HUGE A$$ FLAMES on Start Up !?!?
Hi all,
I've got a question. I am presently breaking in a new motor and something kinda freaky happens and I am not sure if it's normal.
My car is a Jspec RHD R1 with a larger than normal streetport. I've got about 620 miles on the engine so far and I recently installed an off road catback and mid pipe ( 3.75" ID pipe). I get a little trouble when first starting it. It will catch and die unless I give it a little gas but not a constant feed.. I kinda' have to blip (3 or 4 times) the throttle a bit until it catches itself then it will idle ok. Once it warms up its fine. I can start it normally. New plugs in there as well.
When I blip the throttle.. and I mean if I rev it to 2000 -3000 rpm I get these HUGE *** FLAMES shooting out the exhaust until I let her settle and idle.. once warm it won't shoot flames if I rev it like before.
The engine has been modified to flow more oil other wise I normally wouldn't rev it past 1500 RPM on start up. The oil pressure at idle is 55-60 psi and increases with throttle to a max of 100-105 psi. The rest of the engine does not see this oil pressure..just everythig that is fed fromt he oil pick up in the sump.
Please post your opinions.
Thanks a mil,

I was wondering, is the oil pressure your getting from the stock gauge/sender unit or did you install a new oil gauge. Also, what ECU are you running and do you happen to know how big your injectors are?
on a side note (which has nothing to do with your question), do you have trouble with boost spikes?
P.S. Flames won't hurt your car (unless they actually burn your bumper). The worst they could do to your engine is to foul your plugs a little faster and rob you of a little power (I'd rather run rich then lean).

MIne does the very same thing! Well, minus the 'huge' flames, I get little flamepuffs. But my car will die as well, like it doesn't even try to idle, it just revs up then right back down and shuts off...so i have to hold the throttle down for a sec, then everything is fine.
I don't have a streetport or anything like that yet, just all the bolt-on's, but I didn't have this happen until I got my PowerFC, i guess it's just the way it's tuned?

No .. I am running both the stock oil pressure sender and gauge as well as an aftermarket one . I ran one line from the housing and T'd into it with two lines, senders and gauges.

Still breaking in the motor with ZERO boost at the moment so I can't say if it will spike.. but it should not..as the stock DP is still on the car.

Flames are cool. 
Do you have a aftermarket computer? If so which one? Did U upgrade your injectors? Has your car been tuned? Sounds like you are just runnin rich.

do you have a turbo times? if not,im not exactly a rotary guru, but since your having trouble at start up, could it be that the engine is slightly flooded from the last time u turned the car off, which would also cause flames? all i can think of besides running rich from the start.

I put on my Nights Sport ECU whichis tuner for intake, exhaust ...kinda' like the 300 buck ECU Pittit sells.. and it seems to run much better now. I think it was a little too rich on the OE computer.
Will post as things develop.
