My freind wants to race me. My Blazer vs. his Passat
My Blazer is stock 4.3L 190hp at 4400rpm and the Passat is a stock 1.8 turbo with 170hp automatic
He says he will beat me. But Im not sure if I could beat a 1.8turbo.
Could I win?

In the 1/4 mile, a passat will win. You may get the jump off the line with the superior torque of the 4.3L, but he'll pass you probably before 1/2 track and leave you behind.

Here's the stats courtesy of Edmunds.com:

2002 Passat 1.8T FWD (http://www.edmunds.com/used/2002/volkswagen/passat/100003491/specs.html) - Curb Weight 3225lbs - 170hp @ 5900rpm - 166lbft @ 1950rpm - 18.97lb/hp - 8.2sec 0-60mph
1997 Blazer 4.3L 4WD (http://www.edmunds.com/used/1997/chevrolet/blazer/11161/specs.html) - Curb Weight 4050lbs - 190hp @ 4400rpm - 250lbft @ 2500rpm - 21.32lb/hp - 9.3sec 0-60mph

I had to use a 2002 Passat stats because you never specified the year, but the 2001 Passat 1.8T only had 150hp.

Thanks! He also has a 01 S-10 2.2L with 120hp
Edmunds didnt have a 0-60 time for it.
Clould he beat me in that too?

No, you should be able to beat a I4 S10.

I'll lend you my Xr-7.. It will beat the turbo passat.. dont ask how I know.. its against forum rules.

i say put some work into your blazer then race him....with a few added extras u whould be able to take a stock passat....least i think, anyone else agree?

well i ran a MKV Jetta. same car basically. only this one wasnt turbo [&:]

She had a CAI, full custom exhaust and some other ricer crap.

I just have a CAI and catbak exhaust. Ran her the whole run :D Luckily we ran out of room for the race so i won. if it woulda kept goin she woulda takin me

My blazer might take it... Its pre-vortech 160hp stock, but the stuff done to it,, according to the man who built it should be making 200-210hp.

Bored over .40/ some fancy camshaft from and I quote "from a recreational vehicle", I dont know much about that../ cylinder heads ported and polished etc, catalytic converter delete

Well, if the statistics I gave above are correct, he already has you by 1.1 seconds to 60mph... That's a tough hole to climb out of...

In order to match his power to weight ratio, you'd need to gain ~30hp just to match the 18.97lb/hp. So you'd need to be putting down 220hp atleast and that's without sacrifices in the torque curve to hurt you further. The hole shot is in your favor, but the weight of the truck is like a boat anchor. That's not even bringing the gear ratios into play, which may be in your favor in the 1/4...

I did find a *stock* time of 15.462 sec @ 90.93 mph for a 2001 VW Passat GLS 1.8T, but it states that he has a CAI and it's a manual trans car... Also... A 1998 Blazer LS with a flowmaster cat back and K&N intake running 16.4 sec @ 80.0 mph, but it doesn't state 4wd or 2wd... A general rule of thumb in the 1/4 is +10hp = -100lbs = -0.1sec, but even that has its limits... However, based on that, if you could drop 200-300lbs from the truck (think spare tire, additional seats, carpet, etc), you'd stand a chance...

*EDIT* - noticed an error in the weight of the VW. Changed it there and updated this posts math. Also had a problem with the weight of the Blazer. Things are looking much closer now...

Cougar send VeeeDUB packin'.. Oh snap!!! I just dropped it like its hot, yo... lol.. love those commericals..

"Factory stock"??? lol.. I dont know the meaning of the word :)

1.1 deficit, you = owned


What is done to the blazer? intake? Intakes add little to nothing at the rear wheels where it counts, those HP specs are at the crankshaft not the rear wheels, its about a 15% drivetrain loss with rear wheel drive, atleast thats what the engine and chassis dynos have proven to me on my camino.


Its an SUV take it in the dirt not the track, leave the track to fast cars and the streets to the public.

