Jeep SRT8 - Finally Got One Of My Fave Cars Ever -

Never spotted this!
4.5s to 60 and 1/4 mile a smidge under 13s is damn quick mate. I managed a 12.9 once in my Mustang with 460HP, damn manual gearbox and a 12.9s in my E46 M3 which had 360HP and weighed 1300kg, but again damn SMG.

Just proves how effective a decent automatic is at launching of the line and not fluffing any gear changes as your truck is absolutely hauling, bet you must love it if you get a hot hatch along side you and you then just decimate them off the line. :D

Does it have cylinder deactivation when cruising? If so suspect it will do 25+ on a run, did a 600 mile round trip in the M5 this weekend, average for weekend was 20mpg and on motorway it was returning 23mpg at 85mph and 26mpg at 70mph, so if can't see yours being too far of that considering the M5 has no overdrive or cylinder deactivation and is feeding 10 hungry cylinders, lol. :D

Hahaha, cheers man appreciate,d nice to know people appreciate just raw muscle, nothing complicated with fancy engine tricks, turbo's etc etc... it's just raw silly power and sound... chuffed with it now, but more power is needed next year, but that'll be super charger as unless you stroke these to 426's and cams, you're limited. a reprofiled cam alone can add 50bhp@wheels incredibly with original springs/lifters etc. generally if you bore them out to 7.1 litre (i.e. 426) then add cam and headers you're looking over 600bhp... and a fuel econmy around 8mpg lol.

Right now, this is as far is it'll go with standard tweaks etc. Yeah it does feel good, because to look at it, you'd neveer think it could do what it does and it's fail safe. Basically off the line in wet or dry, it'll be 4.5-4.8 tops... where'as controlling power in RWD or FWD cars is hit and miss and takes a some skill, this thing you just nail it, it lifts the bonnet up and throws itself down the line. Love it.

As for the cylinders no, thankfully it's 8 all the time and the reason I say thankfully is, all the recent post 2012 MDS enabled SRT's with the slightly bigger 6.4ltr all the lifters go, cams and rods... pretty much all fail and I believe as do otehrs it'linked to the deactivation of the cylinders... so, the 6.1ltr is where it's at. Also, it's the most robust engine for tuning... so, safe for 650bhp before you even have to think about transmission, diffs etc. which is nice to know. Its' getting 15.1mpg on small crappy runs, but bet I could be doing wayyy over 20 on a long run on a motorway I reckon, cruising at 80.

Looks great, it’s the little things that lift a project. Thank you for sharing your journey :D
Cheers mate, appreciated, glad you like it. He's in today... getting an exhaust mod... so, I think over the next couple of days, you guys deserve some footage and sounds... which I've promised but not delivered on... well that time has come...
 
Ok, video of the sound it produces now... not the best quality as was on a mates phone and also, the SRT8 has a rev limiter think it's to around 3,000rpm I think to protect the engine but this gives an indicator of the soudn this generates. Enjoy.

 
Cheers guys, yeah, can't wait to get some proper videos of it this weekend in good video quality and also better sound, possibly a off the line and driveby or something
The rev limit was a European legislation for noise and pollution IIRC. Most new cars have it :(. Sounds tasty, looks good as well.
That sounds beautiful!
Yeah sounds like a proper muscle car now, so will have some fun this weekend and try and get a few proper videos. be nice to get a couple of drivebys
 
Well, as yesterday was hot I noticed that the AC wasn't cold... so, popped into ATS today to get it regassed or at least vacuum checked... so, vacuum check passed, all good, however, they said laughing no wonder it wasn't working, instead of 500 (whatevers, sure they said grams, but whatever), I had 5 (whatevers) so basically empty. So they couldn't rule out a tiny leak, but they couldnt' see anything so filled to the brim and working like a wizard. Will keep an eye on it as they also said they put a UV liquid in as well so if it does leak I'd be able to see where. Fingers crossed, but reckon as I'd not seen any AC servicing, my assumption is, it was empty!

So, £60 quid with some bacterial something or other so, hopefully all will be good now for a couple of eyars!

So, last week me and my 12 year old after Jujitsu pulls up at lights. In rear view mirror MX5? I think comes up driving fast and slams on... all exhausts and bits done all the usual thing. Anyway, he's there reving with his girlfriend smiling as you do... ok... what we racing man? Really? I'm hoping he's gone turbo's or something... didn't look like it to me... however when they caught up at the end, both gave thumbs up and shouted awesome from their car... think they realised it wasn't any ordinary Jeep hahaha My little girl loved it and showed all her mates at school the next day.Now just need to wait for an M3 or something, give them a worry!

