I need to make as much power as possible, because I need to beat a 2013 BMW m6 Convertible.... I have a 2005 evo 8 with a fuel pump, 3 port, exhaust, intake, and a RRE tune making 295 AWHP. I have $2,200 to put in the car, I was thinking of doing cams, injectors, and a duel map for E85.I just replaced the clutch BTW. Is it possible to beat the M6, that car weighs at least 1,000 pounds more than me, what do you think?? Also what horsepower do you guys think I will make with cams and E85?

 

Will not give any power but for about $25 you can get a fuel pump rewire kit from STM. Which will maximize your current fuel pumps capabilities. Which results in more power.

 

If I were to guess you're going to need another 100whp at least to be able to keep up with him. My vote would be bigger turbo, injectors and tune. Look into the MAPerformance stock frame turbos extremely good bang for buck.

 

BMW runs a 12.4 1/4 mile. I would suggest a bigger turbo FP green or MAPerformance turbo, E85, injectors, cams, and a good tune. Should be close to your budget as well. Remember though, you can have all that power but you still have to be able to put it down. Why do you need to beat this M6?

 

if you plan on upgrading the injectors and the turbo dont forget the fuel pump... you will need at least a modded 355... but i recommend a 450 because it wont stop here...

then a mild set of cams maybe gsc 272s or kelfords.... a map ef2.5 and 12-1500cc injectors... then call up aaron at english racing or tom a tsccomp and get a flash... actually i'm over you budget by a good bit... but thats why they say if you have 1800 budget for 1500 right...

 

most of this you could pick up used and save some bucks... but never trust a used fuel pump... and nobody will be selling a 2/2.5 just yet... unless something aint right ya know

 

I don't want to be the bearer of bad news, but he is pushing nearly double your horse right now. I wouldn't rush to "beat" him in a race. That is how you end up breaking.

2013 M6 = 560hp (at the crank) BUT weighs 4500 lbs.
Your evo = 295hp (at the wheels) BUT weighs 3000 lbs.

This isn't a muscle car where you can just throw some random big cam on it and add more fuel and make gobs of hp. You need to think out your mods.

You have: 295hp
Fuel pump (Guessing 255)
intake
exhaust
tuning equipment
new clutch (STOCK?)

You need: ~450hp
Bigger injectors (1150cc at least if you plan to run E85)
Bigger fuel pump (400 or 450 if you plan to run E85)
Intercooler piping to replace that mesh junk
Bigger turbo (I love holset)
Manual boost controler
Gauges to monitor what your car is doing
Cams to match the turbo you choose
Probably upgrade your clutch if it's stock
Tuning Tuning Tuning.... It's the most important part.

Personally I don't think it can be done with $2,200 but please keep us posted as this would be a pretty solid budget build.

 

a friends m6... he was talking trash and i dont want to lose haha

 

i just got the ACT street clutch with 1,000 miles on it... probably going to try out the cams, injectors and E85 and see how it goes. also some suggested a fuel pump, i have the walbro 255. All of this work will be done a Road Race

 

pick up an evo 9 turbo
1000+cc injectors
walboro 255 (you can't run e85 without it)
and RRE's e85/91 dual map tune.

I have many friends with evo 8s with 9 turbos stock fmic stock cams making over 400whp on RRE's dynapack. With 400whp and a good launch you should see mid to high 11s!

 

If I had to beat a new M6 on a $2, 200 budget, I would buy either a used Black, or EF4 (used), and also a used 3.8" core IC. Maybe a single punched Walbro and 1400-1600cc nozzles will provide sufficient fuel. On E-85 and 32-35# you should be able to walk away from him from an 80 mph roll-on up to about 125 mph. Be sure to go for pink slips. If you don't beat him then douse your Evo in gasoline and throw a lit match at it.LOL

 

Jimmer good work up front..

Always funny to listen to bench racing... , you need to normalize the analisys. If he has 560 hp at the crank, lets use 15% reduction to the wheels, as thats what most use for the evo , so that gives him roughly 476 at the wheels vs 295. So now look at weight, 4500/476= 9.45hp/lbs for the bmw. So you need roughly 350hp, or basically 3200/350= 9.14 hp/lbs.
Thats all other things held constant-- and its a rough guess but a lot closer to reality-- no offense anyone. Now that brings things into perspective and your 2k will get you what you want. Be it cams, turbo, what ever your going to need at least 55 more wheel hp then you have today to even come close. Surely 2k will buy you that. GL.

 

That's pretty impressive with just a IX turbo. But it goes to show, the tune is everything. It's like the old 14b guys on 2G DSM's running 11's-12's on a turbo that can flow minimal airflow. It's all about supporting mods and a tune.

Thanks, I guess I just didn't realize how quick Evo's got for so cheap.



OP please keep us up to date on what you end up doing and how this race ends up.

 

Cams, injectors, Map ef2, and race from a stop...

 

Cams $522.75
Valve train $200-$300
Walbro I'll say STM 450 $220
Injectors for e85 the smallest 1200cc $405
You can find a good black or ef4 for a good price maybe $1800 for a black
That's not adding labor if you do it yourself
Tune I don't know if you are on sd so anywhere from $200-$350 with Tom TSCOMPUSA
