1G Almost ready to dyno...but got Q's on E85 and nitrous

[turboglenn]

Well as it states.. I'm about ready to go to dyno.. 'm getting all the bugs worke out, selling my 2nd (low pressure) 255 with an install for the money to cover a 2nd 255hp (if you remember the issues i had mixing them you'll know why i'm doing this) Also the 2nd pump will only come on above 20psi and when the nitrous is active.

I've only got to payfor and istall my 20g and tune it with tht and the nitrous and it's off to the dyno... After that I'm buying a new set of slicks and it's off to the 1/4 mile, all i can say is f#(k this 1/8 mile crap around here, I could almost spin the entire 1/8th on an open diff with 26'' tall slicks and only 19 psi, this year should be fun if the axles don't give out (they are new at least)

My main questions is, has anyone ran e85 with nitrous? If so how much a jump in the ful jet was required (im starting with a 35 shot and working up to a 70-75 range) I was able to get a used fogger nozzle and a fuel line from solenoid to the nozzle along with some jets today for a really good deal ( i mean really good, or it would have had to wait) All the parts are in good shape, so my n2o system is once again complete I got some various jets while there in case i needed them to fine tune or make more power, plus being that it's a NX nozzle i can use the nitrous jets on both fuel and laughing gas...IIRC NOS brand used different ones but i could be mistaken it's been several years since i ran the laughing gas on my car

Here's the list of jets i have in NX brand #18, 22, 31 and 38... Then i also have a 42 in NOS brand that with just a slight triming of the stem will work with the NX nozzle i'm sure. (plus since i learned tonight through test fitting that the jet size is just a nmeasure of the whole in thousandths of an inch i have the array of bits to make any jet i want...just about anyway)

NOw the NX site says 31n/18f = 35hp shot... then 41N/24F = a 74 shot.the NX site says the fuel jets are based on a static FP of 43 psi will this make the same jet stay right as the FP rides???? I can get more jets, but i figure these will kep me in the lower limits until i figure out how my combo will behave. I was to start some where between the 35 and 50 areas... So using their nitrous jet recomendations is there a "rule of thumb" on how far to increase the fuel one when on E85 ?(and i mean besides the general e85 rule of ~30% more)

Dyno vid to come soon, then as soon as i re-save after the new turbo for some new slicks there will be 1/4 mile footage to follow hopefully you can see me get asked to stop racing because i dont have a cage when i (hopefully) hit high to mid 11's the first time. With all the new stuff rangine from cams and springs, to a 9:1 motor with H beam rods, no B-shafts and an 8lb flywheel and better driving skills on this car over the last 5 years i better be well into the 11's.. I think the smooth shifting TRE stage 2.5 + quiafe LSD is going to make the biggest difference though, and with the addition of N2o during spool and in the top of third there should be plenty of room to blow the launch and still hit 11 something I want to sand bag untili get a real good 60 foot time then afte the launch have a higher boost setting and ride the nitrous as lons as theirs traction...... I will shat my pants and admit it if the car were to some how go 10's ( I used my coil over suspension and a set of 4 SCCA style scales to balance the weight on the front end and bias as much of it to the front as the suspension would allow with out looking plain retarted/wannabe rednek cmaro )

According to my old logs the shifts are the only thing tht kep me from an 11.99.. i could count around a second or more easily in shift times alone on my datalogs with the stock trans trying to keep me out of any gear i tried to grab, this TRE is like butter at 8k RPM and me likey!

Ideas on the jetting is needed.. all other coments welcome ( as long as tehy follow forum guigelines anyway )

Which dyno are you doing to?? Hey, whats up?

 

[gsxtasy]

I looked around for awhile on this question Glenn, and this is what I came up with. Seems pretty helpful though...

AARon...Great link thatnks! When are we tuning that AEM or did it get done all the way yet?

