Cyclone record dyno!

[keltalon]

As a man, who has not had the pleasure of driving the DSM he has been building for about four years now: I am impressed. Based on your threads, and videos it would appear that you have not given up and have maintained focus during your build. I dont care if your intake is made of cardboard or space metal, your numbers are impressive. On a side note, people on this forum are very technical and skeptical so that being said their going to dissect every thing you say; one to authenticate your claims, and secondly out of the unwillingness to acknowledge resentment envy or whatever other words their willing to deny ....because at least half of us on this forums daily drive some other car Not our dsm.
But for the rest of us, who get exited to see others do well i applaud you .

Yeah this is true but sometimes this technicality obscure them from innovation. Remember I am a craftsman by trade not a mechanic or technician I just share results good or bad Thanks for your honest observations you certainly speak with a dept of wisdom

Your pump maxed there? I'm soon to be going to e85. Have any experience with a rewired 255? I'm sure it's my weakest link. Through link I've got to 44lbs a min but that's on pump and starting to spin in third at 20-22psi. Waiting on my new clutch to come in and then I'm thinking a dyno tune on pump & e85. Just curious if you maxed a 255 out or not and what you would recommend for pump or pumps upgrade?

Thanks for being a complete douche to me when I made it clear I wasn't trolling you. Like the guy that replied after me said, I was interested in your work.



Have a good day man. Life is going to suck if you believe everyone that asks questions is out to get you. I'm a cyclone fanatic, and have been since the days where guys were throwing them away and saying they were useless. Back before DSMLink V1 was out and people used SAFCs as the go-to solution, so I was genuinely interested if you had modified it at all.


@ Rats.

I maxed my rewired 255 on e-85 at around 530ish whp on a fwd dyno jet. Airflow reading were in the neighborhood of 49lbs of air/min. Go here in post 119
where you can see that fuel was starting to suffer around 6600rpm and at post 131 gave completely out of fuel.

What feed size you using Kel? stock, 6 or 8?

 

[1G Eclipse94928]

Now you just need some stickier tires.

Are you running a wally 450 e85 pump? Just curious which pump your running and where u run out of fuel pump at... I am running a rewired wally 450 and hope it can take me to 700awhp with my FIC 2150's before having to add a second pump.


Awesome numbers by the way!

I was interested in details and results. I have a cyclone powered vr4 and was curious as to what you were innovating. It's ok I will just figure it out myself. I thought this was going to be helpful but instead you want to make this about you. Good day.

I am still on the stock lines it was brought to my attention yesterday that this is my be my issue not the pump and that I should upgrade the lines first. I will heed the advise. I will be reading a lot this weekend to see exactly what size lines others are using with similar power.

I am running a rewired walbro 450 and its running out according to dsmlink at or around 6500@34psi. I did knotice that when I changed the exhaust manifold to the tubular from the log erl the car exhaust note changed and there was a big improvement in power in the upper rpm range. Here is what's more interesting I had to rewrite my tune to compensate for the change. I had to up the ve table all across the board and rightly so to give the car the fuel it needed for the better flowing exhaust manifold. My egts also dropped from what I was seeing with the erl. On a wot pull on the expressway the erl would easily see 1650 very quickly which forced me to let out of the car to keep from damaging my engine.

Now with the tubular I see maxed egts around 1450. on that 665 pull the car jerked twice from a misfire which I believe to be from being lean that is why the graph looks funny. 700 I think is possible and I will make the changed and attempt again in a couple weeks before switching over to the jmf street to see how it compare to the modified cyclone.

No problem. I am here to help but its hard sometimes for me to determine genuine questions from the the rats. send me a pm what whatever you would like to know and I will do my best to tell you what I did because my cyclone is indeed not your norm I put a lot of work into it.

Yeah she eats them up.

No one is pioneering anything after 24 years of these cars being built and raced. Not a whole lot of shock and awe coming from the DSM world anymore.

