The Reno thread in which no arguing will take place....

[pnklmnd]

i need to get a tach too...mine doesnt work all my other gauges work(except oil pressure)...i have no idea what rpm i am shifting at...its not like it matters as my car sputters (not rev limiter(well at least i dont think so)it feels different...my afc is afc1 so it doesnt give me the digi reradout on rpm the lights change but i really have a hard time believing the lights(need something more reliable)

Does Reno have any fast DSM's yet? I see 800 of these cars when I drive around every day, do any of them run worth a $hit?

No.

 

[peregrine]

how?

enlighten me! i have taken off my exhaust and my boost hits 7psi then climbs to over 15 towards the end of the gear...that i am not liking i dont want to turn it up...the intitial boost is low the peak is what i want but with my estimate of what my boost will be in the end it seems unsafe...
if im at 7 then spike to 15 that is 8 psi gain i want 15 psi all the time so that would be 23ish psi! that seems a wee bit high to me...

read. alot.

 

[pnklmnd]

i gonna be getting a front mount here soon...my intercooler gets heatsoaked pretty bad after one run...

even in the freezing wheather here!

no we all know that spoolns is the only FAST one around! and it runs soooooo good!

Hahahahah... there's gotta be a couple quick ones around town somewhere.

 

[pnklmnd]

hahaha yeah sean obriens(john's old car)...
jarel is quik...

ummmmm that about sums it up i believe...there is a few other firstt gens runnin around...the other white with fmic...and that red laser is quik i think?

A first gen on a stock turbo will NEVER hit fuel cut at this altitude. A 16g car wont hit fuel cut with a modded mas OR an AFC (or both, which is better). Anything over 13psi on a stock intercooler on the 14b will induce knock. Dont do it. Anything over 14 to 15psi on a 16g with a stock mas (even a modded one with the honeycomb removed) will drop counts through the MAS, inducing knock. Dont do it. Gutting the first gen MAS enough to not drop counts on the 16g requires removing the WHOLE lower section, and enlarging the opening. At this point, the car will idle rough, and will want to die when the fans kick on, but it'll run on 21psi with race gas, and be in the 12's with a good shifting trans. 19psi on the stock turbo through the stock MAS (with race gas) will net LOW 13's up here (try 13.1 a la John Hill). We went 13.4 @99 with only a fuel pump, boost controller, K&N and race gas. That was in Fallon folks. Make sure your timing is dead on, the plugs are at least one heat range colder, and gapped at .028. Run no less than 110 octane. And if the clutch is stock, rev it to 5500, and dump it. If its not stock, rev it to 5500, and slip it just till you feel the car lift up, then dump it too.

i actually hit fuel cut with the 14b up here. but it was at 20 psi on race gas :laugh: i wrote a thread awhile back on how to do it john. i just remembered it. http://www.dsmtuners.com/forums/showthread.php?t=60008

 

[pnklmnd]

thanks for the info john and josh...

my mods are as follows
k&n air filter(no can)
bcs bypass
exhaust is off after my o2 housing
taylor wires
ngk plugs(not sure the temp)
afc 1
dsm diet plan(stripped rear half, working on getting all the sound deadening out, plan on taking the rear bumper support out as well)
my mas screw is backed out flush

i am not positive it is fuel cut, and by the way you guys are talkin it cant be?

my tachometer isnt working so i dont know at what rpm it starts but at first i get .6bar of boost then part way through the gear it continues to climb to just over 1.1 bar...at this time i hear popping from my exhaust? i get light popping in second and 3rd towards the mid to end of the gear. not as noticable as first gear tho...my intercooler gets heatsoaked really quik...i want to get a fmic and plan on it as soon as i have time/money to weld my hardpipes...im thinking of going with a 8-12" x 24 x 3...this should be able to suppoprt my needs down the road turbo wise...

any ideas on why my car starts popping out top of the gear?

im thinking i need a new alternator as my lights flicker at idle and my car sometimes can barely idle...and when i hold the gas to keep it going i get a surge roughly every 2 seconds...wierd?

Hey John...or Josh, How much boost can a t25 handle before hitting fuel cut? I think that's what is happening to my car because I am boosting way higher than stock. But I'm not sure what else it could be.

 

[peregrine]

what is your car doing?

 

[evilfwd]

If I go full throttle from about 2500-3000 rpm in third gear, I get a ton of boost and hit what I think is fuel cut before I get really high into the gear. It doesn't happen in first or second gear, and not if I'm racing. But I won't race on the highway because I'm afraid I'll boost too much boost, and then fuel cut. If that's my problem.... when it happens, I'll be floorin it, and then the engine just stops momentarily, then i'll let off the gas. ???

