Blevins Tuned Evo 8 Stock Turbo e85 Part 2!
 

Hey guys me and Adam (colt4g63 on the forum) finished up the email tune on my car late last night and we got some great results. First off we did a tune back in early January and the car made 415/420 Dynojet VDR which was backed up with a 121 mph 1/4 pass.

Since that tune the only thing i added was the MAPerformance O2 Dump. It changed the afr's in spots and alieviated some back pressure I'm sure. So I called up Adam and we started tuning the car. The car is on e85 and spiking boost at 30 psi.

Here are the final results. Keep in mind the 415/420 pull was in JANUARY lol and its august now so I'm sure it would make more power in a january vs. january pull which makes the gains even more impressive. Still stock 10.5 8 turbo.

Just to take the road for the VD out of the question this pull and the previous pull at 415/420 was on the exact same bridge in the same direction to take road slope out of the question. The car feels very smooth and i can't wait to get back out to the strip in this bad boy!

I didn't even hear about Adam through Evom. I had heard about him through the grapevine from a few locals and the mitsu community. I contacted him after seeing sub par results from a prior tuning experience and we went from there. Mods feel free to check my pms to see we've never even made contact on this site lol

what dyno correction factor you use with the log ??

very impressive numbers for this turbo !!!

damm this is alot of power for the stocker 8, is it wise to get this turbo than the 9 then? anyone? since i have a evo8 with the 9.8 hotside thanks.

no because a evo 8 turbo is smaller then a 9.. so if the OP installs a 9 turbo he will probably go 122-123mph in 1/4 vs his 121 now..

his setup just works well together. 9 turbo will always be bigger then an 8.. nothing will change that.

strong car svt_lightning!

EDIT: if you already have a 10.5 housing evo 8 turbo its not wise to get a evo 9 turbo because the gains are not worth it for the hastle and price difference.

Always a pleasure tuning your car Jordan/ svt_lighting01 {thumbup}

great results! glad to see you back up your vdr claims!

doesnt the compressor wheel determine size of turbo? 8 and 9 turbos have same compressor wheel.

enough results with stock 8 turbos on E85 have been posted to make it clear the larger compressor cover of evo 9 turbo has no advantage of smaller 8 cover. all the larger compressor cover does is slow the air down so when the air hits outer wall it creates tad less heat. worth a few hp on pump gas . but e85 and good intercooler doesnt care about the extra heat. it just creates power with it.

so good advice to give is if you want to make e85 power on stock turbo dont waste your money investing in the 9 turbo. both turbos make about 420whp on e85.

Yes both 8-9 turbos have the same wheels. Its the larger exhaust housing that gets you the most gain out of the 9 turbo over the smaller 03-04 8 turbo. {thumbup}

Thanks for the comments guys I hope to get the car back to the track. Like I said the 121 trap wasnt this tune that was granny shifting and 10whp less which is a little more when u factor in an August tune versus a January tune. I'm hoping for some 122+ passes for sure when it cools up and a good track night comes my way!

I'm hoping to dump this 8 turbo next summer for some Adam tuned fp black action!

Just go T3.

Factor in selling your stock frame stuff and that'll make up for the 02 housing and modifying the LICP.

its been dyno tested before. there were gains of 10-20whp. so its not worth unbolting another turbo just to pickup 10-20 when you can spend the money on other things that have better bang for your buck + much easier installation process.

updated my original post also.. i agree its not worth it.

I would rather stay stock frame to keep it covert for street purposes lol. Sneak attack. And I agree the 9 turbo is not worth the effort and $$ IMHO

im thinkin about switchin to a different dv(stock style) do u think it would b better to save money and crush my 9 dv or get sumthin like the forge rs(they r rather pricey)

I think some people have issues above 27-28 psi with the stock 9 it just depends what ur plans are. I've modded so when I go turbo I don't need any other mods But it's up to you at the end of the day.

yea im kind of in the same boat u r, tscomp is tuning me rite now on e85 with just as much boost as u, so im wonderin if i can make close to the same power u r with this bov or is it gonna hinder my power even if it is crushed? the only mod u have different then me is cams

It's really hard to tell man every car is different. I think most cars make about 400 flat or a little more typically like this type of set up. It all about how good of shape the motor is in, boost leaks, etc etc. good luck with your tune man. I went with forge because I know I'll be going aftermarket sometime and figured why spend money on the same mod twice. Mine holds about 24 psi at redline with this set up.

But if you have stock cams I think it will be a task to make 410+ on 8 cams but I'm sure it's been done.

well turns out the effin dv was turned around(wrng way) it was like taht since i bought the car used from dealership, which makes me think y i had to replace the stock turbo, that went out like a month ago lol neways, i went outside quick and switched it around, def doesnt hit as hard, but before i switched it around it would hold 24psi to 7500k, now it holds 22-23 to redline. so does this sound about rite to u SVT, also if i can make 400whp/400wtq, i will b perfectly happy

o and it use to spike over 30, now with the DV the correct way it only spikes to around 27-28. this all sound about rite?

That boost spike would be controlled by your boost control. You may need to turn it up if the tune calls for that

do u remember wat ur spike was off hand? like from ur graph u posted? im thinkin i should spike between 30-32 psi then fall obv

Spiked about 29 and held 24 to redline on that pull. On a cool night it usually sikes 30-31 And holds 25-26

so ur thinkin i should make 400/400 atleast? obv a guesstimate. real quick heres my mods, megan tbe, Map licp, agp 3.5 ic, fic bluemax 1250cc, act stage 2 clutch, evo 9 dv(soon to b crushed) k@n cone filter, grimmspeed 3 port...i think thats it

o and 10.5 8 turbo

Without cams or a bigger intake pipe I doubt it will see 400/400 but I could be wrong. Ive seen hem make 370 before its just all In the car. But with 8 cams and the stock intake pipe I would say it would be a stretch. Not so much the pipe but it def helps. Especially in late summer heat it will be tough. But I hope it does!!

the only reason i havent changed the intake pipe is ive heard unless ur running big turbo it doesnt make that much of a difference...this is wat ive 'heard' tho

I made 360whp on a tune by a previous tuner last year. And all I did was adjust cam gears and put a Perrin intake on the car and of course let Blevins get ahold of it, and bam! 415whp. I'm sure you gain more off an intake with a larger turbo but there are gains to be made with a stock 8 at 30 psi as well

i think if i make 380-390, ill b happy, regardless, i plan on going big turbo in the next couple yrs, so im not to concerned, but i have faith in tscomp so im sure i wont b disappointed lol

Let me know how it turns out.

i will man, ive been tuning with Tom for quite sum time now, everytime we think the car is good to go stupid sh** has come up like boost control, or leaks, but now that everything is good to go, im hopin to atleast get this e85 tune done soon, cuz we havent even started pump gas yet lol plus hes gotten really busy over the past couple months so i think i gotta wait longer lol

I gave up on pump after feeling e85 lol. I used another tuner when I first got my car and the power wasn't that great for two tunes and I thought it was the car but as soon as I jumped ship Adam really hooked me up with Hp! Turned out the car was great. Couldn't be happier

imma send u a pm lol

Ok lol

Nice numbers! Looking at your mod list, are you running the stock valvetrain or upgraded valvesprings for the HKS 280's?

I bought the car with the hks 280's with upgraded springs and head studs. :)

Also tuned by Blevins. He did a great job. Going back soon for dyno tune in a couple of weeks when I drop in hks280"a and a few other little things. Why gains did you get off 02 dump?

I like stock turbos. fun for a street car.

Yes they are!

very nice

Thank u sir
