Anyone ever hit 500rwhp on pump with a GT4088 or close to it? As soon as my car gets done I'm getting it dyno'd/tuned.

-GT4088 journal bearing (more airflow than gt40r)
-Peakboost topmount Turbo Manifold
-Peakboost downpipe
-GReddy 3 row intercooler
-Ultimate fuel system from rx7store (850cc's, 1600cc's, rails, fpr)
-Big street port from Adkins
-Ported UIM
-Ported exhaust
-Water/Alcohol injection
-Dual Oil Coolers
-Innovate wideband

 

I don't think you'll make it with that turbo. (In a perfect world and set-up, that turbo is capable...on a rotary...at least that's what the math game says)

there are a few dyno charts floating around...search, and you'll see some people haven't broken 400rwhp on pump gas with that turbo.


what's up with everyone's hard on lately for 500rwhp?

 

They didn't have a good setup then, i made 380 on twins without half of those mods.

 

Then go make the 500 whp on pump and then show us. When people say pump, means pump alone, not with alcohol injection or some other form of detonation supressor, but if you mean pump with alcohol injection, then yes people have done 500 whp, I believe rice racing has.
500whp does seem to be the magic number lately though.

 

I will. Yes I mean pump and alcohol.

 

Well, that's not "Pump Gas" now is it ?

 

LOL....hey Eric, hows your new project coming along?

 

Slowly but surely

 

Well unless he used a pump for the alcohol!

 

Right on!!

 

why is it that "when people say pump, means pump alone"? i dissagree with that. sure, alcohol or water injection would be needed, but its just another mod...as is anything else that prevents detonation (actual IC, Tuned ECU, etc).

to me, it would make much more sense for pump to mean what it suggests...PUMP! Just fill it up at the pump and go, no need for higher octane fuel. just IMO.

 

Pump alone, how many ways do you want to put it, its just what it means, are you not being able to comprehend this??? Alcohol is ANOTHER TYPE OF FUEL you adding to the mix, and you have to tune for it, so if you use a map and add a bunch of alcohol, you will be rich and have to change that map from a PLAIN pump map to one with a map tailored for alcohol injection.
Alcohol IS a HIGHER OCTANE fuel, MUCH higher then 91 or 93. You even stated, to make those numbers, you would need it....not on pump alone, but its your opinion and we all know everyone has them.

 

Alcohol is another power added, plain and simple. Nothing wrong with it, just stating what it is.

Might as well pill it to kill it.

 

dun....dun....dunnnnnn then what would you call it if you do like rice racing and just add a crap load of water pre turbo? Why are we arguing this point again?

 

Washing your motor? Hell, I don't know


Most people wouldn't understand in the first place so I doubt it matters

I still think aux injection is lame, just run alcohol and spray the house down

 

I know! I know! I know!
It's called Water Injection!

 

hahaha no ****. But I tell you what, it does alow these guys running on street driven single turbo setups to boost more than thier usual 15lbs for reliability reasons. Now they can safely boost a lot more than that without the need, complication or expense of going all out alcohol or straight c16 race gas. I was going to be this guy however the more I get into the track thing the more I understand I would like to keep my motor for a while so I will be filling my tank up with the 112 octain at the track as well as injecting water and or alky.

lol alright smart *** I was just stating a point, haha.

 

It was a question, seeing if anyone else made 500 on pump with this setup, don't need to be a dick.

 

well on the kdrotary website he says he is doing a sponsor car with 500 or close to it on pump gas
you can go to the website and see for yourself
plus i talked to the guy i live near him and he really didnt start it yet but that is his plan

 

there are only a hand full of people with set-ups running 500rwhp...let alone on pump gas.

now on the another hand there are hundreds who make threads, listing mods, and predictions.

We will wait here and see your results.

 

yes multiple times

The only fuel I use is pump, FYI water does not burn and hence is not classed as a fuel :P

500rwhp (in your dynojet language) is dead easy, well if you know how to do it i should say its easy

To ******* who dis AI? (my form being water) thats the same rubbish BS attitude/opinion that classes your ingnorance up there with pole smokers like corky taco bell. dont confuse knowledge and engineering fundamentals with hype and opinions. As Dirty Harry would say: "Cant respect a man who does not know his own limitations"

p.s. spraying water is no different to running a charge cooler, or another device to increase performance... to class a FUEL it needs to have an energy content value, and last time i looked water had ZERO

 

Dont misconstrue the point I NEVER said water was a fuel, I said ALCOHOL WAS :P, and I was using alcohol injection as my example which is better IMO as it actually uses both properties of cooling the combustion chamber AND intake temps...after spraying methanol, the upper intake plenum was cool to the touch where just spraying water wasnt.

I never dissed any AI in this thread, all I said was running straight 91 pump gas with no additional detonation suppressors would not yeild 500 whp honestly. If it were done with straight validity and actual proof, then props to them and credit is due But again, running around 20-21 lbs boost, you are already super heating the air if run on a relatively small compressor.

I like the idea of AI, and if had an issue with money, I would probably be using, but I dont, so I just run straight race gas, one less thing to worry about if the AI fails, ya know

FYI:I had at one point ran water injection and liked it, but then made the decision to just run race gas.

 

Its possible, but you'll probably need to run more boost than you'll feel comfortable even with AI.

 

So a validated question would be, is it possible to make 500 w/ 100 octane? I know a few 76 stations that sell it at the pump, so if you where to make 500 with no aux injection would you be validated in saying I made 500 on pump gas alone and would that be considered a title worth having? With the technology of todays turbos why has no one made that mark on pump gas yet? Granted I know running aux injection is more for safetly, longevity and reliability, but its not realistic on a daily driven or every other day car. Is there no other solution to the detonation problem which everyone runs aux injection for?

Yes, on VP unleaded 103 I have seen them making that with a T78 at aroud 20-21 lbs, but regardless of getting out of a pump, I think people mean just the normal premium grade fuel 91-93 that you can get in every state, not just some gas stations that offer race gas.
I do think that AI is very realistic in a daily driven car though, it only activates at a certain boost, or dual stage on two boost levels, or computer controlled, etc...
so its not like you are spraying all the methanol or water all the time. And they have options like a bigger tank, low level and clogged jet warning light, etc...
its also great insurance if you just are spraying water on top of your regular pump tune, for a bad tank of gas or something like that.