Well 24 years put us at an advantage because most of us can study the 24 years of modding the cars an see what issues have been encountered by majority of dsmers and do things a little different , with much though process that it, so as to avoid the same pitfall of 24 year. I have had my share of breakage myself over the last 12 years fooling with these cars.

One issue that I experience more that once was a failed oil pump and tried every suggestion on the forums from get an oem, use straight cut gear, use helical gears, remove balance shafts you name it but as a craftsman I had one of my Eureka moments and decided to try this simple little mod on the gears and wow I have never had another oil pump issue. Innovation! here's a pic of what the gears look like after my process which I have not see or heard done by anyone. I have since eliminated the small stubby shaft and now run my own turn race shaft works flawless.

Well here is something I will share with you. Along with porting the heck out of the manifold I modified it to fit an s90 throttle body This also is not heard of on the boards because at first glance it seems that it will not work, its close but it works here are some pics of what I did.

Here is something else I did that others thought was crazy but not me. After running ross pistons in two engines , after teardown I noticed something about both engines that I didn't like. there were vertical lines in the cylinder bore these vertical lines are the main cause of dsm blow by. I started a google search and looked at a lot of dsm images of cylinder bores and found that these vertical lines seem to be the norm. This still didn't make them acceptable to me. I set on a quest to find the cause and to fix. The reason is that these lines or grooves become an escape route of compressed air. therefore I decided to switch piston brand read and felt that cp was the best to use.

So I went with a set of their stocking pistons and found a flaw http://www.dsmtuners.com/forums/cyl...89143-cp-stocking-pistons-has-major-flaw.html, in which I realized that hard way after my engine failed. When I tore the engine down I knoticed that the cylinders still looked perfect after several thousand miles not lines in the bore. Blow by was almost non existence with the cp slugs. I compared cp piston to the ross pistons and found that ross piston rings had way more tension on them that the cp piston rings. I liked that the ross pistons had nice meat around the valves and I liked the way cp rings sealed without damaged to the cylinder wall so I had a keltalon eureka moment again. I called CP and told them the issue and wanted to know if they could copy the ross piston and at the same time utilize thier rings they say not a problem just send in the ross slug and we will get it done this is what I run in my car I have no issue with blow by the cylinder seal has been rock solid to date. my current engine has a compression ratio of 9:5to1 pioneering and innovation at its finest for me that is. If anyone would lit the work order number on this I can provide it for it is stored in their data base for production if a request is made.

Ok.....whew, you had me sweatin. Im thinking 8 feed and stock or 6 return with my 450. Thanks

 

[keltalon]

I do have more to tell.

Is love to feel the torque steer in that! Congrats on getting to a HP number most only dream of! Does the s90 tb have the same bolt pattern as a 1g tb just different internal diameter?

Thanks. Yeah it's the same everything as the 1g but with 70mm opening. using with stock intake you have to leave fuel rail spacers off so the tps sensor clears fuel rail.

Here is a pull done two weeks ago boost 22 psi which is my wastegate. It was at Atlanta motor speedway this pull was to 170mph notice that the car wasn't spinning as much as when I was running 25psi in the previous video the car with little effort reached its speedo max. Egt was maxed at 1450 prepping for the 1/2 mile event in September rpm are in the safe range of 6000 to 7000 not a fan of the 10,000plus rpm 34psi should net me respectable speeds this year<

nice work on the power band. keep it up. how are transmissions holding up?

Transmission is holding up quite nicely!

 

[1G Eclipse94928]

Do you have a lsd?

 

[DSM Chase]

Kelvin something I've learned here also is people who have never broke out of the 13s will act as if they are kings and nothing you do or build whether its a 9, 10 second or a 700hp street car will match them.

 

[CrackedDSM]

Not to thread jack(thanks for the apology via PM Kel.) but DSM Chase, how are your spool up numbers with the 2.3l on the black?