 

[pnklmnd]

you wanna race tonight?
the supra is haulin ass!

Dont do this. Put the damn downpipe back on. Your just killing the turbo by allowing cold air to rush into it when you shut it off.

If you have a 14b then LEAVE YOUR MAS ALONE. Only remove the screen or back out the screw if you are gonna run it on race gas. They run lean enough for our crappy 91 octane. Like I said. 13 to 14psi is all it can handle on pump gas.

I bet you are having an ignition failure somewhere. Be it old and improperly gapped plugs, or failing wires. Once the car starts to get loaded in the high rpm range, the ignition is misfiring.

im thinking i need a new alternator as my lights flicker at idle and my car sometimes can barely idle...and when i hold the gas to keep it going i get a surge roughly every 2 seconds...wierd?

You need to check for vacuum leaks, set the base timing, set the idle speed correctly (with the BIS), have properly gapped plugs and a good set of wires first. It sounds like your car is in poor running condition. No offense, Im just trying to help.

You wont fuel cut on a T25. You can remove the wastegate line and pressure spike the turbo and it will still lose boost after 6000 rpm. The turbo is just too small. Read my post above about a car that pops or sputters under boost.

 

[peregrine]

god dammitt! i just started to type a long post saying basically the same thing when i saw joshs post. oh well i cant say it any better. :laugh:

 

[evilfwd]

I know the t25 is a small turbo, but it doesn't feel like I'm just losing boost, it feels like the entire engine stops suddenly. It's only happened to me twice, once in Cali, and once here. I'm too scared to test my car to see if it'll happen again cause there's no way that can be healthy for my engine. What do think it could be?

my car came with the mas screw backed out...i need to get a new mas anyways...i rarely drive the car...

you think that really affects the turbo that much? so you think run a stock dp? and it would get the same performance?what is it gonna do to the turbo?

i have new plugs and wires all gapped at .028...im thinking it may be my pack tho...

it runs fine most of the time...i think i need a new pack...as the idle just drops really low and bounes sometimes? not all the time at all...and when i hold the gas pedal down a lil to keep the revs up it does lil surges...

john heard my car idle and says it sounds fine?

no offense taken at all...i know you no more then me thats why i ask!

 

[pnklmnd]

hey josh or john would it be better on my turbo to run a sort(10-14") piece of pipe from my turbo underneath my car? so "cold" air doesnt go into my turbo?

 

[evilfwd]

John john.... what's up dude? So at least I only took the supra by like, a car, last night instead of two or three cars like tuesady. You could definately feel more power in it for sure. If you had traction it would be a different story.

hahaha i know it didnt get traction til 3rd about...it was a launch from 3000 too...not a high rev launch at all but they just spun not as bad as when i raced you...the tires were cold when i raced you the other night and if they arent hot then they dont hook til 3rd...that launch i was thinking my tires were warm still...so my 4500 launch was pointless i stayed in the same spot til 3rd ! it has to much low end juice for that cars own good!

the tires are 100% slicks now! they are soooo bald and when we went to do donuts they got so hot that there is rocks imbedded in them and ya could mold them after i was done!

we reaked havoc on my moms neighborhood lastnight too sliding around corners all over the place...oh well that neighnorhood has gotten used to that car!

 

[pnklmnd]

hey john....

you wouldnt happen to have a tach just chillin around? like not a stock one but a smaller one...i cant set my idle if i dont know what it is!

im thinkin of just going and buying a cheap one of some sort that i can stuff into my cluster and cover my stock one! no big shiftlights!!!

 

[evilfwd]

Hey we should just reconnect yuor exhaust at the o2 housing, and disconnect it right before the cat. That way, back pressure is still pretty much eliminated and you dont have to worry about messing up the turbo. It shouldn't effect that hp that much either. I mean, it's still gonna pull hard thrugh every gear.... Are we gonna do your cv joints after christmas?

 

[pnklmnd]

i may try and get another flange for o2 to dp and weld a medrel bend onto it that will drop it under my car...it'll be 3 inch and i wont have to worry about it...and depending on cost of that i may just do the whole exhaust...i just need to get time in at the welder...

cv joints yeah im planning on getting mine ordered soon...i think im getting a timing light and compression tester for christmas...im not sure...im gonna go get all my tools from panther valley soon...i swear that if there are ones missing im gonna have another talon!
