Yes thats correct the built motor car.. We have made 420 on stock motor no cams.. Still 93 pump.. Car is running like a champ..

I cant wait to get his car on our local dynojet and see is all the rumors are true about the Florida Dynos reading higher the the rest of the world. We shall post results

and im sure you could easily see 420whp on pump, but i am by no means a pro tuner, and this is all me tunning.

 

If it reads higher by a significant amount ill paypal you 500.00..

Our cars with less than 800hp on our dyno run 8s.. 460hp ran 10.6 in a full street car.. and my evo X with 350hp ran 11.8.. so Have at it bro.. Dyno it for me please..

Matter of fact ours reads very close to Sean Iveys Dynojet in NJ also..

It would seem that you are playing an expensive, potentially crippling game of Russian Roulette being this is your only means of transportation. I think the unavailability of E85 is perhaps among the least of your concerns.


One local hot rodder went so far as to get a replacement "Flex Fuel" emblem from a Chevy dealer and stick it on the back of his car. That shut them up.

But seriously, over here, the only cars I see filling with E85 definitely aren't flex fuel GM grocery getters!

 

hey guys, i'm pretty much brand new to the forum. a few of my friends are long time members so here i am. anyway, i got the aem meth set up which seems to be working great so far. has anyone had any problems with their o2 sensors going out after installng their meth kit? i went from like 20mpg to like 11mpg. any thoughts...?

 

Methanol does not adversely affect O2 sensors. If you are getting 11 mpg in average driving, you definitely have a situation on hand.

 

Yea if anything you should have better MPG

 

i would not say that, the car is still using teh same amount of fuel under daily driving because meth is now always flowing. and with the new found HP he may be driving more aggressive simply because it more fun... resulting in ****ty gas mileage. LOL

 

First part is true but when under boost the meth is a secondary fuel which should lower the amount of pump fuel used. Im getting about 19-20MPG and Im in boost a lot more now with my power levels. Even use the A/C sometimes. This is suburban driving

 

I agree meth injection is very risky. I dont doubt for an instant that AWD has seen more blown motors from meth than any other fuel. But blaming it on poor distribution per cylinder is 100% incorrect diagnosis.

looking at blown 4g63s for years. if engine doesnt have meth no 2 will blow first. followed by no 4. no1 will be least likely to blow. Its because air doesnt distrubute equally due to intake manifold design. Then when you run meth the air is now filled with meth so order of cylinder mixture reverses in order.

lean to rich=
no meth 2, 4, 3, 1
with meth 1, 3, 4, 2

DSM link for early 4g63 cars has a nice feature where you can watch knock noise of all four cylinders. The noise tables 100% confirms this.

People who run meth are budget minded builders. so the tune gets short changed. if system is reliable and tune is spot on 93/meth motors perform as well as any other.

 

I disagree.. The same has been seen for years with Nitrous Wet kits..

Explain why 1 CYL ONLY.. The car ran for a long time to have the carbon build up on the cracked piston so if they blow in order what is it like 1 year in between each failing?? Why are the other 4 not melted AT ALL, not cracked and in good shape..

I also disagee that 93 Meth motors perform as well as any other.. Waiting to see 93/meth cars run 8s like E85.. And will be waiting along time to ever see that..

I am also curious how you can attribute this to intake manifold design when you dont know what intake manifold was even on the car.. it also goes against what dave buschur found on the flow bench during intake manifold testing..

Mike

 

nitrous wet kit would be same as no meth car. nitrous is adding a ton of oxygen and a little extra fuel.

lean to rich 2 4 3 1 remains as no meth car

I have seen far more blown motors than you. and i have used 93/meth succesfully for 50,000 miles on my cars over the years.

Never said 93/alky will make same power as e85. stock engines run/perform well. runs/peforms well is key.

 

Your opinion and my opinion are different.. well leave it at that..

Mike

 

pics of other pistons?

Also I believe lack of a purge button/ switch is crucial in proper operation of meth.

 

I will leave it at your opinion and my knowledge are different