Just good fun, pity I didn't have the footage with the Audi from the other week.. it's been written over!

 
Well it was time for an oil change, so, jacked the beast up... christ could Jeep make it any more awkward to get at the damn oil filter... pipes and crap all around it. Anyway, once I'd done that, could I find a damn 13mm socket for the sump plug hahaha... nope... then when I got one... my torque wrench, couldn't find the adaptor so what should've been around a 30 minute job turned into 2 hours of messing around hahaha. However, all done and around 6.2ltr's of Mobil 1's finest now in and uprated Oil Filter this time around!

Couldn't do the rear bump stops as couldn't get the right angle to dig the knackered ones out, so threw dummy out the pram... and thought stuff it hahaha

So, this week need to work a way of getting at these bump stops out and replace... trying to do everything myself nowadays now I'm not contracting and save as much money as possible and stop being idle lol.
 
Well, decided to replace the bump stops on the SRT8 this weekend, only took an hour, but reckon these were the originals from 2010... blimey... bit of a pain in the arse though to get the old ones out without messing around taking suspension off, but got there in the end!

Any new ones installed... 1 hours work but worth it

Decided to get an early MOT as I didn't want to be messing around in November with MOT's as I've got a lot on around that time, so while I knwo it's mint off he went. Obviously passed, then looked up and hes' never failed... nice to see a sea of GREEN PASSES. So, onwards and upwards with the big guy.

Well, in a few days time, off to Scotland in the Jeep. So picked up an emergency 20ltr jerry can which I'll carry with me incase antyhing goes pearshaped :-) Never had to take emergency petrol but better safe than sorry. Also, mayb have to detune the car if running normal everyday petrol as well which is annoying but hey ho. Be interesting driving this across some epic roads... test the thing out a little :cool::cool::cool:
 
Love that SRT, I always visit Auto Trader, there’s two of that shape but yours looks far nicer.
Cheers buddy appreciated. There is a 3rd appeared, but seems to be changing hands a lot, was a looker and I was about to go and look at it in February, then it sold... then it was back up for sale 6 weeks ago in Scotland... looking a little scruffier than original photo's. Now it's just appeared today for an additional £2k on top of the cost of what the guy in Scotland was selling some 6 weeks ago. I reckon this dealer bought it for around £11-11,5k given it a clean etc and trying to make a quick buck... well around £3k of profit...

However, it's been flying through MOT's... and it did look mint!

Well, time for another oil change (done 3,300 miles since last one), so out with the Mobil1 0/40 again and the SRT Hellcat oil filters... and while at it... flush the coolent all out and through and put some nice new stuff in!!!

Next week will be the dreaded transmission fluid drain (50% drain)... and a new sump with a drain plug to make it a damn sight easier going forward!!!
 
hahaha, wow, wasn't excpecting this, but feel free to carry on. The question is, do I need this bag of crisps infront of me... the answer is no... am I going to eat these bag of crisps... DAMN RIGHT as I love crisps :-)
 
Ok, so, before Thursday big day of changing the Transmission fluids... I thought I'd get some baselines now... so I know we've got the right amount in now and also, to check the colour and smell, see how good or bad the current fluid is at 46k miles... So, by using the following graph, running the engine and allowing tranny to warm up... I used the ODB2 connecting for live data and trans temps in both D and R... and then measured... with the new dipstick I've just purchased (Jeep don't supply and lock off the tranny fluid intake)...

So, my figures were:

100F = 40mm
108F = 45mm
115F = 50mm

All these figures seem right now on that graph.Didn't bother going higher as I knew looks like it's fine.

As for the condition of the fluid... smells kinda weirdly sweet (not burnt) and the colour looks really solid.. almost like it's been done in the past but hard to say, certainly not burnt though.

However, that's not going to stop me from dropping the fluid twice (once then a 15 minute drive then drop and refill) to get as much out as I can. Also, as Jeep don't have a pan with a drain plug, when we change first drop, I'm changing to the Mercedes Pan for the 722.6 NAG1 which comes with a drain hole! Jeep need shooting for things like this!

I don't know if it's a help at all but just by you is Chester Automatic Transmission Centre who are ZF gearbox specialists and have a machine which gets 99% of the GB oil out, inc all the additional oil stuck in the TQ, preventing the need for a second flush/refill. I've used them twice for my previous RS6's ZF Gearbox drain/refill/service and they were quite cheap.
yeah cheers was contemplating getting them to do it... and was determined to do it myself, learn to do things and all that. So, today we did it and it was easier than I thought. Dropped the pan and changed filter then basically Used the ODB2 and Transmission temp in D or R, measured whats' on the stick and job done. Dropped it twice... could've and would've done 3 but hey...