As for where to dyno.....MAybe subime again if i can get a SOLID verbal agreemnt worked to where if i can't make boost i don't have to pay for any more than one hour. When i called around and explained why i was looking for a new place ( i didn't mention sublime's name becaus they've never done me wrong) but the other guys said even if i'm there a few hours, if i can't make the same boost i make on the street they will only charge the first hour at a 2nd hour rate to show that they do care about my results, i told them what i spent (which was fair, ill admit that) but there was a LOT of hours on that dyno and to not make full boost just ruined my month, especially when i left and went right past 25psi and when i was on the rollers couldn't hold a steady 21, it was always setttling to 20... once it spiked 23 and fell right away.

I guess he kinda got offended that i posted that i couldn't make full boost there, but i've never had an issue any timebfore...and that was on EJ's dyno which now belongs to corvette specialties... I wish i coud find out who has the in ground one where PArish dynod his vehicles, ihead that guy is CHEAP on prices as long as you try and send other peple his way opr if you have any issue while there

If i was financially loaded like i was last summer when this happened it wouldn't bother me as much... and it really didn't too much because i was happy with the numbers at the boost i did hit and for no more timing that i was able to pull (it was a pump gas tune)...and like i said..Mike's alwasy been good to me, helpfull and honest..he said he didn't know why it did it butcouldn't think of how to solve it either but hinted to the car for a fault..butif i can make 30 on the street i can't see how it's the car

So i think this time i will completely road tune (even if i wear out a set of porterfields, boil my fluid and warp my already warped rotors some more, but covering thie whole families bills on my budget being self employed in this time of financial crisis, 'im scared to take a chance of spending 3-400 bucks for a patila load result... i want braggin rights on paper... some others have told me they go to fast by KC for this very reason, but that's hours away

I got it!!!!!!!!!!!! ANTI LAG ON THE DYNO LO ... i can make full boost in neutral with that , but i don't think i'd get a true reading on the dyno... but being that he's ablock away from me and as statedalways treates me good on parts, i feel i owe it to give it another go if we can come to anagreement...maybe take him fo a ride first, then get on the dyno and if it aint hitting 30 psi, justc all it quits after the first pull..i dont know i'm stumped and have a verry small budget aside for dyno time after my new turbo and nitrous install...damnit i want ot break the 500 mark BAD!!!

sublime is fine. I usually go to dynosport in lincoln, its a dynojet so numbers are more comparable to others but either is fine.
Also what gear are you dynoing in?

 

[Ajax]

Glenn you could always come up to Sioux Falls we even have a inground AWD dyno. And then help me do a rebuilt again while you are here!

The rest of my turbo setup should be coming this week, hopefully. Then I'll get a hold of you to do some welding on the stuff we talked about. Then we can check out the tune, and make it balls to the wall, this thing should fly.

We'll have to run em come spring Glenn

Even though you already bought another 255LPH pump have you ever thought about switching to a manual pump. Magnus makes a bracket that connects an Aeromotive manual pump to the intake camshaft. I made a similar bracket for a H22 Prelude that was switching to E85, and an A1000 pump could barley supply enough fuel. I made a few runs at Sublime and had the same problem only my car would barley make 23 PSI, I was tuned for near 30 at the track, the car was also stripped and we had to tighten the tie down strappes like six times because it was wondering around on the dyno. I was kind of pissed off, I did not even keep my print out.

 

[turboglenn]

squeek.. You're on.. I'll get smoked but i'll run ya anyway

spoonman... he acted like that was unheard of and had to be my car's fault, but i told him, when i left i hit the street and was making 25 - 27 psi everytime i floored it and the best we could do there was spike 21-21'ish then settle to a solid 20.

I've got the duals back in action, but now have to learn the behaviour of them, tune them and hope that i can get away with higher fuyel pressures to use less pulse on my tune... becuase something is running out, either pump or injectors and unless it's a clogged filter (cleaning tomorrow) i'm going to be stumped as to why i have had to add so much pulse to things to keep up with target AFR's

Does anybody else have any good links or info with nitrous and e85? Preferably NOS