Youre right,, thats what the Cougar is for... I wasnt the owner of my Blazer when that stuff was done to the engine... I bought it because it was cheap.

Wasnt meaning it towards you, I mean if its fast sure take it and make some money at the track but if its a daily driver treat it like one and dont abuse it. Going Fast= Broken Parts.


All it does is feed the SUV asshole stereotype of being a road hog and offensive drivers if you mess around on the street in plain view of any public.

I know what you mean. Im not really sure what my Blazer will do... Its old and quite frankly it scares me anyway... My Cougar is pretty decent.. It will do mid 15s with just me in it and no stereo crap in the trunk, so Id have my hands full with a manual passat according to the time provided.. I ran down a Jetta turbo (already pointed out its similar to Passat),, assuming it was an automatic given the provided track times...

Only 15's? Must be a V6

Only 15's? Must be a V6



No sir, 4.6 Modular SOHC 220hp estimated. The V6s that they put in those things were dogs, I think they run 17s.

Wow..... I hope you got alot planned for it.

Check DSS.




How heavy are they? 4k+ ?

4,950 lbs according to the sticker in drivers side door well.

Oh, I have nothing planned too fancy for now.. I have a Cold air and about 100 pounds dropped out of the trunk (spare tire, scissor jack and some trunk padding). I'll probably put a computer programmer in it next spring (Im taking it off the road the first appearence of salt on the roads- winters get rough here).. I have a loan on it, so Id like to get payments on it before I do anything wild (Had it since April)... A factory stock Lincoln Mark VIII DOHC will bolt right on to the tranny and with the torque converter from it will make it run high 13s from my research. With dual 3 magnaflows.. Jasper has a reman. DOHC for I think 3500 with the core charge. Dont know what or if theyd take the SOHC for a core though.

i beat a couple of those before..:D hahha they get so madd.hahhaha. but i have trans work and a reprogrammed pcm..so i can run a 14.7;) in the 1/4. i have 01 2dr. 2wd. too.

I'm gonna call BS on that time. So you are saying that you've picked up over 1 second on a stock 2dr 2wd truck with your mods??? What was your trap speed? How about your 60' time or 1/8th time/speed?

My Bonneville with more power (240hp stock), about the same weight, and more torque (280ftlb stock) only runs 14.84sec in the 1/4 for my personal best. I highly doubt that you've picked up 50hp and 30ftlb with a PCM and trans work...

Maybe 30 at best... Whats the programmer good for? 20 would be generous.

Now, trans work, while shortening and firming up shifts, it will not increase the performance of the vehicle. It will result in less wear on the clutches, but not lower the hp loss through the transmission.

And some of the best all-in-one PCM programmers are good for maybe 15hp, 20hp MAX. A custom burn may yield 25hp TOPS, but with no other mods, you'd be hard pressed.

Now, firming up shifts might improve the 1/4 mile times SLIGHTLY without giving any horsepower, but would mostly serve the purpose of saving the transmission right? 14s??? in a Blazer? Im not sure who would want to let alone claim to be able to...

call all the bs you want. i have a custom trans. no simple mods like a lot of people run. i have a custom servo not a corvette one. it doesnt shift out of 1st till 40. and other trans mods. i have 3.42 rearend. as the the pcm its a custom tune not a programer. and with the trans work we were able to squeze a couple more #'s out of the motor by adjusting the trans electronically. plus when i race i run a smaller tires in the rear for added traction and to give it a little more gear. Some of you people need to put your calculators away and learn to feel a car. ive learned that, cause every car is different even tho they are supposed to be the same. any way back to the subject its not bs lol :D

Good, then back it up with a dyno sheet and a timeslip... thanks...

Again, servo's/shift-kits/etc do not decrease the hp loss through an automatic transmission.

