just use methanol with less water?

MazdaManiac

iTrader: (3)

Nitromethane has such a low stoichiometry that its value as a fuel in this application is completely negligible as well.
Methanol is about 6.5:1, but nitro is only about 1.7:1!
Under normal boosted combustion (perhaps 11:1 or so), a nitro blend is so lean that it isn't doing anything.

VarneyMazda

Well that's what I thought but I wasn't sure so I didn't want to speak on the topic. Sounds like probably the snow mixture is doing the work and he's losing power from the other stuff.
If Rc fuel worked well you'd see people use it but this is the only time I've heard of it

MazdaManiac

iTrader: (3)

Well, the nitro will cool the intake charge, but its really volatile and not miscible, so it will settle out of the water in the meth/water tank.

Flashwing

Speaking of Dyno sheets, has anyone with a pettit been able to dyno their vehicle and has sheets to show the power difference?

I've seen posts in the past with members boasting increases as much as 300 whp but I've only seen dyno sheets from Pettit.

I've been trying to collect some data on the supercharger but no body seems to have it. I've only seen data from Jesse's RX8 here in Phoenix.

MazdaManiac

iTrader: (3)

Did Bastage really say that?

OK, Bastage. Teach me how to read a dyno sheet.
Please. I could use your enlightenment.
Pettit's dyno (as posted here and elsewhere) is a fraud.
There. I said it.
No insinuation. No "suggestive" language.
It is not numerically, scientifically or practically plausible as posted.

Start a separate thread. Use this one. I don't care.

Just like Flashwing stated, I'd like to see some real data. Real sheets, real logs, real numbers.
Its just a bunch of hot air in this thread - literally and figuratively.
I've seen the dynos from the north east. I know several of you have dyno'ed at or less than stock with this thing.
I've seen Jesse's. I know what he pulled - I was standing there when his car made that run.
I've laid my hands on a bunch of these systems and I know what they really do in the real world.
Someone show me a dyno - a real dyno that follows the science - that shows the claims made about the output of this kit are substantive.

Otherwise, I call BS.

Guys,

I really don’t know if the Nitro methane is increasing power or not. Only a dyno will determine that. I do experiment with my car and sometime it work, sometime it doesn’t. Regardless my next month dyno session will include a variety of methanol mixtures and I’ll post my finding afterward. We all know that sometimes what looks good on paper does not equates the same results in applications. I’m not an expert, I just learn as I go. Sometimes the hard way.

Bastage

iTrader: (1)

For those of you that haven't read it, here's the post that caused him to block me. As far as dynos approaching 300 hp; I've dynoed in the 280's, Juan has dynoed higher. Roland/Cam have dynoed in the 300's. This kit is capable of it, but if you want to go ahead and believe a guy trying to sell his own turbo kit, and that has been plain belligerent to all things Pettit since BEFORE the kit was even released, then enjoy the KoolAid.

Enjoy:

No discrepancy, it's either a (sub?)conscious bias against Pettit or you cheated your way through elementary school:



As you can see from the graph and my chart, the torque curve is relatively FLAT from about 4000 RPM all the way until 9000RPM. An increase in RPM with a relatively flat torque curve will give you a HP INCREASE. It’s simple arithmetic. Go back to school.

There's nothing wrong with Pettit's dyno equipment. Make up something else.

You're forgetting that the RPMs are increasing too... !@#$ing DUH

By that statement, you're saying that if a jug of that Koolaid you're drinking has a leak in it and it is leaking at a rate slower than it is being filled, it will actually have LESS Koolaid than it began with at some point in time. That logic is not compatible with reality, unless you have some kind of Magic Jug.

HP = (RPM X Torque)/5252

Where's the discrepancy?

While I'm sure Cam doesn't give two ***** about Jeff's smears towards his product, I as a very happy customer do care.

He was damned rude towards Bill Hart when he was trying to support the EFI Dude people, and has constantly bashed Pettit (both of which are uncoincidentally directly competing with the two products he is known for selling). His unconstructive/*******/bullshit/smear posts are concrete proof of his lack of professionalism. What vendors on here present themselves the way he does?

Because of this, I encourage people not to do business with him.

eviltwinkie

This request does not at all seem that terribly hard to do...and if I remember correctly, we have yet to really see anyone post a dyno...

Anyone? Buller?

regardless of whether he may be an ***, in this for his own personal gain, or anything else.... he pressures a valid point, where are all the users dyno's?

It amazes me the latest route this conversation has taken simply because Moon posted up some old news regarding ignition coils.

Jedi54

iTrader: (7)

Not to try and add fuel to this fire cus I don't really care either way but that is a question I have long pondered.

It seems as though Pettit moved quite a few of these units but I haven't seen many dynos. Could be as simple as some users just don't care enough to post their figures here.
It's mind-bottling

haa haa haa....

I'm not being rude or a smartass here, but have you guys actually been reading this thread? That's another thing that cracks me up about Jeff; he's such a hack that he just invents bullshit to try and justify his bias, and people just blindly swallow it. Here's Juan's dyno from last month:

https://www.rx8club.com/showpost.php...postcount=2120

It's there, you just had to look for it. I haven't had a dyno printout/image to post up since I got the kit last year (was 260.5 @8500rpms on the int-x), but the last dyno I did back in April my car hit 283 @8000rpms, and Juan's car hit 289 or something like that. This was in the evening (mid 80's temp-wise), I was just running with an RP supercat, Juan was running meth with no cat. Juan and Roland were there. Since we're all running similar tunes, with similar setups, the dyno plots look pretty much the same; regardless of whether they were done at Pettit's shop or at whatever shop Juan went to in Tampa.

Agreed, but historically that's how it usually goes. Someone will try and share something and Jeff takes time out of his extremely busy day to try and insult the person.

It's actually funny. I think the first time Jeffie started **** with me (over a year go, now) was after I suggested on some thread to someone that they stick with the stock radiator, and not get a Koyo. I was only conveying information I had received from Cam, because he had shared with me how he had been through a couple Koyo radiators and discovered many months before that they were crap.

Anyway, it turned out that Cam was right, but since he doesn't live on this forum like Jeff does, the world had to wait 8 months for Jeff to discover that for himself (Jeff eventually dumped his Koyo for a stock radiator).

It's been a pretty consistent pattern.

I have posted my Dyno Charts on this thread and on the thread about the renisis engines with most power

Bastage

And Jeff knows this, but as long as he states that they don't exist, his fan-club will believe it. That's the beauty of having all damned day to clown around on here. Looking forward to seeing that 325rwhp plot.

eviltwinkie

Actually no I dont read it...between the rambling and the BS floating around in here I generally ignore this thread...so its pretty easy to see why we missed the dyno post...

eviltwinkie

Ugh...its the BS like this that makes me say...

Bastage

iTrader: (1)

Yeah, and all that BS can be traced back to one guy. I suppose if people weren't so quick to swallow the BS that this one guy seems to float, then maybe there would be lots less BS around here, and no one would have missed that dyno post.

huh?