You come on here and your first post is bragging about a 14.7sec - 1/4 mile when we have a nitrous blazer (02 Vortech) using a progressive 100 shot nitrous system running 9.29sec - 1/8 mile which translates to about a 14.31sec - 1/4 mile. That's with 100shot of nitrous! Not just a tune with no supporting mods. The gears will help... some... But still haven't accounted for a full half second of ET. Again, what was your trap speeds in the 1/4? in the 1/8th? Your 1/8th time? 60' time?

Looks like someone took their expected hp and curb weight and threw it into an online calculator to me. Until slip(s) are produced, I stand with my BS call.

i didnt use an online calculator. anyways i cant find my timeslip from my july test and tune. im goin back this coming wed. to milan for a test and tune then ill put them up for u guys. Relax killers lol hahaha. look i know what u guys are sayin i said the same thing when i bought my blazer. but then i raced it stock and it ran a 16.5(cant find time slip) with nothing(not cai, filter nothing) ive done alot since then. for some reason my blazer is just faster than others. look say what you and you do have the right to put up a bs flag cause i cant find my timeslip. but no worries ill put it up next thursday.

for some reason my blazer is just faster than others.

lmao hahah that funny except for number 2. lol anyway 14.7 in a N.A. blazer is possible ill get the timeslip next week. 4.3 are faster little motors because of their Torque(which is what moves you) so change the trans to make better use of the torque curve is what i did. its not a normal trans at all. then with the pcm flashed to aid it even more. look theres things you can do to these motors to make them scream. hint hint dont cut the eye lid in the intake all the way out=bad bad. notch it and polish the SH*T out of that mofo and the whole intake. then make a custom cia. HEAT WRAP It. AFTER I HEAT WRAPED IT AND PUT HEAT SHIELDS IN= awsome.

Actually, let me retract my gear ratio statment. At 3.42, you're ratio is higher than my Bonneville (with 2.93) true, but unless you've picked up more than 50hp and 30lbft (which L67 motors are notorious for being underrated by GM), you are still behind me. A 3.42 is actually one of the worst ratio's found in a stock 4.3L blazer for 1/4 mile times.

You are sticking to your guns with that trans too... So what exactly did you do to it? Unless you changed the internal gear ratios, you haven't changed things that much to improve your times noticably. And as far as I know, there isn't anything available to change these ratios internal to the trans... Not to mention that a rear gear swap to say a 3.73 or 4.10 would have been much more cost effective and would have yielded better results.

And yeah, the 4.3L has good low end grunt, but at the expense of anything high end unless you do significant work to the motor to improve it's flow (which, in most cases, hurts your low end power).

But I'll ask again, what were your trap speeds in the 1/8th? and 1/4? How about your 1/8th time? 60' time?

i cant give the what exactly what was done too the trans...well cause i didnt do it...but i had it hooked up to a genisis and did a recall on history problem with the car. and it had two pages of trans issues. so i put it up on the lift and look at the trans with my friend(who owns a trans shop) and he said that my trans was recently just put in. now that i dont know exactly what was done i will say this... from a 30mph roll i romp on it and it revs the motor up too 5000-5500 and just DUMPs it in too 1st=the funnest thing ever lol hahha. it shifts at 35-40 into second and than again at 65-70 into third and i havent found out yet when it shifts into 4th yet. o by the way I LOVE L67 motors. my dad has a 99 gtp runs 13.88-13.90 inthe quarter with 102 trap. its hard to launch that car with street tires. I'll get the ur #'s for you next thursday im goin wednesday to milan.

So that guy never did come back with a timeslip did he?

In another thread he went to the track and only made one run. 0.6xx RT with an ET of 15.8 something at 84mph and a 2.2sec 60' time. He said he spun through first gear and into second, which doesn't jive with his 60' time.

My blazer runs low 10s...

Mods? Catalytic converter removed.

For some reason mine is just faster than others. :)

yea...k&n air filter, exhaust tip, and other secret mods done to mine. How about 13.6 in the quarter..and i even took two spark plugs out before the run!!! by the way, i'm just kidding!! Ain't gonna try to run it down the track, it's my daily driver.

Ok guys, that's enough... What's done is done.
